AHA and BHA for Skin: What to Know

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Alpha Hydroxy Acids (AHAs) and Beta Hydroxy Acids (BHAs) are popular ingredients in skincare products, known for their exfoliating properties and ability to improve skin texture and appearance. This article explores the benefits, mechanisms, and considerations for using AHAs and BHAs in skincare routines.

What are AHAs and BHAs?

Alpha Hydroxy Acids (AHAs)

AHAs are water-soluble acids derived from fruits and milk. Common types include glycolic acid, lactic acid, tartaric acid, and gluconolactone. They work by exfoliating the surface of the skin, promoting cell turnover, and improving skin texture and tone.

Beta Hydroxy Acids (BHAs)

BHAs, primarily salicylic acid, are oil-soluble and can penetrate deeper into the pores. They are particularly effective for treating acne and oily skin by exfoliating inside the pores and reducing inflammation.

Benefits of AHAs

Exfoliation and Skin Renewal

AHAs enhance the desquamation of the stratum corneum, leading to smoother and more radiant skin. They promote the shedding of dead skin cells, which can help reduce the appearance of fine lines and wrinkles1.

Improved Skin Barrier Function

Certain AHAs, such as gluconolactone and tartaric acid, have been shown to improve skin barrier function and reduce skin irritation. These AHAs can modulate the stratum corneum barrier, making the skin more resilient to irritants1.

Benefits of BHAs

Acne Treatment

BHAs are effective in treating acne due to their ability to penetrate and exfoliate inside the pores. Salicylic acid, the most common BHA, helps to unclog pores, reduce sebum production, and decrease inflammation, making it ideal for acne-prone skin.

Anti-Inflammatory Properties

BHAs possess anti-inflammatory properties, which can help soothe irritated skin and reduce redness. This makes them suitable for individuals with sensitive or acne-prone skin.

Combining AHAs and BHAs

Synergistic Effects

Combining AHAs and BHAs can provide a comprehensive exfoliation, targeting both the surface and deeper layers of the skin. This combination can enhance overall skin texture, clarity, and radiance.

Considerations for Use

When using AHAs and BHAs together, it is essential to introduce them gradually into your skincare routine to avoid irritation. Start with lower concentrations and increase as your skin builds tolerance. Always use sunscreen during the day, as these acids can increase skin sensitivity to UV rays.

Conclusion

AHAs and BHAs offer significant benefits for skin exfoliation, renewal, and treatment of various skin concerns. AHAs are particularly effective for improving skin texture and barrier function, while BHAs excel in treating acne and reducing inflammation. Combining these acids can provide a synergistic effect, enhancing overall skin health and appearance. However, it is crucial to use them correctly to avoid potential irritation and maximize their benefits.
