Take the skin test and I'll show you how suitable this product is for you.
Take the skin testThe ISOI Brightening Mask Sheet is a radiance-enhancing treatment designed to visibly improve skin tone, boost hydration, and restore a healthy glow. Infused with naturally derived brightening ingredients, this sheet mask helps reduce dullness and promote a clearer, more luminous complexion. Its soft, skin-adhering sheet ensures even delivery of essence for optimal absorption. Ideal for revitalizing tired or uneven skin, this mask helps smooth texture while providing soothing moisture. With continued use, the Isoi Brightening Mask Sheet leaves the skin looking brighter, refreshed, and visibly more radiant.
Brightening Mask Sheet is a lightweight sheet mask from ISOI. The formula is built mainly around hydration. The ingredient list runs to 32 ingredients, each broken down in full below.
By its ingredient list the formula reads as light: water and humectants lead, with emollients kept lower in the order. Hydration is handled by Betaine, Panthenol and Butylene Glycol, humectants that pull water into the upper layers of skin rather than sealing it there.
Hydration: High. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Betaine, Panthenol, Butylene Glycol and Water.
Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Panthenol, Chamomilla Recutita (matricaria) Flower Juice, Centella Asiatica Extract and Calendula Officinalis Flower Extract.
Brightening: Moderate. Ingredients that act on uneven tone and post-inflammatory marks, and here that comes from Arbutinyl Undecylenate, Glycyrrhiza Glabra Root Extract and Scutellaria Baicalensis Root Extract.
On richness alone it suits Balanced skin best, and is the least natural fit for Dry and Combination (dry) skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.
The formula contributes little or nothing on antioxidant protection, oil control, cell renewal and firmness signalling. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it.
Reading the full list, the formula is paraben-free, silicone-free, microplastic-free, sulfate-free, dye-free and oil-free. Those claims come from the ingredient list itself, not from the packaging. It does contain fragrance, essential oils and drying alcohol, worth knowing if your skin reacts to any of them.
It can be used morning and evening. In a routine it goes after serums. Seal in your serums with it; in the morning, sunscreen still goes on top.
This summary is generated from the product's ingredient list. It is not a review, it is not the brand's own marketing claims, and it does not replace advice from a dermatologist.
