Struggling with stubborn dark spots, post-acne marks, or a dull complexion from sun exposure in Mauritius? This is your intensive weekly reset.

This potent sheet mask is soaked in the equivalent of a full bottle of Goodal's famous Green Tangerine Vita C Serum. It delivers a concentrated dose of Niacinamide and Vitamin C derivatives directly to your skin, working to visibly fade hyperpigmentation and restore a bright, even-toned glow. Its lightweight, hydrating formula is perfect for all skin types seeking a powerful brightening treatment without heaviness.

1. Cleanse: Start with a clean face to ensure maximum serum absorption.
2. THIS PRODUCT (10-20 mins): Apply the sheet mask and relax. After removing, pat the remaining serum into your skin.
3. Moisturise (PM): Follow with your favourite moisturiser to seal in the brightening serum.

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

While best suited for evening use, this mask can be used in the morning for an intense brightening and hydration boost before a special event.

• 1) Cleanser: Wash your face gently.
• 2) Toner (Optional): Apply a hydrating toner to prep the skin.
• 3) THIS PRODUCT (10 mins): Apply the sheet mask for a shorter duration. Remove and pat in the excess serum.
• 4) Moisturiser: Apply a light layer to lock in hydration.
• 5) Sunscreen SPF 30+: Absolutely essential. This protects your skin from new dark spots and ensures the mask's benefits aren't undone by UV damage.

Wait times: Allow the serum from the mask to absorb for 1-2 minutes before applying moisturiser and sunscreen to prevent pilling.

Using this mask at night allows the potent serum to work undisturbed during your skin's natural repair cycle.

• 1) Double Cleanse: Start with an oil cleanser to dissolve sunscreen and makeup, followed by a water-based cleanser.
• 2) Toner: Apply a hydrating or balancing toner.
• 3) THIS PRODUCT (10-20 mins): Unfold and apply the sheet mask. Relax and let the serum work.
• 4) Serum Application: After removing the mask, gently pat the rich remaining serum into your face, neck, and even the backs of your hands. Do not rinse.
• 5) Eye Cream (Optional): Apply your eye cream.
• 6) Moisturiser: Finish with a moisturiser to create a protective barrier and lock in all the active ingredients overnight.

• Amount: One full sheet mask per use.
• Apply to: A clean, toned face. Carefully align the eye, nose, and mouth openings.
• Method: Smooth the mask over your face, ensuring good contact. After 10-20 minutes, remove the mask and gently pat the leftover serum into your skin until absorbed. Don't waste the extra serum in the packet—apply it to your neck, chest, and arms!
• Frequency: Use 1-3 times per week as an intensive treatment for dark spots and dullness.

If-This / Then-That:

• Very oily skin? You might find the serum hydrating enough to use a very lightweight gel moisturiser on top.
• Very dry skin? Follow up with a richer, more occlusive cream to prevent moisture loss.
• Sensitive skin? Start by using the mask for just 10 minutes to assess tolerance. A slight tingle can be normal with Vitamin C, but remove immediately if it burns.
• Using Retinoids? It's best to alternate nights. Use this mask on nights you are not using your retinoid to avoid potential irritation.

Watchouts: A sticky feeling means you need to pat the serum in for longer, or you might have too much on your skin. If pilling occurs under your moisturiser, wait longer for the serum to fully absorb before the next step.

Safety: For external use only. Avoid contact with eyes. Discontinue use if a rash or irritation occurs. Do not use on broken or damaged skin.

Integrate this mask as a targeted treatment 1-3 times per week on your "brightening" nights.

Example Weekly PM Routine:

• Mon: Hydration & Barrier Support Night (no strong actives)
• Tue: THIS PRODUCT (Brightening Night)
• Wed: Exfoliation Night (e.g., a gentle AHA/BHA toner)
• Thu: Hydration & Barrier Support Night
• Fri: THIS PRODUCT (Brightening Night)
• Sat: Retinoid Night (if in your routine)
• Sun: Soothing & Recovery Night (e.g., a calming sleeping pack)

Rule: It's best not to use this mask on the same night as a strong exfoliant or retinoid, especially if you have sensitive skin, to minimise the risk of irritation.

Mauritius Note: After a long day in the sun, this mask can feel incredibly refreshing and helps combat oxidative stress from UV exposure. For an extra cooling effect, store it in the fridge for 10 minutes before use.

• Immediate: Skin feels deeply hydrated, plump, and has an instant, radiant glow. Redness may appear slightly calmed.
• After 2-4 Weeks (with 2-3x weekly use): Skin tone begins to look more even and brighter. Overall complexion appears less dull and more vibrant.
• After 4-8+ Weeks: Visible reduction in the appearance of recent dark spots, post-acne marks, and sun spots. Continued use alongside daily sunscreen helps maintain a clearer, more luminous complexion.

Why use THIS, not pure lemon juice?

While lemons contain Vitamin C, applying raw lemon juice to your skin is a bad idea. Its very low pH can severely irritate and damage your skin barrier. Worse, it contains compounds that can cause a chemical burn or lasting dark spots when exposed to sunlight (phytophotodermatitis). This mask delivers a stable, pH-balanced dose of Vitamin C and other brightening ingredients that are scientifically formulated to be effective and much safer for your skin.

• Works Well With:
  • Niacinamide: A great partner for brightening. Using a niacinamide serum on alternate days can enhance the spot-fading results.
  • Hyaluronic Acid: Layering a hyaluronic acid toner before the mask will boost hydration, making skin plump and dewy.
  • Sunscreen: Non-negotiable. Sunscreen is essential every morning to protect your progress and prevent new spots from forming.
  • Gentle Moisturisers: Following the mask with a ceramide or panthenol-based moisturiser helps lock in the serum and support your skin barrier.
• Use With Caution:
  • Retinoids (Retinol, Retinal): Avoid using on the same night to prevent potential over-stimulation and irritation. Alternate nights for best results.
  • High-Strength AHAs/BHAs: Using a strong chemical exfoliant on the same night can lead to sensitivity. If you use a peel or strong acid serum, use this mask on a different day.

• Oily & Combination Skin: Excellent. The serum is lightweight and absorbs well, providing brightening and hydration without feeling greasy.
• Dry & Dehydrated Skin: Very good. The mask provides a significant hydration boost. It is crucial to follow up with a good occlusive moisturiser to seal in all the benefits.
• Normal Skin: Ideal for maintaining a bright, even tone and providing a weekly radiance boost.
• Sensitive Skin: Use with caution. The formula contains Vitamin C and several essential oils which can be potential irritants for highly reactive skin. A patch test is strongly recommended. Start with a shorter application time (10 minutes).

Key Actives Explained:

• Niacinamide (Vitamin B3): A superstar ingredient that helps to visibly improve the appearance of enlarged pores, uneven skin tone, and a weakened skin surface. It also has anti-inflammatory properties and helps inhibit the transfer of melanin, which is key to fading dark spots.
• Citrus Tangerina (Tangerine) Extract: Sourced from green tangerines, this extract is rich in natural Vitamin C derivatives and antioxidants. It helps to revitalize dull skin and provides a brightening effect.
• Arbutin & Ascorbyl Glucoside: Two powerful and stable brightening agents. Arbutin is a derivative of hydroquinone that works by inhibiting tyrosinase, the enzyme responsible for melanin production. Ascorbyl Glucoside is a stable form of Vitamin C that converts to pure Vitamin C on the skin, providing antioxidant and brightening benefits with less irritation.
• Ascorbic Acid (Pure Vitamin C): A potent antioxidant that helps protect the skin from free radical damage, boosts collagen production, and brightens the complexion.
• Adenosine: A cell-communicating ingredient known for its anti-wrinkle benefits. It energizes the skin's surface, leading to a smoother, more youthful appearance.

Who should use this?

Anyone looking for an intensive treatment to fade dark spots and boost skin radiance. It is suitable for most skin types, but caution is advised for very sensitive skin.

Who should use with caution?

• Highly Sensitive Skin: The presence of Vitamin C and multiple essential oils may cause irritation.
• Pregnancy/Breastfeeding: Contains essential oils. While generally considered safe in the low concentrations found in skincare, it is always best to consult with your doctor before introducing new products during pregnancy or breastfeeding.

Patch Test Protocol:

Before using the mask on your face, test for sensitivity. Squeeze a small amount of serum from the packet onto a clean patch of skin, such as the jawline or behind the ear. Wait 24 hours. If no redness, itching, or burning occurs, it is likely safe to use on your face. Re-check at 48 and 72 hours for any delayed reaction.

If irritation occurs: Immediately remove the mask and rinse your face with cool water. Apply a simple, soothing moisturiser. Discontinue use.

• Texture: A soft, microfilament fiber sheet mask generously soaked in a lightweight, slightly viscous, gel-like serum.
• Finish: The skin feels very hydrated and dewy after use. There may be a slightly tacky finish until the serum fully absorbs.
• Scent: A refreshing, natural citrus scent from green tangerine and other essential oils.
• pH (Estimated): ~5.5 - 6.5. Formulated to be close to the skin's natural pH for gentleness.
• Fungal Acne (Malassezia) Compatibility: This product contains Polyglyceryl-10 Laurate, which can be a potential trigger for some individuals with fungal acne. Individual responses may vary, and a patch test on an affected area is advised.

• Issue: The mask feels tingly or slightly warm.
  • Quick Fix: A mild tingling sensation can be normal, especially for skin new to Vitamin C. However, if it progresses to burning or discomfort, remove the mask immediately and rinse your face.
• Issue: My skin feels sticky after using the mask.
  • Quick Fix: This means there is a lot of rich serum on your skin. Continue to gently pat the serum for another 1-2 minutes until it is better absorbed. If it still feels heavy, you can use a slightly lighter moisturiser on top.
• Issue: I don't see my dark spots fading after one use.
  • Quick Fix: Fading hyperpigmentation is a marathon, not a sprint. A sheet mask provides an intensive boost, but consistent, long-term care (including daily sunscreen) is required to see significant results over several weeks to months.

This sheet mask is an excellent choice for the Mauritian climate.

• Humid Summers: The lightweight serum provides intense hydration and brightening without feeling heavy or greasy. It's a perfect refreshing treatment after a day in the heat and sun. Storing it in the refrigerator for 10-15 minutes before use provides an amazing cooling and de-puffing effect.
• Drier Winters / AC Exposure: The hydrating properties of the serum help combat the dryness caused by indoor air conditioning or the slightly less humid winter air. Be sure to follow up with a good moisturiser to lock everything in.
• Sun Exposure: Given the high UV index in Mauritius, this mask is a great addition to a routine focused on preventing and treating sun-induced pigmentation. It helps fight the oxidative stress caused by sun exposure, but it is not a replacement for daily sunscreen.

• Format: A single-use sheet mask in a foil-lined plastic packet (28g).
• Hygiene: The single-use format is highly hygienic.
• Recycling (Mauritius): The outer packet is typically made of mixed materials (plastic/foil) and may not be easily recyclable in local municipal streams. Please dispose of it thoughtfully in the trash.
• Storage: Store in a cool, dry place away from direct sunlight. For an extra cooling and de-puffing effect, you can store it in the refrigerator.
• Travel: The flat, single-use packet is extremely travel-friendly.

Note: These are aggregated sentiments from online communities and do not guarantee individual results.

• On Hydration and Glow: Many users praise the immediate effects of the mask. One reviewer on Reddit (r/AsianBeauty, 2021-02) noted their skin felt "moisturized and not tight" right after use, although they disliked the slightly sticky finish.

• On the Serum Content: A common point of praise is the generous amount of serum in the packet. Users often mention using the excess on their neck, chest, and arms, adding to the value of the single-use mask.

• On Dark Spot Efficacy (Caveat): While the mask provides an instant glow, some users are skeptical about its long-term dark spot fading abilities from occasional use alone. A Reddit review (2025-01) mentioned that while highly moisturizing, they "didn't see much of an effect on fading dark spots" and wouldn't recommend it if that is the sole goal, suggesting the daily serum might be better for consistent treatment.

• On Fit and Scent: The mask fit is generally considered good, adhering well to the face without sliding. The citrus fragrance is frequently described as "refreshing" and pleasant, though it can linger for a short while after removal, which might be a consideration for those sensitive to scents.

Niacinamide

A form of Vitamin B3, a multi-functional ingredient that helps with brightening, sebum control, and strengthening the skin barrier.

Vitamin C

A powerful antioxidant that protects skin from environmental damage, brightens skin tone, and promotes collagen production. This mask uses both pure Ascorbic Acid and a stable derivative, Ascorbyl Glucoside.

PIH (Post-Inflammatory Hyperpigmentation)

The dark marks or spots left behind after a pimple, cut, or other skin inflammation has healed. This is a primary target for this mask.

Sheet Mask

A single-use face-shaped sheet, typically made of fiber, soaked in a concentrated serum. It works by creating a temporary barrier that forces the skin to absorb the serum's active ingredients.

Our product descriptions are based on diligent research and a beginner-first mindset, aimed at protecting and informing you, our valued customer. We prioritize your skin's health over hype.

Will this mask sting or irritate my skin?

It's possible. Vitamin C and essential oils can cause a tingling sensation, especially on sensitive skin. If you experience burning or strong discomfort, remove the mask immediately. A patch test is always recommended.

Do I need to rinse my face after using the mask?

No, do not rinse. The leftover serum is the most concentrated part of the treatment. Gently pat it into your skin until absorbed to get the full benefits, then follow with a moisturiser.

Can I use this mask if I have acne?

Yes, it can be very beneficial for fading the dark marks (PIH) that acne leaves behind. However, be cautious using it over active, open, or inflamed breakouts as it could cause stinging.

Is one mask enough to see results?

You will see immediate results in hydration and glow after one use. However, for visible fading of dark spots, consistent use over several weeks (e.g., 1-3 times per week) is necessary, combined with daily sunscreen use.

• Best For: Those seeking an intensive treatment to kickstart the fading of dark spots and achieve an immediate, dewy radiance.
• Key Benefits: Delivers a high concentration of Vitamin C and Niacinamide; instantly hydrates and brightens the complexion.
• Keep in Mind: Contains essential oils, which may not be suitable for extremely sensitive skin. Fading dark spots requires consistent use over time and diligent sun protection; this mask is a powerful booster, not a one-time cure.
