What is the use of adding vitamin A to skincare products?

We know that the vast majority of active ingredients have their own fields. Hyaluronic acid moisturizing, arbutin whitening, Boseline anti wrinkle, salicylic acid acne, and occasionally a few young people with slash, such as vitamin C, resveratrol, both whitening and anti-aging, but more than three effects are basically gone.
There are millions of skincare ingredients, but there are not many that can be used. However, one ingredient is an exception, which is the “universal oil” in skincare ingredients – vitamin A.
Why is vitamin A called the “universal oil” in skincare ingredients? What are the effects of adding vitamin A to skincare products? I’ll tell you the answer today~
Vitamin A is a fat soluble vitamin. Vitamin A can maintain the normal growth, differentiation, proliferation, and keratinization of skin cells. It is rich in various vegetables and fruits, and is also abundant in the liver of animals, meeting the needs of meat and vegetable pairing.
Vitamin A has many forms and is not a single compound, but a series of derivatives of retinol, including retinol, retinol aldehyde, retinoic acid, retinol acetate, and retinol palmitate.
The powerful skincare benefits of vitamin A make it often used in various skincare products
However, retinol cannot directly act on the human skin. It needs to be converted into retinoic acid by human enzymes in order to have a skincare effect.
The use of vitamin A in skincare products only involves the use of retinol, retinol, and their derivatives. Retinol and retinol can be metabolized quickly to retinoic acid, with the fastest efficacy.
Vitamin A plays a crucial role in regulating the differentiation of keratinocytes, so its efficacy is like the gate of a dam.
✔ Whitening:
The deposition of melanin is the culprit of darkening. Vitamin A can inhibit pigment deposition and promote the shedding of the stratum corneum, effectively solving the problem of pigment accumulation and having strong whitening effects.
✔ Removing wrinkles:
Vitamin A, as a mediator, can regulate the metabolism of the epidermis and stratum corneum, while promoting collagen cell synthesis. For existing wrinkles and muscle relaxes, supplementing with collagen can help your skin become tender and smooth again.
✔ Improving photo aging:
When the human skin is exposed to ultraviolet radiation, it can stimulate the metalloproteinases (MMPs) in the body, disrupt the normal collagen metabolism order, and be excessively stimulated by ultraviolet radiation, which can produce a stress response, allowing new and old collagen to be eliminated from the body without distinction.
So vitamin A has a unique effect, effectively suppressing the active rebels of metalloproteinases MMP1 and MMP9, which are less susceptible to UV stimulation, effectively preventing the loss of collagen, preventing photoaging, reducing wrinkles, and tightening the skin.
✔ Acne removal:
Vitamin A is so magical that it can not only promote the cell regeneration of the basal stratum corneum, but also accelerate the metabolic rate of the stratum corneum. Similar to the effect of fruit acid, it promotes the shedding of excess keratin and unblocks pores. Therefore, it is often used to treat acne and can also achieve anti-inflammatory effects.
