Tretinoin is a fist ingredient, it is the most powerful member of the entire retinol family. A acid and retinol are a class of compounds that can be converted into each other in the body. From a traditional perspective, vitamin A has always been considered a vitamin, but in fact its role is similar to a hormone. But don’t panic, because A acid does not have the side effects of steroids and other hormones. It was first used as a treatment for acne in the United States at the end of the last world, but later it was found that the acne was improved while the skin lines became smoother, the contours improved, and it had a good anti-aging effect. After years of research, it finally became the first topical drug approved by the US FDA to treat UV-induced photoaging.
Vitamin A enters the skin and is converted into tretinoin by specific enzymes. By binding to the six A acid receptors on the cell, it produces countless physiological effects. It is estimated that there are dozens of them. Among them, it can be significantly improved after years of clinical observation. There are several types of skin problems:
1. Anti-inflammatory response, regulating the growth and differentiation of epidermal cells.
2. Stimulate the body’s skin to produce a large amount of collagen, strengthen the skin’s elastic fiber network, reverse the photoaging phenomenon caused by ultraviolet rays, promote the thickening of the dermis, and enhance the activity of dermal cells.
3. Improve the function of sebaceous glands, inhibit excessive secretion of oil, and improve acne and scars.
4. Inhibit the formation of melanin, dilute spots and pigmentation.
Tretinoin is used in many mid-to-high-end brand anti-aging products. Simply put, it is converted into tretinoin to exert its due effect. Until now, I can’t find a better and more effective anti-aging ingredient. Although many ingredients will be compared with it, they have never been surpassed.
