AHA vs. BHA: Decoding the best acid for your face

Beauty does not come cheap – we all know that – but you could be washing away hundreds of dollars on a face wash, and even more on serums and moisturisers, without giving your skin the ideal condition to thrive in.

To truly reap the benefits of your skincare routine, adding products with AHAs and BHAs to your regime could do wonders to the skin and give it to a more youthful, supple glow. Haven’t heard of these magical ingredients?

Here’s what you need to know.

What are AHAs and BHAs
AHAs (Alpha Hydroxy Acid) and BHAs (Beta Hydroxy Acid) are hydroxy acids, also referred to as chemical peels. They are used to exfoliate dead skin cells, clear the pores of bacteria, reduce inflammation, acne scars, fine lines and ageing spots caused by sun damage. Basically, improving the overall texture and complexion in the long run. They typically come in the form of liquid masks, but can also be found in a variety of skincare products such as moisturisers, scrubs, serums and toners.

Although both groups of acids yield similar benefits, they each have distinct differences in terms of purpose and results. If you’re looking to reap more anti-ageing and hydrating benefits from your products, try AHAs, while BHAs will help you tackle acne issues.

Are there any side effects
Mild redness and tingles are common side effects of both AHA and BHA products. They have highly potent and active ingredients and skin reaction to them is common.

Those new to using these hydroxy acid peels can start with a lower level of eight to 10% for AHA and 1% BHA, before gradually moving on to higher concentration levels. Day creams and serums with AHAs should also be followed with a layer of protective sun screen because photosensitivity can leave the skin vulnerable and irritate the skin.

How to use AHA
AHAs are primarily glycolic, lactic and citric acids, though it could also include tartaric, malic and mandelic acids. They are all water-soluble exfoliating ingredients from sugary fruits that help reduce ageing spots, melasma, acne scars and reduce fine lines on the epidermis. AHA chemical peels can go up to 30% in concentration level, but those still new to AHAs or have dry and sensitive skin can start with formulations of 10% or lower. This will give your skin a gentler introduction to AHAs before gradually working your way up to higher concentration levels over time.

What is BHA
BHAs are oil-soluble organic compound exfoliators, typically salicylic acid, that are best used to relieve clogged pores, blemishes and acne scars, as well as remove black heads and white heads. Unlike AHAs, they are able to penetrate underneath the skin as well as on the surface, effectively breaking down and clearing dead skin cells and bacteria from within the pores and preventing breakouts. The highest level of BHA concentration is a mere 2%, though 1% BHA will still offer an effective cleanse on sensitive skin whilst providing a calmer formula to ease redness and inflammation.

Can you combine AHA and BHA?
Using AHAs and BHAs can yield visible benefits for the epidermis, both inside and out. When used in combination, it can clear the surface of the skin and underneath it, supporting hydration and allowing for the rest of your skincare products to work more effectively.

As for sensitive skin, these potent acids can leave the surface of the skin temporarily dryer,  and more vulnerable and sensitive due to its active exfoliating ingredients. In that case, you can split the two group of acids into day and night routines, rather than layering the two products on top of one another.
