The Medicube Collagen Glow Booster Milk Serum is a lightweight, milk-textured serum formulated with niacinamide, milk protein extract, and hydrolyzed collagen. It is designed to support skin radiance and hydration while promoting a firmer appearance. This product is part of the Korean skincare range from Medicube and comes in a 0.50 oz (15 ml) size with a Twist & Click mechanism that dispenses a measured amount of serum with each turn, minimizing waste and maintaining hygiene.

The serum targets dullness and dehydration by delivering moisture and brightening benefits. Niacinamide, a well-recognized ingredient for improving uneven skin tone, works alongside milk protein extract to reinforce the skin’s moisture barrier. Hydrolyzed collagen, broken down into smaller peptides, is included to help support the skin’s firmness and elasticity over regular use. The milky consistency absorbs without leaving a sticky residue, making it suitable for layering under moisturizers or sunscreen.

This product is intended for those seeking a gentle, non-irritating addition to their daily skincare routine. It can be used by individuals with normal, dry, combination, or sensitive skin types who want to enhance luminosity and maintain a plumped look. The formula is free from artificial fragrances and excessive additives, focusing on hydration and skin conditioning.

For best results, apply one to two twists of the serum onto clean, toned skin in the morning and evening. Gently pat the milk-like formula into the face and neck until fully absorbed. Follow with a moisturizer or sunscreen as needed. Avoid contact with eyes and discontinue use if irritation occurs. Store in a cool, dry place away from direct sunlight. As with any cosmetic product, conduct a patch test before first use if the skin is sensitive.
