It’S SKIN Collagen Nutrition Serum is a 1.35 fl.oz (40 ml) nourishing face serum formulated with collagen and protein to support skin firmness and elasticity. The serum is designed to help smooth the appearance of fine lines while delivering hydration and a plumping effect to the skin. As part of a Korean skincare approach, this product focuses on replenishing collagen levels that naturally decline with age or environmental stress.

The key ingredient, collagen, is a structural protein known for its role in maintaining skin’s bounce and resilience. Paired with protein, the formula aims to reinforce the skin’s barrier and improve overall texture. The lightweight, non-greasy consistency allows for quick absorption, making it suitable for layering under moisturizers or makeup. It works well for normal, dry, combination, and mature skin types seeking additional support against visible signs of aging.

This serum is intended for daily use, applied after cleansing and toning, and before a moisturizer. It can be used as part of a morning or nighttime routine. The product is free from artificial dyes and strong fragrances, which may benefit those with sensitive skin when patch tested first. The 1.35 fl.oz size offers a practical amount for regular application over several weeks.

With a focus on core skincare benefits rather than dramatic claims, It’S SKIN Collagen Nutrition Serum provides a straightforward option for individuals looking to incorporate collagen-based nourishment into their regimen. The formula is manufactured in Korea, reflecting the brand’s emphasis on accessible yet efficacious skincare solutions.
