On the use of retinol and glycolic acid in the same way as a safe
method for skin care, retinol and glycolic acid are both commonly used. However, whether the two can be used together, there are different opinions, it is really related to the safety of the user's skin, and it must be observed.

Retinol is good for the skin, can promote cell renewal, increase collagen production, remove wrinkles and freckles, make the skin smooth and delicate, and rejuvenate. Glycolic acid has the ability to exfoliate, smooth pores, improve uneven skin tone, treat acne, and make the skin refreshing and shiny.

However, the two are used together, and the advantages and disadvantages coexist. From its advantages, the synergistic power can make the skin improve more effectively. Retinol promotes cell renewal, glycolic acid helps exfoliation, two-pronged approach, the skin's metabolism accelerates, and the effect is more obvious on wrinkles, pigmentation, roughness and other diseases.

However, its disadvantages cannot be ignored. Retinol and glycolic acid are both irritating. If the skin is sensitive, use one alone, or there may be discomfort. When the two are used together, the irritation is superimposed, and the skin is prone to redness, swelling, tingling, and desquamation. What's more, it may cause damage to the skin barrier, lower defense, and be easily invaded by external evil.

If you want to know whether the two are used together, you should first examine the nature of the skin. If the skin is strong and resistant to irritation, use a low-concentration product in a small area during the initial test to observe the skin's reaction. If there is no discomfort, gradually expand the area and frequency of use. If the skin is sensitive and delicate, be cautious, or consult a doctor or skin care expert first, and do as he says.

In short, retinol and glycolic acid are used together, and the effect may be increased, but the risk also exists. Users must carefully observe the skin and act prudently to ensure skin well-being, enjoy the benefits of skin care, and avoid the harm of irritation.
