At-a-Glance (30s) (who it's for, what to expect)
Struggling with the stubborn dark spots and dullness that Mauritius' sunny climate can leave behind? This intensive serum-soaked sheet mask is designed to deliver a powerful dose of brightening ingredients for an immediate radiance boost.
- What it is: A single-use sheet mask saturated with a potent brightening serum featuring Yuja Extract and Niacinamide.
- Who it's for: Ideal for those with dull, uneven skin tone, post-acne marks (PIH), and sun spots. Suitable for oily, combination, and normal skin types.
- What it does: Provides concentrated brightening care to help fade hyperpigmentation, deeply hydrates, and leaves skin with a luminous, "glass skin" glow.
Quick Start (60-second routine) (essentials for beginners)
Use this mask 1-3 times per week as an intensive treatment, preferably in the evening.
- Cleanse: Start with a clean face to ensure maximum serum absorption.
- THIS MASK: Apply the sheet mask for 15-20 minutes. After removing, pat the remaining essence into the skin.
- Moisturise: Follow with a light moisturiser to seal in the benefits.
Mindful Note: On the night you use this mask, it replaces your regular treatment serum. No need to stack them.
How to Use (Beginner-friendly) (amount, frequency, and tips)
- Frequency: 1 to 3 times per week, as an intensive treatment in your PM routine.
- Amount: One single-use sheet mask.
- Step 1: Prep Skin: After cleansing and applying toner, carefully unfold the mask.
- Step 2: Apply Mask: Place the sheet evenly over your face, avoiding the eye and lip areas.
- Step 3: Relax: Leave on for 15-20 minutes. Don't leave it on until it's completely dry, as this can have a reverse-osmosis effect, pulling moisture from your skin.
- Step 4: Absorb: Remove the mask and gently pat the remaining serum into your face, neck, and chest until fully absorbed.
Pro-Tip for Mauritius Climate: For an extra cooling and de-puffing treat, store the mask in the refrigerator for 10-15 minutes before use. It's the perfect way to soothe overheated skin after a long day in the sun.
Weekly Planner (Example & Alternating Actives) (how to schedule use)
This mask is a treatment. To avoid over-stimulation, alternate its use with other strong actives.
Example PM Routine:
- Monday: Hydration & Barrier Repair (Gentle routine)
- Tuesday: Yuja Niacin Mask Night
- Wednesday: Hydration & Barrier Repair
- Thursday: Exfoliant Night (e.g., a gentle AHA/BHA toner)
- Friday: Hydration & Barrier Repair
- Saturday: Yuja Niacin Mask Night
- Sunday: Hydration & Barrier Repair
Rule of Thumb: Do not use this mask on the same night as strong retinoids or chemical exfoliants to prevent potential irritation.
What to Expect (Results Timeline) (immediate → 8+ weeks)
- Immediately After One Use: Skin will feel intensely hydrated, plump, and appear visibly brighter with a dewy glow. A perfect pick-me-up before an event. (Evidence: Ingredient Rationale)
- After 2-4 Weeks (using 2-3x weekly): Fresh post-acne marks may begin to look lighter. Overall skin tone appears more even and radiant. (Evidence: Ingredient Rationale)
- After 8+ Weeks: With consistent use alongside daily sun protection, older sun spots and more stubborn pigmentation may show noticeable improvement. Skin texture appears smoother and more refined. (Evidence: Brand test / Ingredient Rationale)

Myth Replacement (Why this, not that) (safer, effective alternatives)
Myth: "Applying raw lemon juice directly to dark spots is a good natural way to lighten them."
Truth: Raw lemon juice is highly acidic (pH ~2) and phototoxic. When exposed to sunlight, it can cause severe irritation, chemical burns, and even worsen hyperpigmentation (a condition called phytophotodermatitis). Instead of this risky DIY, use a professionally formulated product like the Yuja Niacin Mask. It delivers Vitamin C from Yuja extract in a stabilized, skin-safe serum combined with Niacinamide, offering a much safer and more effective path to a brighter, even complexion without the risk of burns or increased dark spots.
Compatibility Guide (layering) (what to pair it with)
- ✅ Works Well With: Hydrating ingredients like Hyaluronic Acid and Panthenol, soothing ingredients like Centella Asiatica, and gentle moisturisers. Most importantly, it must be paired with daily, high-SPF sunscreen to protect the brightening results.
- ⚠️ Use With Caution: Avoid using on the same night as other high-concentration actives like retinoids, AHAs, or BHAs to minimize the risk of over-stimulating the skin.
- ❌ Avoid On: Broken or irritated skin.
Skin Type Compatibility (best fits and cautions)
- Oily & Combination Skin: Excellent. Provides potent brightening and hydration in a lightweight, non-greasy format.
- Normal Skin: Excellent. A perfect weekly treatment to boost radiance and maintain an even tone.
- Dry Skin: Good. Delivers a surge of hydration and brightness. Be sure to follow with a nourishing moisturiser to lock in the essence.
- Sensitive Skin: Use with caution. The citrus extracts and fragrance may be too stimulating for highly reactive skin. A patch test is strongly recommended.
Targeted Concerns (what it helps to solve)
- Post-Inflammatory Hyperpigmentation (PIH) from acne
- Sun spots and freckles
- Dull, tired-looking complexion
- Uneven skin tone and texture

Complete Ingredient Transparency (key actives + full INCI)
Key Actives Explained:
- Citrus Junos (Yuja) Fruit Extract (10,000 ppm): Sourced from Goheung, Korea, this extract is naturally rich in Vitamin C, a powerful antioxidant that helps brighten the complexion, protect against environmental damage, and stimulate collagen.
- Niacinamide (2%): A form of Vitamin B3, this is the star MFDS-approved ingredient for brightening. It works by inhibiting the transfer of melanin (pigment) to the skin's surface, effectively fading dark spots and evening out skin tone. It also helps regulate sebum and strengthen the skin barrier.
- Glutathione & Arbutin: Powerful antioxidants that further support the brightening process by inhibiting the enzyme (tyrosinase) responsible for melanin production.
- Vitamin Complex: Includes Tocopherol (Vitamin E) and 3-O-Ethyl Ascorbic Acid (a stable Vitamin C derivative) to provide additional antioxidant protection and brightening synergy.
Full INCI List:
Water, Glycerin, Glycereth-26, Niacinamide (2%), Citrus Junos Fruit Extract (10,000 ppm), Methylpropanediol, 1,2-Hexanediol, Hydroxyacetophenone, Arginine, Acrylates/C10-30 Alkyl Acrylate Crosspolymer, Butylene Glycol, Hydroxyethylcellulose, Allantoin, Carbomer, Propanediol, Polyglyceryl-4 Caprate, Polyglyceryl-6 Caprylate, Adenosine, Ethylhexylglycerin, Disodium EDTA, Citrus Tangerina (Tangerine) Peel Oil, Coptis Japonica Root Extract, Citrus Paradisi (Grapefruit) Peel Oil, Panthenol, Tocopherol, Portulaca Oleracea Extract, Helianthus Annuus (Sunflower) Seed Oil, Pogostemon Cablin Oil, Cymbopogon Martini Oil, Arbutin, 3-O-Ethyl Ascorbic Acid, Tricholoma Matsutake Extract, Scutellaria Baicalensis Root Extract, Oryza Sativa (Rice) Extract, Angelica Keiskei Leaf/Stem Extract, Panax Ginseng Root Extract, Rosmarinus Officinalis (Rosemary) Leaf Extract, Hyaluronic Acid, Hydrolyzed Hyaluronic Acid, Sodium Hyaluronate, Glutathione, Limonene, Geraniol.
Allergens & Fragrance Disclosure (scent profile and potential irritants)
- Fragrance: Contains natural essential oils (Tangerine, Grapefruit, etc.) that give it a distinct, strong, and fresh citrus (Yuja) scent. Intensity: 4/5.
- EU Declared Allergens: This product contains Limonene and Geraniol, which are components of the essential oils used and must be declared for individuals with sensitivities.
Note: Due to the presence of citrus essential oils, a patch test is highly recommended, especially for those with sensitive skin or known citrus allergies.
Full Safety & Patch Test Protocol (important precautions)
- Who should use with caution: Individuals with very sensitive skin, active eczema, or known allergies to citrus fruits or essential oils.
- Patch Test Protocol: Before first use, apply a small amount of the essence from the packet to a discreet area of skin, such as behind the ear or on the inner jawline. Wait 24-48 hours. If no irritation (redness, itching, burning) occurs, it is likely safe to use on the face.
- General Safety: For external use only. Avoid contact with eyes. Discontinue use and consult a specialist if signs of irritation or rash appear. Keep out of reach of children.
- Teens: Suitable for teenagers dealing with post-acne marks, but should be integrated into a simple routine of cleanser, moisturiser, and daily sunscreen.
Sensory & Chemical Profile (texture, feel, and formulation)
- Texture: A soft, thin sheet made from 100% plant-based cellulose that adheres well to the skin. It is fully saturated in a lightweight, watery, slightly viscous serum.
- Finish: After removal, the remaining essence leaves the skin feeling deeply hydrated, plump, and looking very dewy and radiant. There may be a slight tacky feeling that subsides as the essence fully absorbs.
- Scent: A prominent and refreshing natural Yuja (citrus) aroma.
- pH: Not publicly disclosed by the brand, but expected to be in the skin-friendly range of 5.0 - 6.5.
Troubleshooting Guide (fix common issues) (quick solutions)
-
Issue: The mask feels tingly on my skin.
Solution: A very mild, brief tingle can be normal due to the Vitamin C from the Yuja extract, especially if your skin is not used to it. However, if it progresses to stinging or burning, remove the mask immediately and rinse your face with cool water. Your skin may be too sensitive for this product.
-
Issue: The essence feels sticky after I take the mask off.
Solution: This is common with hydrating sheet masks. Ensure you are gently patting, not rubbing, the essence until it is absorbed. If it still feels too heavy, you may only need a very light gel moisturiser on top, or none at all if your skin feels sufficiently hydrated (especially in Mauritius' humidity).
-
Issue: My skin looked brighter right after, but the effect didn't last.
Solution: The immediate glow is from intense hydration. The true brightening effects on pigmentation require consistent, long-term use (2-3 times a week for several weeks) combined with daily, non-negotiable sunscreen application to prevent new spots from forming.
Climate Fit for Mauritius (local usage advice)
- Humidity-Friendly: The lightweight serum texture absorbs well without feeling heavy or greasy, making it comfortable for our humid tropical climate.
- Post-Sun Soother: After a day outdoors, a refrigerated mask can provide immense cooling relief, calming down redness and replenishing lost hydration.
- Pigmentation Powerhouse: Hyperpigmentation from sun exposure and post-acne marks is a primary concern in Mauritius. This mask directly targets that with a potent blend of brightening ingredients. Remember, to see and maintain results, you MUST use a high-protection sunscreen like SPF 50+ PA++++ every single day.

Is This the Best Choice for You? (Mindful Alternatives) (other options to consider)
This mask is an excellent choice if your primary goal is intensive brightening for dark spots and dullness. However, your skin's needs can vary. Consider these alternatives from our catalog:
-
FOR SENSITIVE & IRRITATED SKIN: SOME BY MI REAL CICA CALMING CARE MASK 20G
Choose this if: Your skin is red, irritated, or too sensitive for citrus ingredients.
Why: It focuses purely on soothing and repairing with Centella Asiatica, calming inflammation without the stimulating effects of Vitamin C. -
FOR PORE & SEBUM CONCERNS: SOME BY MI REAL SUPER MATCHA PORE CARE MASK 20G
Choose this if: Enlarged pores, blackheads, and excess oil are your main frustrations.
Why: It uses Matcha and clay to purify pores and absorb sebum, providing a clarifying treatment rather than a brightening one. -
FOR A DIFFERENT FORMAT (WASH-OFF): AXIS-Y NEW SKIN RESOLUTION GEL MASK 100ML
Choose this if: You prefer a multi-use wash-off mask over a single-use sheet.
Why: This gel mask offers brightening with Niacinamide and soothing with Heartleaf in a tub format, allowing you to control the amount and frequency of use.
Mindful Use Reminder: If you already have a brightening mask or serum at home that you enjoy, consider finishing it before purchasing a new one. This helps reduce waste and gives you a clear understanding of what truly works for your skin.
Packaging, Sustainability & Practical Details (bottle, storage, and travel)
- Format: 25g of serum in a single-use foil packet containing one cellulose sheet mask.
- Sustainability: Sheet masks, by nature, are single-use items that generate more waste than bottled products. The outer packet is typically not recyclable in Mauritius. Please dispose of it thoughtfully in your regular trash.
- Travel: The flat, sealed packet is lightweight and perfect for travel, allowing you to bring an intensive spa treatment with you on the go.
Genuine Community Experiences (unbiased, real-user feedback)

"The glow is real! I used this before a wedding and my skin was so bright and plump, my makeup went on flawlessly. The smell is also amazing, like fresh yuzu."
"It definitely brightens and hydrates, but the essence is a bit sticky for my oily skin. I have to wait a while for it to sink in. Good for a night treatment but maybe too dewy for daytime."
"I love the whole Yuja Niacin line for my post-acne marks. Using this mask once a week really seems to speed up the fading process for new spots. My skin tone looks much more even."

Frequently Asked Questions (your questions, answered)
- Can I use this mask every day?
- It's designed as an intensive treatment, so using it 1-3 times per week is ideal. Daily use might be over-stimulating for some skin types and is not necessary to see results.
- Will this mask bleach or lighten my natural skin color?
- No. The "brightening" effect refers to fading hyperpigmentation like dark spots and sun damage to create a more even-toned complexion. It will not change your inherent, natural skin tone.
- The citrus scent is quite strong. Is that normal?
- Yes, the fresh and zesty Yuja scent is a signature characteristic of this entire product line, derived from the natural extracts and essential oils used in the formula.
- Can I use the leftover serum in the packet later?
- For hygiene reasons, it's best to use all the essence at the time of masking. You can apply the extra serum to your neck, chest, arms, and hands so nothing goes to waste!
