Is long-term use of retinol really good for the skin? What should not be used with retinol?

A alcohol contains fruit acid, which can make the skin surface smoother. However, since fruit acid contains certain irritation, many female friends will experience skin intolerance after using it. So can A alcohol be used for a long time?

Long-term use of low-concentration retinol, which is tolerated by the skin, will not cause any harm. Long-term use of high-concentration retinol can easily lead to accelerated keratin shedding. If the skin barrier function is incomplete, it will further damage the skin barrier, making the skin fragile and prone to redness, dryness, and peeling.

1. Long-term use of low concentrations of retinol

It effectively promotes the renewal of keratinocytes and the production of collagen, achieving the effects of removing wrinkles, fading spots, and rejuvenating the skin, effectively preventing skin aging.

2. Long-term use of high concentrations of retinol

The rapid renewal of keratinocytes leads to incomplete skin barrier function, the skin becomes thinner and thinner, moisture is easily lost, the ability to resist ultraviolet rays becomes weaker, the skin becomes more and more sensitive, and redness, dryness, peeling, etc. are prone to occur.

Retinol cannot be used together with various acid products. The reason is very simple. Everyone wants whitening and anti-aging, but these two cannot be easily achieved at the same time. Retinol cannot be well converted when it comes into contact with acids, and the anti-wrinkle effect will be discounted. Try not to use retinol and acids together. Retinol and acids such as fruit acid and salicylic acid are all highly irritating ingredients. Most people still recommend not to use them together. Usually, you may not feel any problem after using it once or twice, but it is hard to say after a long time.

Vitamin C and retinol are both excellent skin care ingredients, but they work best at different pH values. The best pH value for vitamin C is ≤3.5, while the best pH value for retinol is between 5.5-6.5. For safety and effectiveness considerations, it is best not to use these two ingredients at the same time.

After being absorbed by the skin, retinol is converted into retinoic acid in the skin, which can accelerate skin metabolism, produce collagen, reduce sebum, and lighten epidermal pigmentation. Its main effect on the skin is to reduce wrinkles on the surface of the skin, increase skin thickness, and fight against photoaging. Retinol and niacinamide are a good combination.

Retinol is absorbed through the skin and enters the skin tissue cells, and is finally converted into A acid to work: accelerate the shedding of keratin, increase skin metabolism, and speed up the renewal of epidermal cells, thereby revealing smoother skin.

Retinol is particularly effective in promoting collagen production. It can act on the dermis to accelerate collagen production and prevent wrinkles. Acne-prone skin is most suitable for using retinol ingredients to treat some skin inflammatory diseases, such as acne, keratosis pilaris and psoriasis.

A alcohol and retinol are the same, there is no difference, they are just different names for the same ingredient. Retinol is a type of vitamin A acid, which is a derivative of vitamin A. Vitamin A is not just a single compound, but a series of retinol derivatives including retinol, retinoic acid and retinol palmitate.

Vitamin A acids are often used as raw materials in skin care products because they are believed to help the skin stay youthful and vibrant. Retinol and other vitamin A acids are believed to help increase the production of collagen in the skin. Collagen is the component that keeps the skin plump. Increasing the collagen in the skin can help the skin eliminate subtle fine lines and wrinkles.

However, it should be noted that only derivatives of retinoic acid can be added to cosmetics. For example, the maximum content of retinol in cosmetics is 1%. Another type of vitamin A acid is retinoic acid, which is also a popular skin care product, but a prescription is required for its use.
