On the use of retinol and glycolic acid every other day
Today's skin care methods, retinol and glycolic acid are quite commonly used. However, whether the two can be used every other day, there are different opinions, and it needs to be explored in detail.

Retinol is a derivative of vitamin A. It has significant effect on the skin, can promote cell renewal, tighten the skin, fade wrinkles, and improve uneven skin tone. However, it is strong, and the skin may be intolerant when used for the first time, such as redness, peeling, tingling, etc.

Glycolic acid is a type of fruit acid with tiny molecules. It can penetrate deep into the stratum corneum of the skin, loosen the connections between keratinocytes, shed old keratin, make the skin smooth and delicate, and can also brighten the complexion and improve the disease of enlarged pores. However, it is irritating to a certain extent, especially those with high concentrations.

If you use the two every other day, you need to clarify the characteristics of the skin. Those with strong skin tolerance may have a try. Start with a low concentration of retinol, such as 0.1% - 0.3%. After cleansing at night, wait for the skin to be dry, apply thinly to the face, and after a few weeks of adaptation, you can increase it according to the situation. The same is true for glycolic acid. Start with low-concentration products, such as 5% - 10%. On another day, apply thinly after cleansing.

For those with sensitive skin, this rule should be followed with caution. Before use, it is recommended to try it in a small area behind the ear or on the inside of the forearm, and observe it for 24-48 hours. If there is no discomfort, it can be gradually used on the face. And during use, pay close attention to the skin's reaction. If you feel unwell, you should stop using it immediately.

Furthermore, after using retinol and glycolic acid, the skin's resistance to ultraviolet rays decreases. Therefore, be sure to do a good job of sun protection during the day, apply sunscreen, wear a hat, use an umbrella, etc., to prevent sunburn and sun aging.

In short, retinol and glycolic acid are used every other day to tolerate skin or to reap good results, but sensitive skin should be cautious. Proper use can help skin glow; careless use can cause skin damage. Skin care, when your mileage may vary, step by step, is the right way.
