Dealing with fine lines, wrinkles, or uneven skin texture can be a source of frustration. This potent serum is designed for those ready to take a serious step in their anti-aging routine, using a multi-faceted retinol complex to promote smoother, firmer, and more youthful-looking skin.

1. Cleanser — Wash your face with a gentle cleanser.
2. THIS PRODUCT (PM Only) — Apply a pea-sized amount in the evening. See "How to Use" for starting frequency.
3. Sunscreen (AM) / Moisturiser (PM) — Always use SPF 30+ in the morning. Use a nourishing moisturiser at night to seal in the serum and reduce potential dryness.

Note: Already own a similar active serum? Finish that first to avoid waste and prevent irritation (substitute, don’t stack strong actives).

This product is for PM use only due to the nature of retinol. An ideal AM routine to support its effects would be:

• Minimalist (3 steps): 1) Gentle Cleanser → 2) Hydrating/Antioxidant Serum (e.g., Vitamin C or Niacinamide) → 3) Sunscreen SPF 30+
• Optional: Add a moisturiser before sunscreen if your skin feels dry or your SPF isn't hydrating enough.
• Wait times: Allow 30–60 seconds between watery layers and at least 1–2 minutes before applying sunscreen to ensure a proper film forms.

• Minimalist (3 steps): 1) Cleanser (double-cleanse if wearing makeup/sunscreen) → 2) THIS PRODUCT → 3) Moisturiser
• Optional: On nights you do NOT use this serum, you can use a gentle chemical exfoliant (1-2x a week). Avoid using them on the same night.
• Texture rule: Apply to clean, dry skin. Follow with thicker creams or oils.

Retinoid Introduction Protocol (Crucial for beginners):

• Weeks 1-2: Use once every other night (e.g., Mon, Wed, Fri).
• Week 3 onwards: If no significant irritation, increase to nightly use. If your skin is sensitive, you may prefer to stick to 3-4 times a week.

Nightly Use — PM Only:

• Amount: A pea-sized or grain-sized amount for the entire face. Using more does not increase results, only irritation.
• Apply to: Clean, completely dry face and neck. Avoid the delicate skin around the immediate eye area, corners of the nose, and mouth.
• Method: Dot onto forehead, cheeks, and chin, then gently spread into a thin, even layer.
• Wait times: Wait 5-10 minutes for it to absorb before applying your moisturiser.

The "Sandwich Method" for Sensitive Skin:

To reduce potential irritation, "sandwich" the retinol between layers of moisturiser:

1. Apply a thin layer of a simple, barrier-friendly moisturiser to clean, dry skin.
2. Wait a few minutes, then apply the Medicube Retinol Serum.
3. Wait another 5-10 minutes, then apply a second layer of your moisturiser.

Watchouts: A warming sensation, mild redness, or some initial peeling can be normal as your skin adapts. However, if you experience significant burning, itching, or a rash, stop use and focus on barrier repair. Sunscreen in the morning is NOT optional—retinoids make your skin more sensitive to the sun.

Safety: Do not use on broken or irritated skin. Do not use if pregnant or breastfeeding. For teens, focus on a basic routine of cleanser, moisturiser, and SPF; avoid strong actives like retinol unless guided by a clinician.

This is a strong active for PM use. Do not use it on the same night as other strong exfoliants (AHA/BHA).

Example Week (PM Focus for a Beginner):

• Monday: THIS PRODUCT
• Tuesday: Soothing night (no strong actives; focus on hydration with ingredients like snail mucin or ceramides)
• Wednesday: THIS PRODUCT
• Thursday: Soothing night
• Friday: THIS PRODUCT
• Saturday: Soothing night or a hydrating sleeping pack
• Sunday: Soothing night

Rule of Thumb: One strong active per night. Listen to your skin—if it feels irritated, take an extra soothing night off.

Mauritius note: The high UV index year-round makes daily SPF use essential to protect your results and prevent sun damage, which retinoids can make you more susceptible to.

• Immediate: The serum has a smooth, moisturizing feel upon application. Some users may experience a warming sensation or initial dryness.
• 2–4 Weeks: You may experience "purging," where underlying congestion comes to the surface as skin cell turnover increases. Skin texture may start to feel smoother. This is the adaptation period.
• 4–8+ Weeks: With consistent use, you can expect a visible improvement in skin texture, a reduction in the appearance of fine lines, and a more even skin tone. Effects on deeper wrinkles and firmness become more apparent with long-term (3-6 months) use.

*Individual results vary. Consistency and diligent sun protection are key to achieving the best outcomes.

• Why use a formulated Retinoid Serum, not DIY Vitamin A masks? Cosmetic retinoids are scientifically formulated for stability and skin penetration. DIY alternatives like carrot masks lack the correct form of Vitamin A (retinoic acid or its precursors) to produce clinical anti-aging effects and offer no reliable dosage.
• Why start slow, not use it every night from day one? More is not better with retinoids. Using it too frequently at the start overwhelms the skin's receptors, leading to a damaged skin barrier (redness, peeling, irritation) rather than faster results. A slow ramp-up allows your skin to build tolerance for optimal long-term benefits.
• Why use this instead of prescription Tretinoin without guidance? This is a potent cosmetic product designed for over-the-counter use with built-in soothing ingredients. Prescription tretinoin is a powerful medication that is more effective but also has a much higher risk of severe irritation and should only be used under a doctor's supervision.

• Works Well With: Hydrating and soothing ingredients. Pair with Hyaluronic Acid or Snail Mucin (applied before on damp skin, let dry), and seal with moisturisers containing Ceramides and Panthenol to support the skin barrier and minimize dryness. Niacinamide can also be used in the same routine for additional skin-balancing benefits.
• Use with Caution: Other strong actives. Do not use on the same night as high-concentration AHAs or BHAs. If you wish to use both in your routine, alternate nights. For Vitamin C, it's best to use it in the AM and this retinol serum in the PM to maximize the benefits and stability of each.
• Avoid On: Do not apply to eyelids, corners of the nose, or mouth. Avoid applying to broken, wounded, or sunburned skin.

• Oily & Combination Skin: Excellent. Helps regulate cell turnover which can prevent clogged pores, and can improve the appearance of pore size over time. Its serum texture is generally well-tolerated.
• Normal Skin: A great choice for targeting signs of aging.
• Dry Skin: Suitable, but must be paired with a robust moisturizing routine. Use the "sandwich method" and follow with a rich, barrier-supporting cream to counteract potential dryness.
• Sensitive Skin: Proceed with extreme caution. This is a potent product. A patch test is mandatory. Start with the lowest possible frequency (1x per week) and consider a gentler alternative like Bakuchiol if your skin is highly reactive.

• Fine lines and wrinkles (crow's feet, smile lines)
• Uneven and rough skin texture
• Loss of skin firmness and elasticity
• Enlarged or sagging pores
• Dullness and lack of radiance

Key Actives Explained:

• Retinoid Complex: The brand refers to a "seven-layer retinol" complex which includes multiple forms like Retinol, Retinal, and Granactive Retinoid. These are Vitamin A derivatives renowned for their ability to accelerate skin cell turnover, boost collagen production, and refine skin texture.
• Niacinamide: A form of Vitamin B3 that helps brighten skin, improve the appearance of pores, calm inflammation, and strengthen the skin barrier.
• Squalane: A stable, plant-derived oil that is highly moisturizing and helps to repair the skin barrier without feeling heavy.
• Panthenol (Pro-Vitamin B5): A humectant that attracts and holds moisture, soothing the skin and supporting barrier function.
• Hydrolyzed Collagen: A form of collagen broken down into smaller fragments. Topically, it primarily functions as a humectant to hydrate the skin's surface.

Full INCI List:

Water, Dipropylene Glycol, Butylene Glycol, Glycerin, Propanediol, 1,2-Hexanediol, Niacinamide, Coco-Caprylate/Caprate, Squalane, Polyglyceryl-3 Distearate, Dimethyl Isosorbide, Pentylene Glycol, Panthenol, 4-t-Butylcyclohexanol, Fragrance(Parfum), Hydrogenated Lecithin, Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer, Glyceryl Stearate Citrate, Sodium Polyacryloyldimethyl Taurate, Carbomer, Tromethamine, Ethylhexylglycerin, Adenosine, Disodium EDTA, Sorbitan Isostearate, Hydroxypinacolone Retinoate, Polysorbate 20, Retinol, Hydrolyzed Collagen, Madecassoside, BHT, BHA, Tocopherol, Retinal.

Formulated Without: The brand states its retinol products are free from artificial colorants. This specific formula is not alcohol-free.

• Fragrance Status: Contains added fragrance ("Parfum"). Users describe the scent as fresh but mild, and it dissipates quickly after application.
• Intensity: 1/5 (very light).
• EU Allergens: The full INCI does not list common EU allergens like Linalool, Limonene, etc., but the generic term "Parfum" can contain them. A patch test is strongly advised for those with fragrance sensitivities.

Who should use with caution:

• Individuals with very sensitive or reactive skin, or conditions like rosacea or eczema, should approach this product with extreme caution or avoid it.
• First-time retinol users.
• Do not use if pregnant or breastfeeding.

Patch Test Protocol:

1. Apply a tiny, rice-grain-sized amount of the serum to a discreet area, like behind your ear or on your inner arm.
2. Wait 24-48 hours and observe for any signs of a negative reaction, such as a burning rash, significant redness, or itching.
3. If no reaction occurs, you can proceed with a patch test on a small area of your face (e.g., along the jawline).
4. If your skin remains calm, you can begin incorporating it into your routine as per the "How to Use" guide. Discontinue use immediately if a reaction occurs.

• Texture & Finish: A lightweight, moisturizing serum or gel-like consistency that absorbs quickly into the skin without a heavy or greasy residue.
• Scent: A mild, fresh scent that is not overpowering.
• pH: Stated as approximately 6.3, which is close to the skin's natural pH, helping to minimize irritation.
• Fungal Acne (Malassezia) Compatibility: Contains Squalane and Polysorbate 20, which can be potential triggers for fungal acne. Patch testing is advised for those with FA-prone skin.

• Issue: My skin is red and peeling.
  Fix: You are likely using it too often or using too much. Reduce frequency to 1-2 times per week and ensure you are only using a pea-sized amount. Apply a barrier-repairing cream (with ceramides or panthenol) on top. Take a few "soothing nights" off until the irritation subsides.
• Issue: I'm breaking out more than usual.
  Fix: This may be "purging," which is a temporary increase in breakouts as the retinol speeds up cell turnover. It should resolve within 4-6 weeks. However, if the breakouts are very inflamed, itchy, or occur in areas where you don't normally break out, it could be an irritation response. In that case, stop use.
• Issue: The product is pilling (rubbing off in little balls).
  Fix: This usually means you've applied too much product or haven't allowed sufficient waiting time between layers. Use a smaller amount and wait for it to fully absorb before applying your next product.
• Issue: I'm not seeing results after 8 weeks.
  Fix: Ensure you are using it consistently. Also, are you wearing sunscreen every single day? Sun exposure can counteract the benefits of retinol. Results for fine lines and wrinkles can take 3-6 months of consistent use to become noticeable.

• Humid Summers: The lightweight serum texture is well-suited for Mauritius' humid nights, as it won't feel heavy or suffocating. You may find you only need a light gel-cream moisturiser on top.
• Drier/Cooler Winters & AC: In the cooler months or if you sleep in air-conditioning, your skin may feel drier. Be sure to layer a more substantial, nourishing moisturiser over the serum to prevent moisture loss.
• Sun Exposure: With the high UV index in Mauritius year-round, daily application of a broad-spectrum SPF 50+ sunscreen is absolutely mandatory when using this product. There are no exceptions. This will protect your sensitized skin and the results you're working to achieve.

• Brand Test: Medicube has conducted and published its own internal human application tests on its retinol products, reporting specific percentage improvements in various signs of aging like fine lines, skin density, and pigmentation.

*Brand claim—no public dataset available for independent verification.

A 30ml bottle contains approximately 600 drops. Using 2-3 drops per application:

• Starting out (3x a week): The bottle will last approximately 33-50 weeks.

• For a Gentler Introduction to Anti-Aging: EQQUALBERRY Bakuchiol Plumping Serum 30ml — Choose this if your skin is very sensitive or you are new to anti-aging actives. Bakuchiol is a plant-derived ingredient known as a gentle, natural alternative to retinol.

Mindful-use: If you already have a comparable retinol or active anti-aging serum at home, finish it first to avoid waste and get a fair read on its results before introducing a new one.

• Format: 30ml tube, often with a precise applicator tip to dispense a controlled amount, which is hygienic and prevents over-use.
• Stability & Storage: Retinoids are sensitive to light and air. The opaque tube helps protect the formula. Store in a cool, dark place (like a drawer or cabinet) away from direct sunlight and heat to maintain potency.
• Recycling (Mauritius): The plastic tube and cap can typically be recycled. Please rinse the container before disposing of it in your local recycling bin. The outer cardboard box is fully recyclable.
• Travel: The 30ml size is travel-friendly and compliant with airline carry-on liquid limits.

Aggregated sentiment from independent reviews suggests users appreciate the serum's lightweight, non-greasy texture and its effectiveness over time.

• Positive Takeaway: A user on Ballagrio (2025-09) noted, "The texture is perfect, and allows for noticeable difference within just a few weeks. I highly recommend this product." Many users confirm that starting slow (every other day) is key to avoiding irritation.
• Positive Takeaway: Another reviewer on Kiyoko Beauty (2025-09) who was able to use it without irritation said, "This may be the only retinol I can use with zero irritation. It's a nice light gel consistency that is quickly absorbed. Works very well to decrease stubborn wrinkles, uneven skin tone."
• Fair Caveat: As with any potent retinoid, some users experience an initial purging period or dryness. The most successful users emphasize the importance of following the ramp-up instructions and pairing the serum with a good moisturiser and daily sunscreen.

Note: These are anecdotes from individual users. Your experience may vary.

Medicube is a South Korean clinical-grade "derma-cosmetic" brand that focuses on developing effective, science-backed solutions for common skin concerns. They work with dermatologists to create products that are both potent and safe, often publishing their own clinical test results to substantiate their claims. Their philosophy bridges the gap between gentle daily skincare and professional dermatological treatments, making advanced, reliable care accessible at home.

• Retinoid: A class of Vitamin A derivatives (includes Retinol, Retinal, and prescription Tretinoin) known for their ability to promote skin cell turnover and boost collagen production.
• Retinol: A common over-the-counter form of retinoid. It needs to be converted by the skin into retinal, then retinoic acid, to work.
• Retinal (Retinaldehyde): A more potent form of retinoid than retinol because it requires only one conversion step to become retinoic acid, making it faster-acting.
• Purging: A temporary increase in breakouts that can happen when starting a new active ingredient like a retinoid. It's caused by the product speeding up the rate at which underlying micro-comedones come to the surface.
• MFDS: Ministry of Food and Drug Safety in South Korea, the regulatory body that classifies functional cosmetics.
• PAO: Period After Opening. The symbol on packaging (an open jar with a number like "12M") that indicates how many months the product is safe to use after being opened.

Can I use this serum if I have sensitive skin?

This is a potent retinoid product. If you have sensitive skin, it is crucial to perform a patch test and start with the lowest possible frequency (once a week), using the "sandwich method" with a good moisturiser. If any significant irritation occurs, discontinue use. A gentler alternative like Bakuchiol may be more suitable.

Is it normal for my skin to peel or feel warm after using it?

Yes, a mild warming sensation, some initial redness, and light peeling (retinization) can be normal for the first couple of weeks as your skin adapts. This should subside. If it is severe or painful, you are likely using too much or too often. Reduce frequency immediately.

Can I use this product in the morning?

No. Retinoids should be used at night as they can be degraded by sunlight and make your skin more photosensitive. Always wear a high-SPF, broad-spectrum sunscreen during the day.

How is this different from a prescription retinoid like Tretinoin?

This is a cosmetic serum formulated to be effective yet suitable for over-the-counter use, often including soothing ingredients to minimize irritation. Prescription Tretinoin (retinoic acid) is a much stronger medication that works more quickly but also has a significantly higher potential for side effects like severe dryness and peeling. It should only be used under the supervision of a doctor.

• Best For: Individuals with normal, combination, or oily skin looking to address fine lines, wrinkles, uneven texture, and loss of firmness.
• Key Benefits: Contains a powerful complex of retinoids to visibly improve signs of aging. Formulated to be effective while minimizing irritation common with retinoids.
• Keep in Mind: This is an advanced treatment. It requires a slow, careful introduction into your routine. Daily sunscreen use is non-negotiable. Not suitable for very sensitive skin, or for use during pregnancy or breastfeeding.

• Coverage: Island-wide delivery (Mauritius).
• Processing & Timing: Orders process in 1–2 business days. After pickup by our partners, delivery typically takes 1–5 business days.
