Dealing with stubborn dark spots, post-acne marks (PIH), or a dull complexion can be frustrating, especially in a sunny climate like Mauritius. This potent serum is designed for those seeking a brighter, more even-toned complexion by targeting hyperpigmentation at its source.

• Primary Target: Fading dark spots, post-inflammatory hyperpigmentation (PIH), and sun spots.
• Secondary Benefit: Boosts overall radiance and protects skin from environmental damage with powerful antioxidants.
• Texture & Feel: A lightweight, watery serum that absorbs quickly without stickiness.
• Best For: Most skin types, especially normal, combination, and oily skin concerned with dullness and uneven tone.
• Caution: Pure Vitamin C can be potent. Not recommended for extremely sensitive skin or those with a damaged skin barrier. Patch testing is essential.

1. Cleanse: Wash your face with a gentle cleanser.
2. Treat (This Product): Apply 2-3 drops of the Pure C 5.5 Glow Serum to dry skin.
3. Protect (AM) / Moisturise (PM): Follow with sunscreen in the morning or a moisturiser in the evening. Sunscreen is non-negotiable when using Vitamin C.

Mindful Note: Already have a Vitamin C serum? Finish that first before opening a new one to ensure maximum potency and reduce waste.

Using Vitamin C in the morning boosts your sunscreen's ability to protect against environmental damage.

[Minimalist AM Routine]

1. Gentle Cleanser: Start with a clean base.
2. [THIS PRODUCT] JUMISO Pure C 5.5 Glow Serum: Apply 2-3 drops to your entire face, avoiding the immediate eye area.
3. Moisturiser (Optional): If your skin feels tight or your sunscreen isn't hydrating enough, apply a light moisturiser.
4. Sunscreen: Finish with a broad-spectrum sunscreen with SPF 30 or higher. This is a mandatory step.

Wait Times: Allow the Vitamin C serum to absorb for 60-90 seconds before applying moisturiser or sunscreen to prevent pilling.

While best used in the AM, you can use this serum at night. However, avoid using it on the same night as strong retinoids or exfoliating acids (AHA/BHA) to prevent irritation.

[Minimalist PM Routine]

1. Double Cleanse: Use an oil cleanser to melt away sunscreen and makeup, followed by a water-based cleanser.
2. [THIS PRODUCT] JUMISO Pure C 5.5 Glow Serum: Apply 2-3 drops to dry skin. (Alternate nights if using other strong actives).
3. Moisturiser: Lock in hydration with a suitable night cream.

Texture Rule: Always apply products from the thinnest consistency (like this serum) to the thickest (like a cream).

[Daily Use — AM Recommended]

• Amount: 2-3 drops for the entire face. Using more does not increase benefits and may cause stickiness.
• Apply to: Freshly cleansed, dry skin. Spread evenly across the face and neck.
• Method: Gently pat the serum into the skin until absorbed. Avoid rubbing.
• Frequency: Start with once every other day in the morning to assess tolerance. If your skin is comfortable after one week, you can increase to daily AM use.

[If-This / Then-That]

• If you feel a slight tingling: This is normal for a pure Vitamin C serum, especially upon first use. It should subside within a minute. If it burns or causes persistent redness, wash it off and discontinue use.
• If your skin is sensitive: Mix one drop with your moisturiser for the first week to buffer its potency.
• If the serum starts to turn yellow/orange: This means it has oxidized and lost its potency. Discard the product. To prevent this, store it in a cool, dark place (like the refrigerator).

[Safety First]

Avoid broken or irritated skin. Do not use on the same day as other strong exfoliants (AHA, BHA, physical scrubs) or retinoids. Always, always wear sunscreen during the day when this serum is in your routine.

This serum is designed for daily use, but it's important to schedule it correctly with other potent ingredients in your routine.

[AM Routine]

• Daily: Use the JUMISO Pure C 5.5 Glow Serum every morning, followed by sunscreen.

[PM Routine - Example with Alternating Actives]

• Monday: Hydration & Repair (e.g., Hyaluronic Acid, Snail Mucin, Ceramides).
• Tuesday: Exfoliant (AHA/BHA product). Do NOT use Vitamin C this night.
• Wednesday: Hydration & Repair.
• Thursday: Retinoid (Retinol/Retinal). Do NOT use Vitamin C this night.
• Friday: Hydration & Repair.
• Saturday: Exfoliant (AHA/BHA product).
• Sunday: Hydration & Repair or a nourishing sleeping mask.

Rule of Thumb: One strong active per night. Give your skin "rest" nights focused on hydration and barrier support in between active nights.

• Immediate (First 1-3 uses): Skin may feel slightly smoother and appear more hydrated. A healthy, subtle glow is often noticeable right away. Some users may experience mild tingling upon application.
• 2-4 Weeks: With consistent daily use and diligent sun protection, overall skin tone should start to look brighter and more radiant. The antioxidant effects help protect the skin from daily environmental stressors.
• 4-8+ Weeks: The most significant changes to hyperpigmentation occur in this timeframe. Post-acne marks (PIH) and sun spots should begin to appear visibly lighter. Continued use helps maintain an even complexion and improves skin texture.

Individual results vary. Efficacy is highly dependent on consistent application and, most importantly, daily sunscreen use.

[Myth] "I can use lemon juice to fade my dark spots; it's natural and has Vitamin C."

[Truth] While lemons do contain Vitamin C, applying raw juice to your skin is a recipe for irritation. Lemon juice is highly acidic (pH ~2) and can cause chemical burns, disrupt your skin's protective barrier, and lead to phytophotodermatitis—a painful reaction when skin is exposed to the sun. This can worsen dark spots, not improve them.

[Why This, Not That] Choose a professionally formulated Vitamin C serum like this one instead. It's created at a specific pH (~3.5) that is effective for absorption but safe for skin. It's also stabilized with other ingredients like Ferulic Acid and Vitamin E to ensure the Vitamin C works effectively without causing the damage and photosensitivity associated with DIY citrus remedies.

• ✅ Works Well With:
  • Sunscreen: An essential pairing. Vitamin C boosts sunscreen's protective power.
  • Hyaluronic Acid, Snail Mucin, Panthenol: These hydrators help to soothe and plump the skin, complementing Vitamin C's effects.
  • Niacinamide: While a myth exists about them conflicting, modern formulations are generally fine to use together. For maximum benefit and minimal risk of flushing, you can use Vitamin C in the AM and Niacinamide in the PM.
  • Vitamin E & Ferulic Acid: These antioxidants are often formulated with Vitamin C to stabilize it and enhance its effects.
• ⚠️ Use with Caution:
  • AHAs & BHAs (Glycolic, Salicylic Acid): Using multiple acids in the same routine can lead to over-exfoliation and irritation. It's best to alternate their use (e.g., Vitamin C in the AM, AHA/BHA in the PM).
• 🚫 Avoid Using Together (in the same routine):
  • Retinol/Retinoids: Both are potent actives that can be irritating. Using them in the same routine increases the risk of sensitivity, redness, and peeling. Use Vitamin C in the AM and Retinol in the PM.
  • Benzoyl Peroxide: Can oxidize Vitamin C, making it less effective. Separate their use between morning and night.
  • Copper Peptides: Can potentially destabilize pure L-Ascorbic Acid. Use them in separate routines.

• Oily / Combination Skin: Excellent. The lightweight, watery texture absorbs quickly without adding grease, and Vitamin C can help with post-acne marks common in these skin types.
• Normal Skin: Ideal. Provides great antioxidant protection and helps maintain a bright, even complexion.
• Dry Skin: Good, but should be followed by a nourishing moisturiser. The serum provides brightening benefits but is not a primary hydrator.
• Sensitive Skin: Use with caution. The 5.5% concentration of pure L-Ascorbic Acid and its low pH can be too stimulating for highly reactive skin. A patch test is mandatory. Consider starting with a gentler Vitamin C derivative if your skin is very sensitive.

• Post-Inflammatory Hyperpigmentation (PIH) - The dark marks left behind after acne.
• Sun Spots & Freckles - Discoloration caused by sun exposure.
• Dull, Lackluster Skin - Improves overall brightness and glow.
• Uneven Skin Tone - Helps create a more uniform complexion.
• Environmental Damage - Provides antioxidant protection against free radicals from pollution and UV rays.

[Key Actives Explained]

• Ascorbic Acid (5.5%): The purest form of Vitamin C. A powerful antioxidant that inhibits melanin production to fade dark spots, protects against environmental damage, and helps stimulate collagen production. (Ingredient Rationale)
• Aronia Melanocarpa (Black Chokeberry) Fruit Extract: A potent antioxidant rich in anthocyanins, which helps stabilize the Vitamin C and protect the skin from free radical damage. (Ingredient Rationale)
• Ferulic Acid: A plant-based antioxidant that works synergistically with Vitamin C and E to boost their stability and photoprotective capabilities. (Ingredient Rationale)
• Tocopherol (Vitamin E): A lipid-soluble antioxidant that protects cell membranes and works with Vitamin C to provide comprehensive antioxidant defense. (Ingredient Rationale)
• Sodium Hyaluronate: A form of Hyaluronic Acid that draws moisture into the skin, providing lightweight hydration to keep the skin plump and balanced. (Ingredient Rationale)

[Full INCI List]

Aronia Melanocarpa Fruit Extract, Ascorbic Acid (5.5%), Butylene Glycol, Propanediol, Betaine, Tromethamine, Sodium Hyaluronate, Ferulic Acid, Allantoin, Tocopherol, Scutellaria Baicalensis Root Extract, Paeonia Suffruticosa Root Extract, Glycyrrhiza Glabra (Licorice) Root Extract, 1,2-Hexanediol, Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer, Isohexadecane, Polysorbate 80.

• Fragrance Status: No artificial fragrance added.
• Scent Profile: May have a faint, slightly metallic or savory scent, which is characteristic of serums containing Ferulic Acid and pure L-Ascorbic Acid. This scent is normal and dissipates quickly.
• EU Allergens: None declared by the brand based on the provided INCI list.

As with any product, especially one with potent actives, a patch test is highly recommended before first use.

[Who Should Use With Caution]

• Highly Sensitive or Rosacea-Prone Skin: The low pH and potency of pure Vitamin C can cause irritation. Start with a patch test.
• Damaged Skin Barrier: Do not use on broken, peeling, or compromised skin. Focus on barrier repair first.
• Pregnancy/Breastfeeding: Topical L-Ascorbic Acid is generally considered safe. However, it is always best to consult with your doctor before introducing new active ingredients during this time.

[Patch Test Protocol]

1. Apply a small, pea-sized amount of the serum to a clean, discreet area of skin, such as behind the ear or on the inner jawline.
2. Wait 24 hours to observe for any signs of irritation like excessive redness, burning, or a rash.
3. If no reaction occurs, the product is likely safe for you to use on your face. If irritation develops, discontinue use.

• Texture: A very lightweight, watery liquid serum.
• Finish: Absorbs quickly into the skin leaving a natural, slightly dewy finish. It is not oily or sticky when the correct amount is used.
• pH: Approximately 3.5 - 4.0. This low pH is necessary for the stability and optimal penetration of pure L-Ascorbic Acid.
• Fungal Acne (Malassezia) Compatibility: The formula appears to be suitable for those concerned with fungal acne, as it does not contain common triggers like fatty acids or esters. However, individual responses can vary.

• Issue: The serum feels sticky after application.
  Solution: You are likely using too much product. 2-3 drops is sufficient for the entire face. Ensure you are applying it to completely dry skin.
• Issue: I feel a tingling or warming sensation.
  Solution: A mild, temporary tingling is normal with potent L-Ascorbic Acid serums due to the low pH. It should fade within a minute. If it's a persistent burning sensation, wash the product off immediately.
• Issue: The serum has turned dark yellow or brown.
  Solution: The Vitamin C has oxidized and is no longer effective. Discard the bottle. To prevent this, store it tightly sealed in a cool, dark place like a cabinet or refrigerator, and aim to use it within 3 months of opening.
• Issue: My skin feels a bit dry after using it.
  Solution: This can happen with low-pH products. Ensure you are following up with a good hydrating toner or moisturiser to replenish moisture.

• Humid Summers: The lightweight, non-greasy texture is perfect for Mauritius's humid conditions. It provides antioxidant protection without feeling heavy or sticky.
• Drier Winters / AC Exposure: The serum itself is not deeply moisturizing. During drier periods or if you spend a lot of time in air-conditioning, be sure to layer a hydrating moisturiser on top to prevent dehydration.
• Storage Warning: The heat and light in Mauritius can accelerate the oxidation of Vitamin C. It is highly recommended to store this serum in its box, in a cool cabinet away from windows, or ideally, in the refrigerator to prolong its potency.

• Ingredient Rationale: The combination of Vitamin C with Vitamin E and Ferulic Acid is a well-established synergy in cosmetic science, shown to significantly enhance the stability and antioxidant capacity of the formula, providing superior protection against UV-induced damage compared to Vitamin C alone.

Aggregated sentiment from online beauty communities. Note: Individual experiences may vary.

"This is my holy grail for post-acne marks! I've been using it every morning for about 6 weeks, and the brown spots on my cheeks are definitely lighter. It gives my skin a really nice, healthy glow under my sunscreen."

— Paraphrased from Reddit, r/AsianBeauty (thread 2024-09)

"It tingles a little bit when I apply it, but it goes away fast. I love how watery it is, it sinks in so quickly and doesn't feel sticky at all, which is great for my oily skin. My overall complexion looks brighter."

— Paraphrased from a YesStyle review (2025-01)

Fair Caveat: "You have to be patient with this one. I didn't see a huge difference in my darker sun spots for nearly two months. Also, you MUST store it in the fridge. My first bottle turned yellow in about 8 weeks because I left it in my bathroom."

— Paraphrased from an Amazon customer review (2024-11)

Jumiso is a Korean skincare brand that believes in making skincare simple, effective, and enjoyable.

Antioxidant

A molecule that protects the skin from damage caused by free radicals, which are unstable atoms generated by things like UV rays and pollution.

PIH (Post-Inflammatory Hyperpigmentation)

The dark spots or marks left on the skin after a pimple, wound, or other irritation has healed. It is caused by an overproduction of melanin.

Why does this Vitamin C serum tingle?

A mild tingling sensation is normal for serums with a high concentration of pure L-Ascorbic Acid due to its low pH. This indicates the product is active. The sensation should be brief. If it persists or feels like burning, wash it off.

Can I use this serum if it has turned yellow?

No. A significant color change to yellow or orange means the L-Ascorbic Acid has oxidized and is no longer effective. It may even cause irritation. It's best to discard it.

Can I use this with my Niacinamide serum?

Yes. While there are myths about them conflicting, modern formulations are generally stable. To be extra safe and maximize benefits, you can use the Vitamin C serum in your AM routine and the Niacinamide serum in your PM routine.

How is this different from other Vitamin C serums?

This serum uses 5.5% pure L-Ascorbic Acid, the most researched form of Vitamin C, for potent results. It is also formulated with antioxidants like Aronia Extract, Vitamin E, and Ferulic Acid to enhance its stability and protective power, all in a lightweight, non-sticky base suitable for many skin types.
