Dealing with stubborn dark spots from the sun or leftover acne marks can be frustrating. This serum is a gentle, beginner-friendly treatment designed to help brighten your complexion and even out skin tone, without the harshness of stronger vitamin C formulas.

• What it is: A lightweight, gel-like serum powered by 70% Green Tangerine Extract, a natural source of Vitamin C derivatives.
• Who it's for: Ideal for those with normal, combination, or oily skin types looking to fade hyperpigmentation (PIH), sun spots, and achieve a brighter glow.
• Key Benefits: Visibly brightens the complexion, helps fade the appearance of dark spots, and provides a boost of antioxidant protection. Its hydrating formula is comfortable for Mauritius's humid weather.

1. Cleanser: Wash your face with a gentle cleanser to start with a clean base.
2. THIS PRODUCT: Apply 1-2 pumps of the Green Tangerine Serum to your face and neck.
3. Sunscreen (AM) / Moisturiser (PM): Always follow with a broad-spectrum sunscreen in the morning to protect your results. At night, follow with a moisturiser.

Note: Already own a similar brightening serum? Finish that first to avoid waste (substitute, don’t stack).

Minimalist Routine (3 steps):

1. Cleanser: Start with a clean face.
2. Green Tangerine Vita C Serum (THIS PRODUCT): Apply 1-2 pumps. It provides antioxidant protection against environmental stressors throughout the day.
3. Sunscreen (SPF 30+): This is a non-negotiable step. Vitamin C works best when protected by sunscreen, which prevents new dark spots from forming in Mauritius's high UV environment.

Wait Times: Allow the serum to absorb for 60 seconds before applying your sunscreen to prevent pilling.

Minimalist Routine (3-4 steps):

1. Cleanser: Double cleanse if you wore makeup or water-resistant sunscreen (use an oil cleanser, then a water-based foam/gel cleanser).
2. Toner (Optional): A hydrating toner can prep the skin and boost absorption.
3. Green Tangerine Vita C Serum (THIS PRODUCT): Apply 1-2 pumps to work on repairing and brightening your skin overnight.
4. Moisturiser: Lock in the serum and provide hydration with a suitable night cream.

Texture Rule: Always apply products from the thinnest texture to the thickest.

• Amount: 1-2 pumps for the entire face and neck.
• Apply to: Cleansed skin. Can be applied after toner, if you use one.
• Method: Gently spread across the face and pat lightly to aid absorption. Avoid the immediate eye area.
• Frequency: Start with once daily (either AM or PM) to see how your skin tolerates it. If well-tolerated after a week, you can increase to twice daily.

If-This / Then-That:

• If your skin is very oily: This lightweight gel is perfect. Your sunscreen might provide enough moisture for daytime.
• If your skin is combination/dry: Layer a hydrating toner before the serum and a nourishing cream after, especially at night.
• If your skin is sensitive: Patch test first. This serum contains natural citrus oils. Start with use every other day before increasing frequency.
• If you are using retinoids or strong acids (AHA/BHA): Use this serum in the morning and your retinoid/acid at night. Do not use them in the same routine to avoid potential irritation.
• If you wear makeup: Wait a full 1-2 minutes after application before your sunscreen or primer to minimize the chance of pilling.

Safety: For external use only. Avoid contact with eyes. Discontinue use if a persistent rash or irritation occurs.

This serum is gentle enough for daily use, but here’s how to schedule it if you use other strong actives.

• Daily Use: Apply this serum every morning under sunscreen for antioxidant protection. You can also use it at night if you are not using other actives.

Example Week (PM focus if alternating):

• Mon: THIS PRODUCT (PM)
• Tue: Exfoliant (AHA/BHA) Night
• Wed: THIS PRODUCT (PM)
• Thu: Retinoid Night
• Fri: THIS PRODUCT (PM)
• Sat: Soothing / Hydrating Night (no strong actives)
• Sun: THIS PRODUCT (PM)

Rule: One strong active per night. Do not use potent Vitamin C serums, strong exfoliants (AHAs/BHAs), and retinoids in the same PM routine. This serum uses gentle Vitamin C derivatives, but it's best to alternate to be safe.

• Immediate: Skin feels hydrated and may have a subtle, healthy glow. The lightweight texture absorbs quickly, which is comfortable in Mauritian humidity.
• 2-4 Weeks: According to brand-led studies, some users may begin to see a visible reduction in the appearance of dark spots and a more even skin tone. (Brand test)
• 4-8+ Weeks: With consistent daily use and diligent sun protection, you should notice more significant improvements in hyperpigmentation, overall brightness, and skin clarity. Fading post-acne marks requires patience, and results become more apparent over time.

• Why use this serum, not DIY lemon juice? While lemons contain Vitamin C, the juice is highly acidic (pH 2-3) and unstable. Applying it directly to your skin can cause irritation, chemical burns, and even worsen dark spots when exposed to the sun (phytophotodermatitis). This serum uses a stable, gentle form of Vitamin C in a pH-balanced formula that is scientifically formulated to be effective and safe for your skin.

• Works Well With: Hyaluronic Acid, Snail Mucin, Centella Asiatica, Peptides, and most hydrating ingredients. It is essential to pair with Sunscreen (SPF 30+) in the morning for effective results and protection.
• Use With Caution: Avoid using in the same routine as high-concentration AHAs, BHAs, or Retinoids. It's best to alternate their use (e.g., Vitamin C in the AM, Retinoid/AHA in the PM) to prevent potential irritation and protect your skin barrier.

• Excellent for: Oily, Combination, Normal skin types.
• Good for: Acne-prone skin (helps with post-inflammatory hyperpigmentation), Dull skin.
• Use with Caution on: Extremely sensitive or rosacea-prone skin, due to the presence of natural citrus essential oils which can be potential irritants for some. Dry skin types will need to layer this with more hydrating products. A patch test is always recommended.

• Scent Intensity: 2/5 (A light, refreshing citrus aroma that dissipates shortly after application).
• Declared EU Allergens: Contains Limonene and Linalool, which are naturally occurring components of the essential oils used.

A patch test is highly recommended for those with known sensitivities to citrus extracts or essential oils.

• Who should use with caution: Individuals with very sensitive skin, rosacea, or a known allergy to citrus essential oils should approach with caution.
• Pregnancy & Breastfeeding: Contains a gentle form of Vitamin C and niacinamide, but due to the blend of essential oils, it is recommended to consult with a doctor before use as there is insufficient published data.
• Patch Test Protocol: Apply a pea-sized amount to a small, clean area of skin, such as behind the ear or on the inner jawline. Wait 24-48 hours to observe any signs of irritation like redness, itching, or burning. If a reaction occurs, discontinue use.

• Texture: A lightweight, watery gel-serum.
• Finish: Absorbs well, leaving a hydrated, dewy finish that is not sticky or greasy.
• Scent: Natural, fresh citrus.
• pH: Approximately 6.8 (mildly acidic to be gentle on the skin barrier).
• Fungal Acne (Malassezia) Compatibility: Contains Polyglyceryl-10 Laurate/Myristate which can be potential triggers for some. Individual responses may vary; patch testing is advised.

• Issue: The product is pilling or balling up.

  Quick Fix: You may be using too much product or not allowing enough time for it to absorb. Use a smaller amount (1 pump) and wait at least 60-90 seconds before applying sunscreen or makeup.

• Issue: I feel a slight tingling sensation.

  Quick Fix: A mild, temporary tingling can be normal for some people when first using Vitamin C products. However, if it persists, becomes a burning sensation, or is accompanied by redness, stop using the product and soothe your skin with a simple moisturiser.

• Issue: I'm not seeing results after a few weeks.

  Quick Fix: Fading hyperpigmentation takes time and consistency. Ensure you are using the serum daily and, most importantly, applying a broad-spectrum sunscreen of SPF 30 or higher every single morning. Without sun protection, you are unlikely to see significant improvement as UV exposure creates new pigment.

• Humid Summers: The lightweight, gel texture of this serum is perfect for Mauritius's hot and humid conditions. It hydrates without feeling heavy or sticky.
• Drier Winters/AC Exposure: During the milder, drier winter months or if you spend a lot of time in air-conditioning, you may want to layer a more substantial moisturiser over this serum to ensure adequate hydration.
• Sun Protection: The high UV index in Mauritius makes the antioxidant properties of this serum beneficial, but it absolutely must be paired with a high-SPF, broad-spectrum sunscreen every day to be effective and prevent further sun damage.
• Storage: To protect the Vitamin C derivatives from degrading in the heat and light, store the bottle in a cool, dark place, away from direct sunlight (like a drawer or cabinet, not on a sunny windowsill).

• Sourcing: At Adilsons, we source all our products directly from the brand or their authorized distributors in South Korea. We guarantee 100% authenticity.

• Brand Test: Goodal conducted a consumer satisfaction study on 21 adults, where 95.2% reported being satisfied with the improvement in their skin blemishes after 2 weeks of using the serum. The full dataset and methodology for this study are not publicly available.
• Ingredient Rationale: The benefits of this serum are supported by the known functions of its key ingredients. Niacinamide and Arbutin are MFDS-recognized functional ingredients for brightening. Vitamin C (and its derivatives) is a well-researched antioxidant that helps fade hyperpigmentation. Centella Asiatica and Licorice Root extracts are widely documented for their anti-inflammatory and soothing properties, which can help calm the skin and reduce redness associated with post-acne marks.

"I've been using this for about a month now, and the dark spots on my cheeks from old pimples have definitely started to fade. It's not a miracle overnight, but it's gentle and my skin looks so much brighter overall. It has a nice citrus smell that I love in the mornings."

– YesStyle review (2024-05)

A user on the r/AsianBeauty subreddit mentioned that this serum gave them a "beautiful glow" and helped even out their skin tone. They found the texture to be perfect for their combination skin, as it hydrated without being greasy. They noted, however, that it took about two months of consistent use to see a real difference in their more stubborn sun spots.

– Reddit, r/AsianBeauty (thread 2024-03)

Fair Caveat: "I wanted to love this, but my very sensitive skin didn't agree with the essential oils. It caused a bit of redness for me. If you're not sensitive to fragrance or citrus, you'll probably enjoy it, as the texture is lovely. I had to switch to a fragrance-free option."

At Adilsons, we are committed to bringing you the best of authentic Korean beauty. We carefully curate our selection, ensuring every product is 100% genuine and sourced directly from brands or their authorized distributors. Our promise is to provide you with truthful information and effective products to support your skin health journey with integrity.

1. Can I use this serum with retinol or exfoliating acids (AHAs/BHAs)?
It is best to alternate them. Use the Green Tangerine Vita C Serum in your morning routine for its antioxidant benefits, and use your retinol or acid product at night. Using them together in the same routine could increase the risk of skin irritation.

2. Will this serum lighten my natural skin color?
No. "Brightening" products like this serum work to even out your complexion by fading dark spots caused by sun damage or acne. It will help restore your skin's natural, even tone and radiance, but it will not bleach or lighten your inherent skin color.

3. Is it normal to feel a tingling sensation when I apply it?
For some individuals, a very mild, temporary tingling can occur when first introducing a Vitamin C product. However, this should not be a painful or burning sensation. If you experience persistent discomfort, redness, or a rash, stop using the product as your skin may be sensitive to one of the ingredients.

4. How is this different from other Vitamin C serums?
This serum uses 70% Green Tangerine Extract, which contains natural Vitamin C derivatives. These are generally gentler on the skin than pure L-Ascorbic Acid, making this serum a great choice for beginners or those who have found other Vitamin C serums to be too strong or irritating.

Best For: Individuals with normal to oily skin who are new to Vitamin C and want to gently fade dark spots, post-acne marks, and achieve an overall brighter complexion.
