Understanding Acids in Skincare: The Difference Between AHA and BHA

Updated: 1 hour ago

If you’re looking to achieve glowing skin, incorporating acids into your skincare routine could be a game-changer. However, the world of acids can be confusing, especially when deciding between AHAs (Alpha Hydroxy Acids) and BHAs (Beta Hydroxy Acids). The good news? With expert guidance from me, Dr. Felicity McGuire, in my clinic in Didsbury, Manchester, you can feel confident in choosing the right treatments and products to suit your unique skin needs.

Let’s break down the key differences between AHAs and BHAs, explore their benefits, and highlight how professional treatments can help you achieve your skincare goals.

What Are Acids in Skincare?

Acids are powerful ingredients that target multiple skin concerns, from dullness and pigmentation to acne and fine lines. AHAs and BHAs are the two main types of exfoliating acids:

AHAs: Water-soluble acids that work on the skin’s surface to improve texture, tone, and hydration.
BHAs: Oil-soluble acids that penetrate deeper into pores, making them ideal for clearing congestion and reducing breakouts.

Both types of acids have unique benefits, but choosing the right one depends on your skin type and concerns.

AHAs vs. BHAs: Key Differences

How They Work

AHAs, like glycolic and lactic acid, exfoliate the top layer of dead skin cells, revealing a brighter, smoother complexion.
BHAs, such as salicylic acid, work deep within the pores to clear oil, dirt, and bacteria, making them effective for acne-prone skin.

Photosensitivity

One significant difference is how they affect your skin’s response to sunlight:

AHAs, particularly glycolic acid, can make your skin more sensitive to UV radiation.
BHAs, on the other hand, are thought to have mild photoprotective properties.

Regardless of your choice, wearing sunscreen daily is non-negotiable to protect your skin from sun damage.

Skin Type Suitability

AHAs: Generally suitable for all skin types, but especially beneficial for dry, dull, or mature skin. Sensitive skin types may prefer lactic acid due to its gentler nature.
BHAs: Ideal for combination, oily, or acne-prone skin, but they may be too drying for those with sensitive or very dry skin.

The Benefits of Using Acids

Incorporating AHAs or BHAs into your skincare routine can deliver impressive results:

AHAs: Boost hydration, even out skin tone, and minimize the appearance of fine lines and wrinkles.
BHAs: Clear clogged pores, reduce acne, and improve overall skin texture.

The result? A smoother, healthier, and more radiant complexion.

Choosing the Right Acid for Your Skin Type

Your skin type and concerns will determine whether AHAs or BHAs are right for you:

If you struggle with dullness, dry patches, or fine lines, AHAs like glycolic or lactic acid can help.
If your main concerns are oily skin, blackheads, or breakouts, BHAs like salicylic acid are your go-to.

Common Mistakes to Avoid When Using Acids

To get the most out of your skincare acids, avoid these common mistakes:

Skipping sunscreen: Both AHAs and BHAs can increase your skin’s sensitivity to the sun, so daily SPF is essential.
Overusing acids: Too much exfoliation can damage your skin barrier. Start slow and follow professional guidance.
Mixing incompatible ingredients: Avoid combining acids with strong actives like retinol or vitamin C without professional guidance.

Conclusion

Understanding the difference between AHAs and BHAs is key to unlocking the potential of your skincare routine. Whether you need the surface exfoliation of an AHA or the pore-clearing benefits of a BHA, the right choice depends on your skin’s needs.
