Precautions for the use of glycolic acid

Glycolic acid is widely used in the field of skin care. However, when using it, when it is clear that it is appropriate to avoid it, it can achieve good results and keep the skin healthy.

Glycolic Acid Dos

For example, glycolic acid skin care products with a concentration of 2% - 5% can gradually adapt the skin to avoid discomfort caused by strong irritation, such as redness and tingling. It is wise to gradually increase the concentration and allow the skin to adapt to the process.
2. ** Best choice for evening use **: Night is the golden time for skin self-repair. Glycolic acid can be used at this time to better exert its effect. And the light at night is weak, which can reduce the risk of increased skin sensitivity to light caused by glycolic acid and reduce the possibility of sunburn.
3. ** Do a good job of moisturizing and cooperating **: Glycolic acid has exfoliating effect or causes skin moisture loss. At the same time, it needs to be used with moisturizing products, such as essence rich in hyaluronic acid, moisturizing cream, etc., to maintain skin hydration and make skin healthy and stable.

Glycolic Acid Don'ts
1. ** Avoid overuse **: Even though glycolic acid has many benefits, it should not be overly dependent. Frequent use may make the stratum corneum of the skin too thin, causing damage to the skin barrier, becoming sensitive and fragile, and increasing the chance of external irritation. It is recommended to formulate a reasonable frequency of use according to the skin's tolerance, such as 1-2 times a week for dry and sensitive skin, and 2-3 times a week for oily skin.
2. ** Do not mix with irritating ingredients **: Glycolic acid has been irritated to the skin. Do not mix with other strong irritating ingredients, such as high-concentration salicylic acid, retinoic acid, etc. Otherwise, the irritation will be superimposed, the skin will be overwhelmed, or there will be serious discomfort, such as redness, swelling,
3. ** Avoid the skin around the eyes **: The skin around the eyes is delicate and weak, and the irritation of glycolic acid is too large for it. When using the product, be careful to avoid the eye area to prevent eye discomfort such as tingling, tears, and even affect eye health.
