AHA and BHA are both acids known for their effective exfoliating properties and their ability to address various skin concerns.

AHA, being water-soluble, is ideal for dry skin, as it helps hydrate the skin while removing dead skin cells from the surface. On the other hand, BHA is oil-soluble, making it more suitable for oily skin. It can penetrate deep into the pores, helping to clear blockages that cause acne. Given their distinct advantages, can these two acids be used together?

How AHA and BHA Work

Alpha Hydroxy Acid (AHA) is water-soluble and primarily works on the skin's surface. AHA helps exfoliate by removing dead skin cells, increasing hydration, and stimulating collagen production, which leads to smoother and healthier skin.

Beta Hydroxy Acid (BHA), in contrast, is oil-soluble, allowing it to penetrate pores and clear away excess oil and dirt that can cause blockages. BHA is particularly effective for oily or acne-prone skin due to its anti-inflammatory and antibacterial properties, which help reduce inflammation and prevent acne outbreaks.

Know the Risks of Combining AHA and BHA

Combining AHA and BHA is believed to offer dual benefits: AHA hydrates and brightens the skin’s surface, while BHA works deeper in the pores to address oil build-up. This combination can be especially helpful for individuals with combination skin who deal with clogged pores and dull skin.

However, it’s essential to be aware of potential side effects when using both acids together, such as:

• Irritation and redness, especially for those new to using these acids.

• Dry and flaky skin.

• Increased sensitivity to sunlight, which may heighten the risk of sun damage.

Tips for Combining AHA and BHA

While there are some risks, combining AHA and BHA is entirely possible if done carefully. To minimize irritation and achieve the best results, consider the following tips:

Use them at different times

If you're new to AHA or BHA or have sensitive skin, it's advisable to use these products at different times of the day. For example, apply AHA in the morning and BHA in the evening.

Use alternately

To reduce irritation, you can alternate between AHA and BHA on different days. There's no need to use them every day—2 to 3 times a week is sufficient.

Start with a low concentration

If you're a beginner, opt for products with a low concentration of AHA and BHA. As your skin adapts, you can gradually increase the strength of the products.

Avoid combining them with other strong active ingredients

Using AHA and BHA with other potent ingredients like retinol or vitamin C can heighten the risk of irritation. If you wish to incorporate other active ingredients into your routine, consider using them on separate days or allowing time between applications.

Always use a moisturizer and sunscreen

Since AHA and BHA can make your skin more sensitive to sunlight, it's crucial to apply a moisturizer and sunscreen with an SPF of at least 30 every day.

Do a patch test

Before applying AHA or BHA to your entire face, perform a patch test on a small area of your skin to check for any allergic reactions or irritation.

Before starting an AHA and BHA routine, it's best to consult a dermatologist, especially if you have sensitive skin. You can also seek advice through the consultation feature on the Ai Care app, available for download on the App Store or Play Store.
