In recent years, the use of glycolic and lactic acid in skincare products has gained significant popularity. These alpha hydroxy acids (AHAs) are touted for their exfoliating and rejuvenating properties. However, it is crucial to approach the use of these acids with caution. While they may offer some benefits, there are potential risks and side effects associated with their usage. In this article, we will explore the reasons why glycolic and lactic acid should not be used indiscriminately in skincare routines.
Glycolic and lactic acid are potent exfoliants that work by dissolving the outer layer of dead skin cells, revealing a fresher complexion. However, this exfoliating action can be too harsh for some individuals, leading to skin irritation, redness, and sensitivity. Those with sensitive or compromised skin barriers should exercise caution when using products containing these acids.
AHAs, including glycolic and lactic acid, make the skin more susceptible to sun damage. By exfoliating the outer layer of the skin, these acids can temporarily thin the skin’s protective barrier. This thinning effect reduces the skin’s natural defenses against harmful UV rays, making it more prone to sunburn, hyperpigmentation, and long-term damage. It is crucial to use broad-spectrum sunscreen and limit sun exposure when incorporating these acids into your skincare routine.
Regular exfoliation is beneficial for maintaining a healthy complexion. However, excessive or frequent use of glycolic and lactic acid can lead to over-exfoliation. Over time, this can disrupt the skin’s natural moisture balance, compromise its protective barrier, and cause dryness, flakiness, and increased sensitivity. It is important to follow the instructions on product labels and not exceed recommended usage frequencies to prevent these negative effects. While relatively rare, allergic reactions to glycolic and lactic acid can occur. Some individuals may experience contact dermatitis, characterized by redness, itching, and inflammation upon application of products containing these acids. Patch testing new skincare products that contain AHAs can help identify potential allergic reactions before incorporating them into your routine.
Pregnant and nursing individuals should be cautious when using glycolic and lactic acid in skincare products. Although these acids are generally considered safe in low concentrations, it is advisable to consult with a healthcare professional before incorporating them into your routine. Some studies suggest a potential risk of increased skin absorption and the potential transfer of these acids to the fetus or nursing infant.
While glycolic and lactic acid can offer benefits when used properly, it is essential to approach them with caution. The potential risks, including skin sensitivity, sun damage, over-exfoliation, allergic reactions, and precautions during pregnancy and nursing, must be considered. To ensure the safety and effectiveness of your skincare routine, it is always advisable to consult with a dermatologist or skincare professional before incorporating new products containing these acids.
