Alpha Hydroxy Acids (AHAs) and Beta Hydroxy Acids (BHAs) are two types of exfoliants widely used in skincare to promote healthy, radiant skin. AHAs, such as glycolic acid and lactic acid, are water-soluble acids derived primarily from fruits and milk. They work by dissolving the bonds holding dead skin cells to the surface, facilitating their removal and revealing fresher, smoother skin underneath. This makes AHAs particularly effective for addressing issues like fine lines, uneven skin tone, and surface-level hyperpigmentation.

On the other hand, BHAs, with salicylic acid being the most common, are oil-soluble acids that penetrate deeper into the pores. This makes them especially beneficial for individuals with oily or acne-prone skin, as they can effectively unclog pores and reduce sebum production, thereby helping to prevent and treat breakouts. BHAs also possess anti-inflammatory properties, making them suitable for calming irritated skin.

What are the benefits of combining AHAs and BHAs together?

Combining Alpha Hydroxy Acids (AHAs) and Beta Hydroxy Acids (BHAs) in skincare products can offer a comprehensive range of benefits, enhancing the overall effectiveness of your skincare routine. Here are some key benefits of using products that incorporate both AHAs and BHAs.

#1 Comprehensive Exfoliation

AHAs work on the skin's surface to dissolve dead skin cells and promote cell turnover, improving texture and radiance. At the same time, BHAs penetrate deeper into the pores to remove debris and excess oil, helping to prevent and treat acne.

#2 Improved Skin Texture and Tone

The combination helps to smooth out uneven skin texture by addressing surface irregularities with AHAs and clearing out pores with BHAs. It has been noted that regular use can lead to a more even skin tone, reducing the appearance of hyperpigmentation, sun damage, and age spots.

#3 Enhanced Acne Treatment

BHAs, especially salicylic acid, are effective in unclogging pores and reducing acne. When combined with AHAs, the overall exfoliation process is more thorough, preventing the formation of new breakouts and helping to fade post-acne marks.

#4 Increased Collagen Production

AHAs, particularly glycolic acid, can stimulate collagen production, which helps to improve skin elasticity and reduce the appearance of fine lines and wrinkles. On the other hand, the deep cleaning action of BHAs ensures that the skin remains clear, allowing for better absorption of other anti-aging ingredients.

#5 Hydration and Moisture Retention

AHAs have humectant properties, meaning they can attract and retain moisture in the skin, improving overall hydration. By keeping the pores clean, BHAs allow for better penetration and efficacy of hydrating products applied afterward.

#6 Reduced Inflammation and Redness

BHAs possess anti-inflammatory properties, which can help to calm irritated skin and reduce redness associated with acne and rosacea. Combining them with AHAs can enhance the soothing effects while maintaining effective exfoliation.

#7 Enhanced Product Penetration

By removing dead skin cells on the surface with AHAs and clearing out pores with BHAs, the skin is better prepared to absorb other active ingredients from serums, moisturizers, and treatments applied subsequently.

#8 Balanced Oil Production

BHAs help regulate sebum production, which is beneficial for oily and acne-prone skin types. When used alongside AHAs, this can create a balanced environment, reducing excess oil while maintaining adequate moisture levels.

Tips for Use

When incorporating products that combine AHAs and BHAs into your skincare routine, it’s important to start with lower concentrations to allow your skin to build tolerance. It is also recommended to use them primarily at night, as both AHAs and BHAs can increase sun sensitivity.

Never neglect sun protection – religiously follow up with a broad-spectrum sunscreen during the day to protect your skin from UV damage.
