On the safety of using glycolic acid to rejuvenate the skin during lactation
In this world, women are more concerned about the maintenance of facial skin after giving birth to their children. The method of glycolic acid rejuvenation is quite effective in improving the skin, but its safety has attracted much attention during lactation.

The glycolic acid is a type of fruit acid, which is often used in beauty and skin care. It can promote the shedding of the stratum corneum, accelerate the renewal speed of keratinocytes and a small number of upper epidermal cells, and restore the ability to promote the proliferation of elastic fibers in the dermis. However, the body state of lactation women is special, and the use of medication or such skin care methods should be cautious.

From the perspective of percutaneous absorption, although glycolic acid mainly acts on the surface of the skin when rejuvenating the skin, the skin has an absorption function, and a small amount of glycolic acid may be absorbed into the systemic circulation through the skin. After entering the body, whether it will be secreted through milk, and then affect the milk is the key. At present, the number of relevant studies is still limited, and the conclusions are not consistent. Some studies show that the percutaneous absorption of glycolic acid is small, and no relevant components have been detected in the milk, which seems to have no significant effect on the milk. However, there are also views that the physiological functions of breastfeeding women are different from ordinary people, and the skin permeability may be changed. Even if it is absorbed in a small amount, it is transmitted through milk, and accumulated for a long time, it may have unknown effects on the tender body of the milk.

From the perspective of the lactating child itself, its liver, kidneys and other metabolic organs are not fully developed, and its ability to detoxify and excrete is weak. If glycolic acid enters the lactating child's body through milk, it may increase its metabolic burden and cause adverse reactions. Such as affecting the delicate skin of the lactating child, or interfering with its normal growth and development process.

To sum up, although there is no conclusive evidence that it will be harmful to the lactating child, in order to ensure the health of the lactating child, until there is more research support, lactating women should make a prudent choice. If it is not necessary, it is advisable to temporarily avoid the method of glycolic acid rejuvenation to protect the lactating child.
