Beta Hydroxy Acid (BHA)

Exfoliation can be a great way to clear pores for most skin types. Generally, you can use a chemical or physical exfoliant, but chemical exfoliants have a broader range of extra benefits. AHA’s and BHA’s, or alpha hydroxy and beta hydroxy acids, are the two most well-known chemical exfoliants, but they’re slightly different!

BHAs, or beta hydroxy acids, are oil-soluble exfoliants that penetrate deep into the pores, unclog them, and prevent the formation of acne. Beta hydroxy acid improves skin texture, unclogs pores, controls oil, and can even help fade dark spots.

What are BHA’s?

Unlike AHAs, which are water-soluble and primarily target the skin's surface layers, BHAs are oil-soluble and penetrate deeper into the pores, making them particularly effective at treating acne-prone and oily skin. The most common BHA used in skincare products is salicylic acid.

Salicylic acid gently exfoliates the skin, unclogs pores, and dissolves sebum, reducing inflammation and redness associated with acne. BHAs also have anti-inflammatory and antimicrobial properties that help to prevent future breakouts.

When using BHA's on the skin, it is essential to start with a low concentration and gradually build up over time to avoid any irritation. Additionally, it is recommended to use sunscreen during the day since BHA's can make the skin more sensitive to the sun.

BHAs are typically found in cleansers, toners, serums, moisturizers, and spot treatments. Incorporating a BHA product into a skincare routine can help improve the skin's overall texture and clarity, leaving it smoother, softer, and brighter.

What are the benefits of using BHA's include:

• Exfoliation

• Oil control

• Anti-aging

• Redness and inflammation

• Resurfacing

BHA's can enhance the skin's natural ability to rejuvenate and repair itself by stimulating collagen production, which can help to reduce the appearance of scarring and uneven skin tone.

Salicylic acid helps remove dead skin cells from the skin's surface, revealing a brighter, smoother complexion. BHAs are effective at dissolving excess oil, reducing the appearance of shine, and preventing breakouts.

Generally, AHAs are better for anti-aging than BHAs, but they also help reduce fine lines and wrinkles by improving the overall texture and tone of the skin.

BHAs have anti-inflammatory properties that can help to calm redness and irritation associated with acne, rosacea, or eczema.

How can I add a beta hydroxy acid to my skincare routine?

Exfoliation is typically a part of most skin care routines. While this step can completely uplevel your skin, it’s always best to get a professional opinion if you want to add a chemical exfoliant. 

I always recommend starting slowly with a low concentration of BHAs and gradually building up. Use after cleansing and before moisturizing, and avoid the eye area and mouth. Wear sunscreen and be consistent with use to see results.

Here are some tips on how to add BHAs to your skincare routine:

• Start with a low concentration of BHAs and gradually build up. Although BHAs are safe, they can cause dryness and irritation if overused or used too often.

• Avoid using BHAs with other actives because it can cause skin sensitivity. 

• Avoid the eye area and mouth. Since BHAs are oil-soluble, they can easily penetrate the delicate skin around the eyes and be irritating. 

• It is essential to use sunscreen daily, even indoors, and reapply every two hours or as needed.
