      Product Detail  


    Peptides are small molecules that lie between amino acids and proteins. They have a smaller molecular weight and do not require decomposition. They can be directly absorbed and utilized by the human body, with a much higher utilization rate than ordinary proteins.
    The peptide products available on the market have undergone process purification to remove large molecular impurities, making them suitable for daily body supplementation. As people age, their body's ability to synthesize peptides decreases, leading to problems such as skin sagging, slowed metabolism, and reduced physical strength. Exogenous supplementation can fill the gap.
    Oral peptides can regulate the body's condition, repair internal cells, improve sleep quality, regulate basal metabolism, and help maintain energy; topical skin care peptides can soothe fine lines, firm the skin texture, and repair the damaged skin barrier.
    This product is gentle in composition and suitable for most skin types, differentiating it from ordinary health supplements. By taking it in appropriate amounts on a daily basis, it can improve one's complexion from within and delay signs of aging. The peptides are absorbed quickly and cause little burden on the stomach. Whether for daily maintenance or for people who stay up late or have irregular sleep schedules, it is suitable as a long-term maintenance option to achieve a state improvement from the inside out.

    Peptides are mainly classified based on their molecular structure into large molecule polypeptides, small molecule oligopeptides, as well as dipeptides and tripeptides. According to their application directions, they can be further divided into two categories: cosmetic peptides and health-promoting active peptides.
    Health-promoting active peptides can be rapidly absorbed by the digestive system and participate in body metabolism. They can repair body cells, regulate immunity, alleviate fatigue and weakness, as well as regulate blood sugar and lipid levels, nourish the stomach and intestines, repair the mucosa, slow down the aging of body functions, and are suitable for the daily treatment of people with sub-health conditions.
    The cosmetic peptides are mainly used in the field of skin care. Common ones include copper peptides and signal peptides, etc. They can stimulate the production of collagen, reduce fine lines, tighten the skin, repair the damaged barrier, improve redness, reduce skin laxity, and delay facial aging.
    There are also functional peptides, including fat-reducing peptides and anti-aging peptides, which can regulate fat metabolism, inhibit the accumulation of excess fat, and improve the bloated condition of the body.
    The small molecule form does not require secondary decomposition and has a higher absorption efficiency than proteins. When taken orally daily, it can regulate the body, and when used externally, it can improve skin quality. By consistently supplementing, it can maintain a youthful state from within and is suitable for body and skin care for people of different age groups.
