Today, with the rapid development of Yan value economy, oral beauty products are gradually emerging and become a new choice for consumers to pursue beauty. Today we will talk about what is collagen peptide? Is collagen peptide safe and effective?

Collagen peptide is a kind of functional peptide with triple helix structure and composed of 2-20 amino acid residues short sequence, which is made of collagen protein after enzymatic hydrolysis and thermal hydrolysis. Compared with collagen, the average molecular weight is about 300-20000Da, and the absorption rate can exceed 90%.

According to the White Paper on the Development of the Domestic high quality Collagen Industry issued by the Institute of International Trade and Economic Cooperation of the Ministry of Commerce, collagen peptides can supplement skin nutrition, remove skin wrinkles, delay aging, moisturize and whiten, repair damaged skin, and enhance human immunity. Its nutritional value and application efficacy are far better than collagen.

The role of collagen peptides in maintaining skin moisture and improving skin photodamage has also been supported by a number of clinical trials. A clinical trial carried out in Koizumi et al. studied the effect of fish bone collagen peptide on female skin. Female subjects aged 30-60 took 3g of collagen peptide orally every day for 12 weeks, and found that periorbital wrinkles were reduced, facial skin moisture content and skin elasticity were significantly increased, and there were no side effects and toxic effects;

Asserin et al. found that Japanese women aged 40-59 and white women aged 40-65 who ate 10g of fish collagen peptide every day increased the density of collagen in the dermis of the subjects in the 4th week, decreased fragmentation, and significantly increased skin water content in the 8th week.

According to the data, the market size of China's oral beauty industry will reach 23.8 billion yuan in 2022, and the market size is expected to exceed 25.57 billion yuan by 2025. In the face of numerous collagen peptide products on the market, experts advise consumers to remain rational, pay attention to the source of raw materials, molecular weight, and addition amount, and preferably focus on scientific research, technology, and large brands with high sales.
