Is the real deep Glass Skin Mask safe for sensitive or acne‑prone skin?

The mask is free of common fragrances and includes soothing agents such as panthenol and allantoin, making it generally well‑tolerated for normal to dry skin, but the presence of polymers (Polyurethane‑35) and preservatives (1,2‑hexanediol, hydroxyacetophenone) could trigger irritation in highly sensitive or acne‑prone individuals, so a patch test is recommended.

What does niacinamide do in this sheet mask and why is it included?

Niacinamide (vitamin B3) helps improve the skin’s barrier function, reduces the appearance of hyperpigmentation, and regulates sebum production; its inclusion aims to brighten the complexion and support hydration alongside the DNA‑based actives.

How often should the mask be applied and are there any controversial ingredients to be aware of?

For best results, use the mask 2–3 times per week, leaving it on for 15–20 minutes; while most ingredients are typical for sheet masks, the formula contains PEG‑12 dimethicone, polysorbate 60 and 1,2‑hexanediol, which some consumers consider potentially sensitizing, so those with known sensitivities should monitor their skin’s response.

Product Insights

The real deep Glass Skin Mask in pink is a sheet mask formulated to deliver a brightening and hydrating treatment. Its formula combines water, glycerin, niacinamide, panthenol, sodium hyaluronate, allantoin and PDRN‑derived sodium DNA for moisture, barrier support and anti‑age benefits. However, it also contains synthetic polymers such as Polyurethane‑35 and PEG‑12 dimethicone plus preservatives like 1,2‑hexanediol and hydroxyacetophenone, which may irritate very sensitive skin and the vegan status is unclear.

Comparative Analysis

Positioned as a premium glass‑skin sheet mask targeting consumers seeking a brightening, DNA‑infused treatment, it differentiates itself with a blend of niacinamide, hyaluronic acid and PDRN alongside a polymer film base, while competing with other high‑end Korean‑style sheet masks.
