Collagen as a topical ingredient is debated: the molecule is too large to penetrate skin, so many experts dismiss topical collagen as marketing. However, modern formulations use hydrolyzed collagen (smaller fragments that can partially penetrate) and collagen-supporting peptides that stimulate the skin to produce its own collagen. medicube's Triple Collagen Serum 4.0 uses three collagen types plus supporting peptides for a comprehensive firming-focused serum.
"4.0" signals this is the fourth iteration of medicube's collagen formula, incorporating improvements over earlier versions. For mature skin users or those focused on firmness, this is a dedicated collagen-approach serum.
Three hydrolyzed collagen types provide surface plumping and skin softening. Collagen-stimulating peptides (e.g., palmitoyl tripeptide) signal the skin to produce its own collagen. Niacinamide supports tone correction. Over 8 to 12 weeks of daily use, expect improved skin firmness, reduced fine line appearance, and visible plumping.
After cleansing and toner, apply 3 to 4 drops. Pat until absorbed. Follow with moisturizer. Use AM and PM.
Hydrolyzed collagen provides mild surface plumping. Collagen-stimulating peptides work on the skin's own collagen production. Modern formulations are more effective than old-school collagen products.
