AHAs And BHAs Decoded: How The Chemical Exfoliants Work, Key Differences, And More

Chemical exfoliants like AHAs and BHAs have transformed skincare routines with their ability to scrub off the skin gently, unlike scrubs with abrasive particles. If your dream is radiant, smooth, and nearly poreless skin, it's time to understand what AHAs and BHAs bring to the table.

Alpha-hydroxy acids (AHAs) exfoliate the dead skin cells from the surface of the skin, which reveals a brighter and more even complexion. Beta-hydroxy acids (BHAs) penetrate deeper into the pores to clear up buildup and fight breakouts. This AHA vs. BHA dynamic makes them powerful allies for achieving glowing, bump-free skin.

However, it’s crucial to choose the right formula for your skin type and use these exfoliants properly, as incorrect application may lead to irritation. Whether you’re learning what a BHA is or looking to elevate your exfoliation routine, AHAs and BHAs are the ultimate game-changers. Gritty scrubs, step aside.

What Are AHAs?

AHAs, or alpha-hydroxy acids, are a group of exfoliating chemicals that naturally occur in sources like sugarcane (glycolic acid), milk (lactic acid), and fruits (citric acid). While originally derived from these natural ingredients, most AHAs in modern cosmetic formulations are lab-synthesised to ensure consistency and safety.

These skincare superstars have gained immense popularity over the last decade for the reason of being able to treat almost all signs of ageing like fine lines, wrinkles, discolouration, and photoaging. It's effective because they dissolve very gently the bonds holding the dead skin cells together so that cell turnover can occur, and fresher and smoother skin can be revealed underneath.

AHAs are not only effective but also versatile, making them suitable for a wide range of skin types and concerns. They help refine skin texture, brighten dull complexions, and even out pigmentation. Beyond ageing skin, AHAs are also great for acne-prone individuals, as they unclog pores and promote clarity.

When using AHAs, begin with a low concentration and gradually increase tolerance to avoid irritation. AHA use must always be combined with sunscreen, as it increases your skin's sensitivity to the sun. If used regularly, AHAs can make your skin glow and rejuvenate.

Types Of AHAs

Although there are several species of alpha-hydroxy acids, lactic acid and glycolic acid are found to be the most abundantly used in products. There is a common combination where both these two powerhouse ingredients can be used to supply multiple benefits for the skincare regime. For example, the Wishcare 10% body lotion pairs glycolic and lactic acids to enhance turnover on the surface of cellular skin, leaving it highly smoother and brighter. Other AHAs, including citric acid, mandelic acid, malic acid, and tartaric acid, work to contribute much to the healthiness of the skin.

Lactic Acid: One of the most commonly used alpha hydroxy acids, known for its ability to be an exfoliant while hydrating skin. Due to its capability to trigger the shedding off dead layers of skin cells, thus enhancing skin's texture and softness along with reducing roughness once applied routinely. Moreover, lactic acid is an important ingredient in the skin's natural moisturising factor (NMF) that helps retain moisture and hydrates the skin. Products such as The Ordinary Lactic Acid 10% + HA contain lactic acid that provides relief and hydration for clearer, softer skin.

Nykaa Recommends:

Glycolic Acid: Glycolic acid is considered one of the most potent AHAs since it is a very small molecule, allowing it to penetrate the skin much deeper. It smoothens the texture of the skin, reduces pores, and facilitates exfoliation. Present in The Derma Co 7% Glycolic Acid Hydrating Toner it is combined with hyaluronic acid that gently helps exfoliate, hydrates skin, and enhances overall skin clarity. The formula also includes three essential ceramides to restore the skin's protective barrier and niacinamide to soothe and calm irritation.

Incorporating AHAs such as lactic and glycolic acid into your skincare routine can change the texture and radiance of your skin, making them essential components of effective skincare regimens.

What Are BHAs?

What is a BHA? BHAs, or beta-hydroxy acids, are chemical exfoliants used in a wide variety of skincare treatments for their excellent benefits. Unlike alpha-hydroxy acids (AHAs), which are water-soluble, BHAs are oil-soluble and can penetrate deeper into pores. This makes them great for a wide range of skin issues, including acne, blackheads, and rough texture, and even conditions like psoriasis and seborrheic dermatitis.

Generally derived from sources that include willow bark and sweet birch, BHAs are frequently manufactured synthetically for more consistency and stability in cosmetic formulations. Probably the most common BHA used in skincare products, salicylic acid, is recognised for its great anti-inflammatory and antibacterial properties. It is consequently a highly sought-after component for treating oily and problematic skin.

BHAs are excellent beyond treating acne. They help to smoothen bumpy skin and improve the general skin texture. They do this by breaking the bonds holding dead skin cells, therefore promoting cell turnover, with fresh, healthy skin under it. Their oil-soluble nature also makes them perfect for decongesting clogged pores and reducing excess sebum. With the BHAs, start with slow inclusions to avoid over-exfoliation and then end with sunscreen application because these can make your skin highly sensitive to sunlight. Using BHAs regularly may alter the clarity and texture of your skin.

Types of BHAs

Beta Hydroxy Acids (BHAs) are a skincare powerhouse, respected for their ability to transform your complexion. Unlike AHAs, BHAs are oil-soluble, which means they penetrate deeply into your skin to unclog pores, reduce acne, and refine uneven texture. Curious about the different types of BHAs and what they can do for your skin? Here’s everything you need to know:

Salicylic Acid: Salicylic acid is the most effective BHA, famous due to its acne-fighting abilities. It is commonly obtained from willow bark. It works by making your pores dissolve excess oils and dead skin cells; hence, it is known to be an anti-inflammatory product, which is greatly in demand for those troubled with blackheads, whiteheads, or stubborn outbreaks. In addition to maintaining acne control, it would help reduce redness while preventing future blemishes.

Betaine Salicylate: For gentle, sensitive skin that is ready for gentle exfoliation, betaine salicylate is like an answer to a dream. It's a gentler alternative to salicylic acid, sourced from sugar beets, for effectively clearing pores without irritating skin. It's for first-timers who just got started with chemical exfoliants or those seeking maintenance of a calm and hydrated complexion while still taking full advantage of BHAs.

Nykaa Recommends:

Tropic Acid: This is a little less known but increasingly found in skincare. Similar exfoliating and acne properties to salicylic acid, this is particularly used for individuals who want balance in the treatment of BHAs.

The Difference Between AHAs vs BHAs

In the skincare realm, AHAs or Alpha Hydroxy Acids, and BHAs, or Beta Hydroxy Acids, are the undisputed exfoliation monarchs. However, this is where knowing their distinction comes in to reveal a radiant, selfie-perfect glow. So, here's the deal, classy and straightforward!

AHAs

Alpha Hydroxy Acids are water-soluble exfoliants that come from natural sources, such as sugar cane, milk, or fruits. Think glycolic acid, lactic acid, or mandelic acid. These AHAs work their magic on the surface of your skin, dissolving dead skin cells to reveal a brighter, smoother complexion. AHA is the perfect solution to issues like dry or dull skin that is craving hydration and brightness, uneven skin texture or tone, or dark spots. AHAs are best for resurfacing and giving your skin that fresh, baby-soft glow. Bonus? They stimulate collagen production, making them the go-to for any anti-ageing skincare routine.

BHAs

Beta Hydroxy Acids, like salicylic acid, are oil-soluble, allowing it to penetrate deep into layers of skin. BHAs exfoliate inside pores helping clear congestion, reduce blackheads, and prevent acne. It's mostly used to tackle skin issues like oily or acne-prone skin or enlarged pores and stubborn breakouts. BHAs are all about unclogging pores and controlling excess oil without stripping the skin. They're gentle yet powerful for those dealing with persistent blemishes or uneven skin texture.

Which One Should You Choose?

It's not a competition, it's about your skin's needs. For dry or mature skin, AHAs deliver hydration and radiance. For oily or acne-prone skin, BHAs are your blemish-busting besties. Can't decide? Many products now combine both for a balanced exfoliation game.

Should You Use AHA, BHA Or Both?

The buzz about AHAs (alpha hydroxy acids) and BHAs (beta hydroxy acids) is undeniable when it comes to exfoliating your skin. But which one is right for you? Or should you use both? Let's break it down.

AHAs are water-soluble acids that are extracted from fruits and milk, making them ideal for surface exfoliation. They do an excellent job on dry or sun-damaged skin to remove dead skin cells and enhance radiance. When your complexion feels rough, dull, or uneven, AHAs can brighten it up with consistent use, which makes them ideal for normal to dry skin types.

On the flip side, BHA are easily dissolvable because they are capable of entering deeper pores for the dissolution of oils and other types of debris. Salicylic acid is probably the best-known BHA, particularly for individuals with acne issues or oily pores. These are usually great for dealing with pores, especially with oily skin.

Now, comes the question, do both? The answer is a resounding: it depends upon your skin type and needs. If you need your skin to be smooth and hydrated, AHAs can do that. However, if you have acne breakouts or too much oil, BHAs will help. Using both together can give a powerhouse routine; however, this should be done in moderation and at intervals to prevent irritation.

Remember: the usage of AHAs and BHAs increases sun sensitivity; wear sunscreen.

How Are AHAs and BHAs Different From Physical Exfoliants?

When it comes to exfoliating your skin, the sea of options can become overwhelming, all those AHAs and BHAs as well as physical exfoliants promise smooth, radiant skin. But what's the difference, really? Which is best suited for you? Let's break it down.

AHAs vs. BHAs

AHAs (alpha hydroxy acids) and BHAs (beta hydroxy acids) are chemical exfoliants that work differently than physical exfoliants. AHAs, for example, glycolic and lactic acids, are water-soluble and mostly work on the surface of the skin, making them ideal for people with dry or sun-damaged skin. They break down the bonds between dead skin cells, leaving a brighter, smoother complexion.

BHAs, such as salicylic acid, are oil-based, meaning they can travel deep within pores, making them beneficial to users of oily or acne-prone skin, as they help dissolve debris, oil, and dead skin trapped in pores that can create breakouts.

Physical Exfoliants

Unlike their chemical cousins, physical exfoliants rely on grit or texture in scrubs or brushes to rub away dead skin. These immediately produce results, but are far too harsh for sensitive skin and may cause microtears when used with the slightest degree of force.

The Verdict

For deeper, more refined exfoliation without causing irritation, you can turn to AHAs and BHAs for the softest, most gentle control. When your skin is craving a bit more texture, reach for the physical exfoliants, these acid powers will get your skin glowing for sure.

Conclusion

In conclusion, understanding what is AHA and what is a BHA can transform your skincare routine. Whether you choose AHA vs BHA depends on your skin’s needs, AHA for surface exfoliation or BHA for deep pore cleansing. Now that you know what AHA and BHA can do, you’re ready to embrace these acids for flawless, glowing skin.
