Retinol:All Stars In The Anti Aging World

Anti-wrinkle has always been an eternal topic

In recent years, we have seen the "retinol" ingredient in all kinds of anti-wrinkle skin care products, but what is retinol? Retinol is A type of vitamin A, is a derivative of vitamin A, known as the anti-wrinkle world's "carry", is the gold standard ingredient in skin care, as the industry recognized as one of the effective anti-wrinkle ingredients. It can promote the skin's renewal process, helping to reduce fine lines, wrinkles and improve uneven texture.

Retinol, also known as retinol, is A form of vitamin A often used in skin care products that acts as an antioxidant, prevents free radicals from destroying collagen, and stimulates collagen regeneration.

Retinol Can be converted into retinoic acid in the body, can inhibit the activity of the metal matrix proteinase MMPs in the dermis that breaks down collagen, and can effectively block the damage of free radicals to the skin.

Retinol, also called A alcohol, belongs to the vitamin A family. In the skincare industry, ingredients such as alcohol are known as "skincare versatile hands". This is mainly because its functions are too powerful. Generally, skincare ingredients are relatively targeted, and few skincare ingredients have more than three effects. In addition, Retinol (A alcohol) needs to be converted into A acid to act, so it can be understood that the two functions can be equivalent.

Skin care principle of Retinol Retinol, also known as a derivative of vitamin A, is one of the important nutrients to promote cell renewal. It is a superstar of highly active anti-aging ingredients recognized by the dermatology industry, and a gold warrior of anti-aging. Alcohols produce numerous physiological effects by converting into A acid in the body and binding to six A acid receptors on cells, including defense against inflammation, regulating the growth and differentiation of epidermal cells, promoting collagen production, and regulating cell regeneration speed. They also have effects such as fine pores, even skin tone, smoothing fine lines, and brightening dark skin, tightening, and anti-aging.

① Anti aging: Retinol can inhibit the activity of Matrix metalloproteinase (MMP), reduce the damage to collagen and fibrous tissue, play a role in weakening fine lines and improving sagging

② Regulating metabolism: accelerating keratinocyte shedding

③ Brightening skin tone: inhibits melanin production while accelerating melanin metabolism to improve dullness

④ Regulating sebum secretion: Has a certain oil control ability, similar to brushing acid to clear pore channels and reduce the breeding of acne

⑤ Increase the skin's water retaining capacity and thicken the epidermis: when Retinol acts on the dermis, the content of Glycosaminoglycan in the skin will also increase significantly, and then the water locking capacity of the dermis will also be improved, making the skin Q elastic and tender.

1. Retinol

Retinol is a form of vitamin A, also known as vitamin A1 or Retinol ether. It is a fatty organic compound, mainly found in animal foods, such as liver, Cod liver oil, butter, butter, etc.

Retinol is an important nutrient with many physiological functions. Firstly, it is a component of retinal rhodopsin and plays an important role in human vision. Secondly, Retinol is involved in the development and maintenance of skin, teeth, bones and other tissues and organs.

2.Tretinoin

Tretinoin is one of the derivatives of Retinol, and its chemical name is all trans retinoic acid. It is an oxidation product of vitamin A and also a potent epidermal growth factor. Tretinoin is widely used in the field of medicine and beauty. The biosynthesis process of Tretinoin is very complex and requires multi-step reaction to generate. Compared with Retinol, it has simpler structure, stronger bioactivity and bioavailability. Retinoic acid can promote normal differentiation and metabolism of epidermal cells, increase the synthesis of collagen and elastic fibers, and thus reduce skin fine lines and relaxation. In addition, Tretinoin can also inhibit the production of melanin, reduce the secretion of sebum in hair follicles, and has obvious effects on acne and other skin problems.

3. Difference between Retinol and Tretinoin

Although both Retinol and Tretinoin belong to the vitamin A family, there are obvious differences in their structures, properties and functions. First, Retinol is a form of vitamin A, which is mainly used for the nutritional needs of the body; Tretinoin is a skin growth factor, mainly used to treat skin problems.

Secondly, Retinol has a wide range of physiological functions. It not only participates in a variety of physiological activities such as vision, immune system and reproductive system, but also can promote the normal development and maintenance of bones, teeth, skin and other tissues and organs. The physiological role of Tretinoin is relatively limited, mainly to promote normal differentiation and metabolism of epidermal cells, thus improving skin problems.
