Collagen is one of the most widely used biological materials with a high degree of safety and biocompatibility, and has been used in facial plastic injections for over 30 years of safe application. Shuangmei 1 is the first collagen implant for injection that has passed the strict audit and been approved for marketing by SFDA in China, and it is also authoritatively certified by CE of EU and TFDA of Taiwan. Shuangmei No.1 collagen adopts the world’s advanced green, natural collagen purification and cross-linking technology, and its biological characteristics are basically the same as human collagen, reaching 99.9%, which is highly safe in use. Double beauty 1 is currently the best collagen in China. The indications of double beauty No.1 collagen: (1) face shaping: such as nasal bridge enhancement and nose transformation, chin augmentation, lip augmentation, earlobe augmentation, temporal augmentation, temple augmentation, etc. (2) Facial wrinkle removal: such as head-lift lines, inter-brow lines, tear trough lines, crow’s feet, decree lines (nasolabial folds), apple lines (apple muscle), lip lines, neck lines, etc. (3) Facial depressions: scarring, depressions caused by facial surgery, etc. The implanted collagen directly fills the defects in the dermis to achieve immediate filling of wrinkles and can be applied to the contour of the face. Due to the biodegradable nature of the collagen implant, it is safe to implant in the body without side effects, and the implanted collagen stimulates the body to regenerate its own collagen. Therefore, collagen supplementation at regular intervals can slow down the aging process and keep the skin young and round. Doublemax 1 collagen lasts about a year to a year and a half in the human body, and if combined with Botox it can extend the maintenance time to about a year and a half to two years.
