Description

Technical Field

[0001] This invention relates to the field of cosmetic technology, specifically to a nighttime serum formula and preparation method for brightening and repairing skin after staying up late. Background Technology

[0002] Prolonged sleep deprivation can damage the skin barrier, lead to collagen loss, free radical accumulation, and disrupt melanin metabolism, resulting in dullness, roughness, and increased fine lines. Most serums on the market offer single-function benefits (such as moisturizing or whitening) and lack a multi-functional synergistic repair mechanism specifically for skin damaged by sleep deprivation. Furthermore, traditional serums often contain high concentrations of alcohol or fragrances, which may irritate sensitive skin, and some active ingredients (such as vitamin C) are unstable and prone to oxidation and degradation. Therefore, there is an urgent need for a safe and effective nighttime serum formula that, through the synergistic effect of multiple components, achieves deep repair and brightening of skin damaged by sleep deprivation.
