Definition Of Alpha Hydroxy Acids (AHAs)
Alpha Hydroxy Acids (AHAs) are a group of naturally occurring or synthetic acids that are commonly used in skincare products to exfoliate the skin. AHAs are water-soluble, and they work by breaking down the bonds that hold dead skin cells together, allowing them to be easily shed off. revealing healthier and brighter skin.
The most commonly used AHAs in skincare products are glycolic acid (derived from sugar cane), lactic acid (derived from milk), citric acid (derived from citrus fruits), malic acid (derived from apples), and tartaric acid (derived from grapes).
AHAs are known for their ability to improve skin texture and tone, reduce the appearance of fine lines and wrinkles, and stimulate collagen production.
They are often ingredients in serums, toners, masks, and peels, and can be used by people with a variety of skin types, including sensitive skin. However, it is important to use AHAs as directed and to patch test before using them, as they can cause skin irritation if not used properly.
Brief History Of AHAs
The use of Alpha Hydroxy Acids (AHAs) in skincare can be traced back to ancient Egyptian times when women used sour milk baths to improve their skin’s texture and appearance.
In the 1800s, chemists began isolating and studying the properties of AHAs. In the 1970s, dermatologists began using AHAs to treat acne, and in the 1980s, they became widely used in cosmetic formulations.
In the early days, AHAs were primarily used for their exfoliating properties, but over time, it was discovered that they also stimulate collagen production and improve overall skin texture and tone.
Today, AHAs are commonly used in a variety of skincare products and treatments, including chemical peels, serums, toners, and masks, and they’re known for their ability to provide a wide range of benefits for skin.
The Benefits Of Using AHAs
There are several benefits of using Alpha Hydroxy Acids (AHAs) in skincare, including:
1. Exfoliation: AHAs work by breaking down the bonds between dead skin cells, which allows them to be easily sloughed off, revealing smoother, brighter skin.
2. Improved skin texture and tone: By removing dead skin cells and stimulating collagen production, AHAs can help to smooth out rough skin texture and improve overall skin tone.
3. Reduced hyperpigmentation: AHAs are known to reduce the appearance of hyperpigmentation, such as age spots and sun damage, by gently exfoliating the skin and promoting cell turnover.
4. Reduction of fine lines and wrinkles: By stimulating collagen production, AHAs can help to reduce the appearance of fine lines and wrinkles, making the skin look smoother and more youthful.
5. Improved acne-prone skin: AHAs are effective at unclogging pores and reducing the appearance of acne by removing excess oil and dead skin cells from the surface of the skin.
6. Moisturization: Some AHAs, such as lactic acid, have moisturizing properties, which can help to keep the skin hydrated and prevent dryness and flakiness.
Overall, the regular use of AHAs in skincare can lead to smoother, brighter, and more youthful-looking skin with improved texture and tone.
Types Of AHAs
Citric Acid:
Citric acid is a weak organic acid that is found naturally in citrus fruits such as lemons, limes, oranges, and grapefruits. It’s commonly used in food and beverages as a preservative, flavoring agent, and acidulant.
Citric acid is also used in skincare and cosmetic products as an alpha-hydroxy acid (AHA) to exfoliate the skin and improve its texture and appearance.
Glycolic Acid:
Glycolic acid is a type of alpha-hydroxy acid (AHA) that is derived from sugar cane. It’s commonly used in skincare products for its exfoliating properties, as it helps to remove dead skin cells and improve the texture and appearance of the skin. Glycolic acid can also help to reduce the appearance of fine lines, wrinkles, and hyperpigmentation, and can improve skin hydration by promoting the production of hyaluronic acid.
Lactic Acid:
Lactic acid is a type of alpha-hydroxy acid (AHA) that is derived from milk. It is also produced naturally by the body during exercise when muscles are working hard, and oxygen levels are low.
Lactic acid is commonly used in skincare products for its exfoliating properties, as it helps to remove dead skin cells and improve the texture and appearance of the skin. It is particularly effective for people with sensitive skin, as it is less irritating than other AHAs.
In addition to its exfoliating properties, lactic acid can also help to improve skin hydration, reduce the appearance of fine lines and wrinkles, and promote collagen production.
Malic Acid:
Malic acid is a type of alpha-hydroxy acid (AHA) that is naturally found in fruits such as apples, cherries, and grapes. It’s used in skincare products for its exfoliating properties, as it helps to remove dead skin cells and improve the texture and appearance of the skin.
Malic acid is also known for its ability to help brighten the skin, reduce the appearance of fine lines and wrinkles, and promote collagen production. In addition to its exfoliating properties, malic acid can also help to improve skin hydration and reduce the appearance of hyperpigmentation.
Tartaric Acid:
Tartaric acid is a type of organic acid that is commonly found in fruits such as grapes, bananas, and tamarinds. It’s widely used in the food and beverage industry as a flavoring agent, acidulant, and preservative.
Tartaric acid is also used in skincare products for its exfoliating properties, as it helps to remove dead skin cells and improve the texture and appearance of the skin. It’s particularly effective for people with oily and acne-prone skin, as it can help to unclog pores and reduce the appearance of blemishes.
In addition to its exfoliating properties, tartaric acid can also help to improve skin hydration, reduce the appearance of fine lines and wrinkles, and promote collagen production.
How AHAs Work
1.) Exfoliation: Alpha-hydroxy acids (AHAs) work by exfoliating the outermost layer of the skin, known as the stratum corneum. This layer is made up of dead skin cells that can make the skin look dull and rough.
AHAs, such as glycolic acid, lactic acid, malic acid, and tartaric acid, are water-soluble and can penetrate the skin easily, where they work to break down the bonds between dead skin cells.
This causes the cells to rejuvinate, revealing smoother, brighter, and more evenly toned skin. In addition to their exfoliating properties, AHAs can also help increase the production of collagen and elastin in the skin, which is responsible for keeping it firm, plump, and youthful looking.
2.) Moisturization: They can also help to improve skin hydration by promoting the production of hyaluronic acid, a natural moisturizer found in the skin. AHAs are often used in skincare products such as cleansers, toners, serums, and chemical peels.
3.) Acne & Blemish Reduction: They’re particularly effective for people with dry, dull, and aging skin, but can also benefit those with oily and acne-prone skin, as they can help with unclogging your pores and reduce the appearance of blemishes.
4.) Collagen Stimulation: AHAs stimulate collagen production by promoting the growth of fibroblasts, which are the cells responsible for producing collagen and elastin in the skin.
As we age, the production of collagen and elastin in the skin naturally declines, leading to wrinkles, fine lines, and sagging skin. AHAs work by increasing the production of these proteins, which can help to firm and plump the skin.
However, it’s important to use AHAs carefully and follow the instructions on the product, as they can cause skin sensitivity and sun sensitivity. It’s recommended to use sunscreen and limit sun exposure when using AHAs to prevent skin damage.
AHAs In Skincare
Dermatologists, doctors, and scientists have integrated AHAs into skincare in a number of ways. AHAs have been shown to be effective in treating a variety of skin conditions, including acne, hyperpigmentation, and aging skin.
They’ve also been used in professional skincare treatments, such as chemical peels, to improve the texture and appearance of the skin. In skincare products, AHAs are often used in concentrations of 5% to 10%, depending on the type of acid and the intended use of the product.
These products are typically formulated as cleansers, toners, serums, and creams, and can be used by people of all ages and skin types. In professional skincare treatments, AHAs are often used in higher concentrations to achieve more dramatic results.
Chemical peels usually have a higher concentration of AHAs in order to exfoliate the skin more deeply and stimulate collagen production. These treatments are performed by a licensed skincare professional and may require some downtime for the skin to heal and recover.
Overall, AHAs have become an important part of the skincare industry, and their effectiveness in improving the texture and appearance of the skin has been well-documented.
By promoting collagen production, increasing skin hydration, and exfoliating the skin, AHAs have become a popular choice for people seeking to improve the health and appearance of their skin.
How To Incoperate AHAs Into Your Skincare

F.A.Q.
Alpha Hydroxy Acids
AHAs (alpha hydroxy acids) are water–soluble acids that work on the surface of the skin to exfoliate dead skin cells and help to reduce the appearance of wrinkles. They are also known to help reduce the appearance of dark spots and other skin discoloration. BHAs (beta hydroxy acids) are oil–soluble acids that are able to penetrate deeper into the skin. They are primarily used to treat acne, reduce inflammation, and help to reduce the appearance of blackheads and whiteheads. BHAs are often used in combination with AHAs for optimal results.
AHAs are naturally found in fruits such as apples, grapes, oranges, and lemons. These fruits contain citric acid, which is a type of AHA. Apples, pears, and even yogurt contain malic acid, which is another type of AHA. Other natural sources of AHAs include sugar cane, red wine, sour milk, and certain types of honey.
The strongest form of AHA is glycolic acid. It has the smallest molecular size and is able to penetrate deeper into the skin than other AHAs. Glycolic acid is often used to treat wrinkles, fine lines, and hyperpigmentation. It can also help to reduce acne breakouts and improve skin texture.
AHA in skincare is an acronym for alpha hydroxy acids. AHAs are a type of chemical exfoliant that are used to remove the top layer of dead skin cells. They are often used to reduce the appearance of wrinkles, fine lines, and dark spots. AHAs can also help to reduce acne breakouts and improve skin texture.
You should not use AHA with any other exfoliating products, such as scrubs or mechanical exfoliants. You should also not use AHA with any products that contain retinol, as this can irritate your skin. Additionally, you should avoid using AHA with products that contain benzoyl peroxide as this can cause skin sensitivity.
AHAs can help to reduce acne breakouts when used in conjunction with other acne treatments. AHAs help to remove the top layer of dead skin cells, which can clog pores and cause acne. They also help to reduce inflammation, which can reduce the appearance of acne. However, AHAs are not a substitute for traditional acne treatments such as benzoyl peroxide.
Yes, AHA can cause skin purging. This is because AHAs help to remove the top layer of dead skin cells, which can lead to an increase in blemishes. This is known as skin purging, and it is temporary and will resolve once the skin has fully adjusted to the AHA.
This depends on your skin concerns. AHA is better for treating wrinkles, fine lines, and dark spots, while hyaluronic acid is better for moisturizing and plumping the skin. It is best to use a combination of both AHA and hyaluronic acid for optimal results.
