Skincare has come a long way in recent years with new technologies and ingredients. One of the most popular and potent groups of skincare ingredients is acids. They are helpful for many skin concerns, from acne and wrinkles to hyperpigmentation and uneven skin tone. But not all acids in skincare are created equal. We will explore the different types of acids used in skincare, how they work, their specific benefits, and tips on how to use them. We will also look at the expert opinion of Calypso Cavallo, a renowned skincare specialist, who will provide her insights on acids in skincare.
Alpha Hydroxy Acids (AHAs)
Alpha Hydroxy Acids, or AHAs, are a group of natural acids derived from fruits, milk, and other sources. They are known for their exfoliating properties and are used to remove dead skin cells and reveal smoother, brighter, and more youthful skin. AHAs are most commonly used to treat fine lines, wrinkles, and uneven skin tone. They also help boost collagen production, which improves the overall skin’s appearance and elasticity.
The most popular AHAs are glycolic, lactic, and mandelic acid. Glycolic acid is derived from sugar cane and is the most common AHA used in skincare. It is known for penetrating the skin deeply and effectively exfoliating. Lactic acid, derived from milk, is gentler and less irritating than glycolic acid. It is best for those with sensitive skin or new acid users. Mandelic acid, derived from almonds, is also gentle and is best for those with darker skin tones, as it can help to reduce hyperpigmentation.
Calypso Cavallo, a skincare specialist, says: “AHAs are great for exfoliating the skin and revealing a brighter, smoother complexion. They can also help boost collagen production, improving the overall appearance and elasticity of the skin. However, overuse leads to irritation and sensitivity. I recommend starting with a low concentration and gradually increasing as your skin becomes accustomed to the acid.”
Beta Hydroxy Acids (BHAs)
Beta Hydroxy Acids, or BHAs, are a group of acids derived from willow bark, salicylic acid, and other sources. They are known for their ability to penetrate deep into the pores and dissolve the build-up of oil and dead skin cells that can cause acne. BHAs are most commonly used to treat acne, blackheads, and whiteheads and are also great for those with oily or combination skin.
The most popular BHAs are salicylic acid and betaine salicylate. Salicylic acid is derived from willow bark and is the most common BHA used in skincare. It is known for penetrating deep into the pores and effectively treating acne. Betaine salicylate is a gentler form of salicylic acid and is the best for sensitive skin.
Calypso Cavallo says: “BHAs are great for treating acne and unclogging pores. They can also help to reduce the appearance of blackheads and whiteheads. They are best for those with oily or combination skin, as they can help to control excess oil production. However, over-use can lead to irritation and dryness. Salicylic acid is the most common BHA used in skincare products.”
Vitamin C
Vitamin C is a potent antioxidant protecting the skin from environmental damage. It can also help to brighten and even out the complexion and boost collagen production.
While acids benefit the skin, overusing or using the wrong type of acid can lead to irritation, redness, and dryness. It is best to start with a low concentration and gradually increase it as your skin becomes accustomed to the product. Use sunscreen to protect the skin from further damage.
Acids in skincare: conclusion
In conclusion, different types of acids in skincare can provide a wide range of benefits for the skin. From exfoliating and brightening to hydration and protection, acid can target specific skin concerns. Use the proper acid for your skin type and use it in the right concentration to avoid irritation. As Calypso Cavallo says, “Acids can be a game-changer for your skincare routine, but it’s important to use them correctly to see the best results.”
