SUNGBOON EDITOR Deep Collagen Overnight Mask 4 Count

Overview

Sungboon Editor's Deep Collagen Overnight Mask is a Korean sheet mask sold in a 4-count pack, marketed around a high-concentration collagen and peptide blend for hydration, firming and pore refining.

The product name leads with a large collagen figure and 9 peptides, though the ingredient data provided lists hyaluronic acid as the active ingredient, so buyers should treat the collagen and peptide figures as brand marketing rather than confirmed lab specs. It's an overnight sheet mask format, meant to sit on skin longer than a standard 15 to 20 minute mask. The cruelty-free labeling and focus on elasticity and hydration fit the broader K-beauty overnight mask category.

• Overnight sheet mask, 4 count
• Hyaluronic acid active ingredient
• Marketed collagen and peptide blend
• Cruelty-free formula

Who it's for

Fits people already using Korean skincare routines who want an overnight sheet mask for hydration and firming. Less suited to anyone wanting a single, clearly-dosed active ingredient rather than a proprietary blend.

Pros and cons

Performance notes

Hyaluronic acid is a well-established humectant that draws moisture into the skin, supporting the hydrating and radiant-skin claims. Overnight masks are designed for extended wear rather than a quick rinse-off, giving actives more contact time with skin, though the trade-off is a stickier feel overnight. Firming and elasticity claims are harder to verify from the ingredient data alone since only hyaluronic acid is itemized as an active.
