Is there a difference between A-alcohol and retinol? Precautions for using A-alcohol

A alcohol is retinol. Rea alcohol is a highly effective and relatively mild skin care ingredient that can whiten, remove spots and tighten the skin. However, due to its quick effect, we still need to pay attention to some matters when using rea alcohol. Let's take a look.

Is there a difference between A-Retinol and Retinol?

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 retinol, 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 tretinoin, which is also a popular skin care product, but it requires a prescription.

Precautions for using A-alcohol

1. Build tolerance

Gradual method - test locally first, then gradually expand to the entire face; start with half the amount after moisturizer, and use it at night every other day or every two days. After two weeks without any abnormalities, you can slowly increase the dosage and use it every other day or every day. Although Retinol is a strong medicine, it still needs to be used for more than two or three months, so don't rush.

2. Use with other ingredients

(1) Niacinamide: Retinol makes the epidermis thinner, and niacinamide is a good synergistic partner. It can appropriately enhance the synthesis of ceramides and slightly accelerate the repair of the epidermal barrier. However, both may cause intolerance, so caution is needed. It is generally recommended to start with low concentrations of both, or only one high concentration.

(2) Adenosine: Adenosine also has the effect of improving epidermal differentiation, and can enhance the effects of each other when used in combination with retinol. A big problem with A acid/retinol is the side effect of peeling. Genistein can slow down peeling and is also a good whitening ingredient, so it is a very good partner for A acid.

(3) Moisturizing ingredients: ceramide, repairing plant oil, squalane, etc., which can repair and moisturize while also playing a sufficient sealing role. Calming ingredients such as allantoin, glucan, B5, licorice extract, etc. can relieve inflammation, reduce redness, and help the skin temporarily survive the abnormal differentiation period.
