Zeroid Soothing Serum Mask 5ea

Hydration Barrier Relief Mask for Extremely Sensitive Skin

A serum mask designed for sensitive skin that reacts easily to external stressors. Formulated with 19 types of NMF (Natural Moisturizing Factor) components that mirror the structure of skin's own moisture-binding elements, it helps care for a weakened protective barrier. Clinical testing showed that just one use improved redness on irritated skin by 3.4 times, reduced transepidermal water loss by 4 times, and increased stratum corneum hydration by 23.5%.

Skin-Compatible NMF Complex

Formulated with only highly skin-compatible ingredients to support sensitive skin with elevated pH and a compromised protective barrier. Amino acid-based hydrators including Sodium PCA (moisture binding) and Sodium Lactate (moisture retention) replenish skin's hydration reserves. After 4 weeks of use, skin sensitivity improved by 26.6%. The comfort-fit gauze sheet holds a generous amount of essence for long-lasting moisture and a seamless, comfortable fit.

Gentle Formula for Daily Use Without Worry

Completed suitability testing for sensitive skin and skin irritation testing. Recommended for skin that reacts and flares easily, experiences frequent temporary redness, or feels like its barrier has collapsed due to inner dryness. After cleansing, prep skin with toner, then apply the mask closely to the face. Remove after 10 to 20 minutes and gently pat in any remaining essence.

Use right after cleansing, when skin is most vulnerable

Apply immediately after cleansing, when skin tends to feel tight or flushed, to maximize the soothing effect. Prep skin lightly with toner to smooth texture, then press the mask into place. Also ideal for calming irritated skin after outdoor exposure or during seasonal sensitivity flare-ups.

Leave on for 10–20 minutes, then press in remaining essence

Unfold the mask and smooth it evenly over your face, then relax for 10–20 minutes. The 100% rayon gauze sheet is breathable, so it feels comfortable and never suffocating. After removing the mask, gently press any remaining essence into skin with your palms until fully absorbed.

How to use based on skin condition

• Temporary redness: Clinical results show redness improved 3.4 times after just one use. For an extra cooling effect, store the mask in the fridge before applying
• Dehydrated skin days: Clinical data shows a 23.5% improvement in skin moisture levels. After masking, follow with a soothing lotion or cream to lock in hydration
• Ongoing sensitivity care: Skin sensitivity improved by 26.6% after 4 weeks of use. Try incorporating it into your routine 2–3 times a week

Even better when paired with the Soothing line

Build a routine with the matching Soothing Lotion and Soothing Cream to enhance care for sensitive skin. Formulated with 19 types of NMF (including sodium PCA, sodium lactate, and glycine—ingredients that mimic skin's natural moisturizing factors), this approach works best when you use the mask for intensive calming, then seal in moisture with lotion and cream.

Storage and usage notes

Store in a cool place away from direct sunlight, and use immediately after opening. If any irritation occurs during use, remove the mask right away and rinse with water. Dermatologist-tested for sensitive skin and hypoallergenic-tested, so it's safe for even reactive skin types.
