When it comes to the compatibility of glycolic acid and retinol
, both glycolic acid and retinol are commonly used in skin care. However, whether the two can be used together is the concern of many caregivers.

Glycolic acid is a fruit acid or the like, which has the effect of rejuvenating the skin. It can loosen the connection between keratinocytes, make old keratin fall off, make the skin surface smooth, more uniform, and can promote skin metabolism and help collagen production, which is very beneficial for improving skin quality.

Retinol, also known as vitamin A alcohol, can regulate the metabolism of the epidermis and stratum corneum, help anti-wrinkle, light spots, improve skin firmness, enhance skin elasticity, and has a long-standing reputation in the field of skin anti-aging.

As for the compatibility of the two. Although both glycolic acid and retinol are beneficial to the skin, using them together may pose a risk. Glycolic acid can cause the stratum corneum of the skin to thin and improve skin permeability. If retinol is used together at this time, the irritation of retinol to the skin may be exacerbated. Retinol is already irritating, and when some people use it alone, the skin may already be red, desquamation, tingling and other discomforts. If the two are used together, this discomfort may be more significant, or even cause adverse conditions such as skin allergies.

However, if the skin tolerates it well and uses it properly, it may also be able to reap the benefits of both. If you start with low-concentration products, gradually increase the dosage and frequency. Initially, you can use it at intervals, and then adjust the use plan moderately after the skin adapts. And during use, you need to pay close attention to the skin's reaction. If there is any discomfort, you should stop using it immediately.

In short, the compatibility of glycolic acid and retinol needs to be done carefully according to personal skin conditions. To maintain the skin, safety should be the priority, and the ideal effect can be achieved step by step.
