House of B Glutathione Overnight 2-Step Collagen Hydrogel Face Mask — Clear Film & 99% Glutathione for Hydration, Radiance

This Korean-style overnight treatment combines a potent 99% high-purity glutathione ampoule with a transparent collagen hydrogel film to create a sealed moisture barrier while you sleep. The system is engineered to deliver ingredients more effectively: a skin-fit wrap keeps serum in direct contact with the skin and limits loss to evaporation. It’s designed for nights when you want a refreshed, luminous complexion quickly—before events, photos, travel, or any time dull or tired skin needs a targeted boost.

How does the two-step system work while I sleep?

The routine is simple: apply the concentrated glutathione ampoule first, then place the ultra-thin collagen hydrogel film over top to seal the serum in. The film’s 1.8mm flexible design adheres closely to the contours of the face, preventing sliding and helping ingredients stay in contact with the skin through the night. As a result, the ampoule’s actives remain concentrated where they’re needed.

• Step 1: Dispense ampoule and pat across target areas; lightweight formula absorbs quickly.
• Step 2: Apply the clear hydrogel film to lock in moisture and reduce evaporation.
• Film fits facial curves to maintain contact and comfort for overnight wear.

What key ingredients are included and what do they target?

The formula centers on 99% high-purity glutathione combined with niacinamide, adenosine, L-cysteine and an amino acid complex. These ingredients are selected to address common cosmetic concerns such as the appearance of dullness, uneven tone, and fine lines, while supporting a more even, luminous surface appearance. The combination focuses on surface texture, radiance, and perceived firmness rather than clinical claims.

• 99% high-purity glutathione: concentrated antioxidant-supporting agent for brighter-looking skin tone.
• Niacinamide: helps visibly even skin tone and refine texture.
• Adenosine and amino acids: support smoothing of fine lines and healthier-looking skin surface.

Will the hydrogel film feel comfortable overnight and is it safe for sensitive skin?

The collagen hydrogel film is engineered for long-wear comfort with a low-irritation profile from dermatological testing. It is formulated to remain hydrated and comfortable through extended use without drying out, and underwent a 24-hour patch evaluation with an excellent non-irritating score. As always, perform a small-area patch test if you have highly reactive skin or known sensitivities.

• Ultra-thin, flexible 1.8mm film minimizes movement and friction during sleep.
• 24-hour low-irritation tested; classified as non-irritating in dermatological evaluation.
• Designed to maintain moisture balance and comfort overnight.

How will repeated use affect pores and firmness?

Regular use is intended to help the appearance of pore laxity and skin firmness by supporting surface hydration and texture refinement. The mask’s sealing action helps the ampoule ingredients remain concentrated at the surface where they can support a plumper, more refined look over time. Individual results vary based on skin type and frequency of use.

• Hydration and film-sealing can make pores appear less pronounced temporarily.
• Ingredients like niacinamide and amino acids help with visible texture and elasticity over continued use.
• Best used before events or consistently as part of an occasional overnight treatment routine.

Who is this for: HOUSE OF B High-Purity Glutathione Face Film is suited for people who want a targeted overnight treatment to revive dull, tired-looking skin before special occasions or as part of a routine boost. It’s ideal for those seeking a non-invasive, Korean-inspired moisture wrap to improve surface radiance, refine texture, and support a smoother-looking complexion. If you have sensitive or reactive skin, consider a patch test first.
