As an effective retinol, retinol is often used together with skin care products containing niacinamide.

How often should I use A-alcohol skin care products?

A alcohol is generally used 2 to 3 times a week, and the frequency should not be too high. It cannot be used every day.

Everyone's skin's tolerance to A alcohol is different. When used in the initial stage, the amount should not be too large and the concentration should not be too high, otherwise the skin will easily experience peeling, dryness, redness, swelling, acne, etc. If any skin problems occur after using retinol, you should stop using it, or use it with mild or hydrating skin care products to reduce the irritation of retinol to the skin.

People who are preparing to become pregnant or are already pregnant should not use retinol. It is also not recommended for people with poor skin as it is too irritating.

The dangers of long-term use of A-alcohol

If high concentrations of retinol are used for a long time, it will easily lead to accelerated keratin shedding. If the skin's barrier function is incomplete, it will further damage the skin barrier, making the skin fragile and prone to redness, dryness, and peeling. Long-term use of low concentrations of retinol will not cause any harm if the skin tolerates it.

Precautions when using retinol

1. Alanine is irritating to the skin, so a tolerance process should be established when using alanine.

2. It is not recommended to use high-concentration retinol for a long time, and it is generally believed that products with a concentration exceeding 0.5% are high-concentration products.

3. A alcohol will promote the renewal of keratinocytes and accelerate the shedding of keratin, so it is not suitable for dry and sensitive skin.

4. Rea alcohol can cause the stratum corneum to fall off, making the skin more vulnerable to damage from ultraviolet rays. Moreover, rea alcohol itself is photosensitive and will decompose into more irritating free radicals when exposed to light. Therefore, it is not recommended to use rea alcohol during the day.

5. Pregnant women cannot use retinol.

Can A alcohol and facial cream be used together?

A alcohol can be used together with facial cream.

Retinol is quite irritating, and those who have used it know it. In order to reduce this irritation, you can mix retinol into the facial cream. I still feel that retinol is very irritating even when mixed into face cream, so next time I will have to choose retinol with a lower concentration.
