Creating the perfect skincare routine to defy time goes hand in hand with finding an exfoliation solution that works best for you. Alpha hydroxy acids (AHAs) are a group of acids that are practically unbeatable when it comes to exfoliation and skin rejuvenation. All these acids aren’t created equal. Some are better for specific skin types, and some have more data backing their efficiency. Here’s an overview of the Alpha hydroxy acids and why they’re effective. 

What Is Alpha Hydroxy Acid? 

Alpha hydroxy acid (AHA) is an umbrella term that regroups several types of acid that can be animal or plant-derived. Like beta hydroxy acids (BHAs) and polyhydroxy acids (PHA), AHAs are mostly known for their exfoliating capacity.  

As AHAs are water soluble, they work primarily on the skin surface, contrary to BHAS which are oil soluble and penetrate more deeply into the skin. Some of the most well-known alpha hydroxy acid examples include citric acid, tartaric acid, and malic acid, which come from fruits. Glycolic acid comes from sugar cane, while lactic acid comes from lactose or other carbohydrates but is usually synthetic. Hydroxycaproic acid is derived from royal gelly and hydroxycaprylic acid comes from animals.   

What Does Aha Do for Your Skin? 

Alpha hydroxy acid can do different things for your skin but is mostly used as an exfoliant. Exfoliation helps shed dead skin cells, leaving you with a brighter complexion. 

Among other alpha hydroxy acid benefits, it promotes collagen production and increases blood flow. It can also diminish the appearance of wrinkles and correct the discolouration of age spots and scars. Additionally, it can play an important role in reducing acne. 

Another AHA effect on the skin is that it allows better absorption of other skincare products, ensuring maximum efficiency. 

The term alpha hydroxy acid covers different types of acids. Some of these can be more effective for your specific skin type; so it’s important to ask a skincare professional. In terms of scientific research, more studies have been done for glycolic and lactic acid. These two are known to cause less irritation. 

What Are Examples of AHAs? 

Several acids fall under the category of alpha hydroxy acids. These include glycolic, citric, tartaric, lactic, hydroxycaproic, hydroxycaprylic, and malic acids.  

Glycolic and lactic acid are the best known and the most widely used. There’s solid scientific evidence backing both these types of AHAs, so it’s not surprising. According to research, these are the most effective. 

Glycolic acid comes from sugar cane while lactic acid can come from lactose or other carbohydrates. It’s often synthetic, so it’s an ideal choice for vegans. Most AHAs come from fruits, such as citric and tartaric acid. 

Also, know that alpha hydroxy acid products can come in different forms such as serums, moisturizers and toners. 

Can I Use Alpha Hydroxy Acid Every Day? 

If you are just starting out, it’s better to use it every other day, as alpha hydroxy acid side effects include irritation. However, once your skin adjusts, you can use it every day. 

It is advised to choose a product with a maximum concentration of 10%. Most serums and toners will have 5% AHA, which is a perfectly balanced level.  

While using this type of acid, it is very important to use sun protection. Since it makes your skin more sensitive, you could be more at risk of skin damage. Make sure to use quality sunscreen, even if it’s cloudy or you aren’t going outside for an extended amount of time. 

It is a powerful ingredient that anybody can technically use. However, you should ask your doctor before using it if you are pregnant or breastfeeding.  

How suitable is alpha hydroxy acid for skin conditions such as psoriasis, eczema, or rosacea? It depends on the person, so it’s best to ask a professional before using AHA. It doesn’t mean that the acid can’t be used, but a professional can advise you on the concentration and specific type of AHA that is best suited for your skin. 

The Best AHA for You 

With so many variants, AHAs (Alpha Hydroxy Acids) are a true powerhouse in skincare. With incredible exfoliating power, they can give you the brightest complexion. Remember to choose the type carefully and the correct concentration to achieve top-notch results. In case of doubt, ask your skincare professional.
