AHAs: Reveal smoother and brighter skin
Browse all skincare products that contain AHAs now in our comprehensive DermaDB database
Alpha hydroxy acids (AHAs) are a group of water-soluble acids that are commonly used in skincare products. They work by exfoliating the top layer of dead skin cells, which helps to improve skin texture, tone, and overall appearance.
AHAs are particularly effective at treating fine lines, sun damage, and age spots, and they can also help to unclog pores and prevent breakouts.
The most commonly used AHAs in skincare products are glycolic acid and lactic acid, both of which are derived from natural sources.
What is the difference between AHAs and BHAs?
The main difference between beta-hydroxy acids (BHAs) and alpha-hydroxy acids (AHAs) is the way they work on the skin. AHAs are water-soluble acids that work by exfoliating the skin's surface, while BHAs are oil-soluble acids that work by penetrating the pores to exfoliate from the inside out.
AHAs are effective at exfoliating the surface of the skin. BHAs, such as salicylic acid, are effective at penetrating the pores to remove excess oil and unclog them.
Both AHAs and BHAs can be beneficial for the skin, and many skincare products contain a combination of both. However, people with sensitive skin or those who are prone to dryness may find that AHAs are too harsh, while those with oily or acne-prone skin may benefit more from BHAs.
What is the difference between AHAs found cleansers, moisturizers and peels?
The key difference is the concentration of AHA in each class of products. AHAs are used in cleansers at concentrations of 1%-5%, moisturizers in concentrations of 5%-10% and peels in concentrations of 20% and above.
The concentration of AHA in a moisturizer is often higher than in a cleanser because it is intended to stay on the skin longer, allowing for a more effective exfoliation. AHA in a cleanser is usually lower in concentration because it is not meant to be on the skin for an extended period of time, and too high of a concentration can cause irritation or damage to the skin. Additionally, moisturizers are formulated with other hydrating and nourishing ingredients to counteract the potential drying effects of AHAs, which can be harsh on the skin in high concentrations.
A peel is a much stronger concentration of AHAs beginning at around 20-30% for a mild peel suitable for beginners or those with sensitive skin. A peel with a higher concentration of AHAs (around 50-70%) is considered a stronger peel and it's important to note that the use of AHAs in such high concentrations should be done under the guidance of a skincare professional to prevent skin damage or irritation.

What should I keep in mind when using AHAs?
While AHAs can be very effective at improving skin appearance, they can also be irritating to some people, so it's important to start with a low concentration and gradually increase as tolerated. Additionally, it's important to wear sunscreen during the day when using AHAs, as they can increase skin sensitivity to the sun.
