On the combination of glycolic acid and retinol
The method of skin maintenance, the method of combining glycolic acid and retinol, is worth exploring. Glycolic acid has the power of gentle exfoliation, can exfoliate waste exfoliation, refresh the skin, uniform color, and promote subsequent nutrient absorption. Retinol, a vitamin A alcohol, can stimulate collagen production, smooth fine lines, and improve skin quality.

However, when the two are used together, caution is required. Ethanol is acidic and lively, with a certain degree of irritation, and retinol is also at risk of irritation to the skin. If used rashly, it may cause skin discomfort, such as redness, tingling, desquamation, etc. Therefore, when using it for the first time, it is advisable to try it in a small amount and at a low concentration. You can first use glycolic acid products to cleanse your face at night, apply it thinly to your face, and then introduce retinol after your skin adapts for a few days. And when you first use retinol, you should also start with low frequency and low dose, such as once a week, and gradually increase to the tolerance level.

The order of combination is also exquisite. You can apply glycolic acid first, and then thinly apply retinol after it absorbs for a while. In this way, you can use the power of glycolic acid to promote penetration, so that retinol can better play its effect and reduce its irritation. During this period, you must pay attention to skin moisturization and sun protection. Moisturizers can stabilize the skin barrier and reduce irritation and discomfort; sunscreens can prevent ultraviolet damage to the skin due to the combination of the two or increase skin photosensitivity, so as not to waste all previous efforts.

In short, the combination of glycolic acid and retinol, if you can follow the correct method, step by step, pay attention to skin response and maintenance, you will be able to achieve the ideal skin care effect, making the skin radiant, tender and firm.
