AHA Vs. BHA

The skin is constantly renewing itself, with cells dying and new ones taking their place. But as we age, the process slows down. Wrinkles start to appear and our skin gets dryer. That’s where chemical exfoliants come in. They help remove dead cells that accumulate on the surface of your skin which can clog pores, cause acne, rough skin texture and dull skin. There are a few different types of exfoliants, but today we’re going to focus on the most popular two: Salicylic acid (BHA) and Glycolic Acid (AHA). You’ve probably seen them in skincare products but may not know exactly what they do. So today we’re comparing Salicylic acid Vs Glycolic acid and answering all your questions about the differences between the two.

Many people wonder “are glycolic acid and salicylic acid the same?” and while they sound very similar, they are very different. They do share some similarities in what they do (exfoliate the skin) but each have their own unique benefits that make them more appropriate for certain skin types of conditions.

What Is The Difference In Salicylic Acid And Glycolic Acid?

salicylic acid and glycolic acid differences

In order to compare Salicylic Acid Vs. Glycolic Acid, we’ll take a look at these chemical exfoliants individually and see what they do best, benefits and who should use them.

What Is Salicylic Acid (BHA)?

Salicylic Acid (BHA) is a chemical exfoliant that can be found naturally in some plants such as willow bark. It’s an oil-soluble exfoliant which means it is able to penetrate your pores and clear away the stuff that’s clogging them up. This makes it great for those with acne, clogged pores, blackhead, sebaceous filaments and oily skin.

Salicylic acid works by loosening the attachments between cells, so they can be loosened and exfoliated away. BHA’s not only help remove dead skin cells, but also can travel deep into the pores to unclog them in a way that glycolic acid can’t.

Salicylic Acid Is:

  • Anti-bacterial – kills acne causing bacteria to help treat and prevent acne
  • Anti-inflammatory – reduces redness associated with breakouts, calms irritation and reduces inflammation in the skin (like cystic acne)
  • Oil-soluble – cuts through oil to travel deep into the pores to kill bacteria, remove clogged pores and regulates oil production

Salicylic Acid Benefits:

  • Treats active acne – salicylic acid works to decrease inflammation from pimples and helps heal active breakouts so they go away quicker
  • Prevents acne – not only does BHA treat active acne, but it also kills acne causing bacteria and unclogs pores which prevent acne from forming in the first place
  • Smooths skin – since salicylic acid helps to unclog pores, it also helps with textural issues like closed comedones and rough skin texture caused by dead skin cell build up
  • Decreases oil production – BHA can help prevent your skin from producing excess oil
  • Minimizes pores – since BHA removes all the gunk in your pores, they will appear smaller

What Is Glycolic Acid (AHA)?

Glycolic acid is an Alpha Hydroxy Acid that comes from sugar cane. It’s the smallest AHA which means it’s able to penetrate your skin easily to help with cell renewal and exfoliation. This makes it great for dry, dull skin, uneven texture, fine lines, wrinkles and sun damage.

Glycolic acid works by breaking up the bonds that hold skin cells together. When skin cells die, they sometimes want to stick around on the skin, which can cause a build up of dead skin. Glycolic acid works by breaking these bonds so they dead skin cells cannot hang on and effectively swept away, leaving smooth, radiant skin behind. Glycolic acid works on the surface of the skin, while salicylic acid works at a deeper level.

Glycolic Acid Is:

  • Hydrating – AHA’s have humectant properties which means they help hydrate the skin
  • Anti-bacterial – kills acne causing bacteria to help treat and prevent acne
  • Collagen stimulating – by stimulating fibroblasts in the skin to produce collagen

Glycolic Acid Benefits:

  • Brightens skin tone – as AHA speeds up cell turnover, it reveals new, healthy skin cells for a brighter complexion
  • Fades hyperpigmentation – glycolic acid is known for its ability to fade hyperpigmentation like acne scarring, dark spots and sun spots
  • Anti-aging – glycolic acid plumps skin to diminish fine lines and wrinkles and also helps to stimulate collagen production
  • Smooths skin texture – AHA works to remove dead skin cell build up that causes rough skin, so it smooths out texture issues as well as any clogged pores
  • Prevents acne – glycolic acid removes dead skin cell build up so they don’t get trapped in your pores and lead to acne

Salicylic Acid Vs Glycolic Acid For Skin

Now that we’ve gone over the major differences between bha vs aha, let’s take a look at which one is best to use for certain skin conditions.

Salicylic Acid Vs Glycolic Acid For Skin Types

Both glycolic acid and salicylic acid are great options for those with acne-prone skin because they can help to clear pores. Out of the two, BHA is best for those with acne, blackheads or oily skin.

For people with dry skin, AHA will be the way to go because of the hydrating properties of AHA’s.

For those with sensitive skin, AHA’s like lactic or mandelic acid or PHA’s will be best as they are larger in size and therefore more gentle.

Salicylic Acid Vs Glycolic Acid For Acne

Salicylic Acid is best to use for acne because BHAs are oil soluble meaning it can penetrate sebum filled pores more deeply than AHA’s and reduce clogged pores that can lead to acne. Although AHA’s are also antibacterial and can help prevent dead skin cells from clogging up your pores, it’s also a great choice for acne. In some cases, you may need both AHA and BHA to get rid of acne completely. But if you want to stick with just one, go with the BHA. You can always add the AHA in your routine later if you need a little more acne-fighting (we all know how tough acne can be!).

Salicylic Acid Vs Glycolic Acid for Hyperpigmentation

Glycolic acid is best for hyperpigmentation, sun spots and acne scarring. AHA’s are known for their ability to work on the surface of the skin and therefore help with fading hyperpigmentation.

Salicylic Acid Vs Glycolic Acid For Keratosis Pilaris

Is AHA or BHA better for treating chicken skin? For those with keratosis pilaris, an AHA like glycolic acid will be the best option because it breaks down the bonds in skin that causes dead cells to stick together. However, BHA can be helpful to cut through the oil on the skin and travel deep into the pores and hair follicles to unclog. If you really want to tackle Keratosis Pilaris, use both AHA and BHA.

Salicylic Acid Vs Glycolic Acid For Ingrown Hairs

Both! Use a product with AHA and BHA to tackle dead skin and bacteria that contribute to ingrown hairs.

Salicylic Acid Vs Glycolic Acid For Closed Comedones

Closed comedones are also known as whiteheads, and they’re where a clog has formed underneath the skin’s surface. This clog doesn’t lead to a pimple with a head, but it may turn into acne over time if not treated. For closed comedones, or skin colored bumps, salicylic acid will work best because it can travel deep into the pore to clear it out.

Is Glycolic Acid Better Than Salicylic Acid?

One is not better than the other, but one will give better results depending on your skin type and skin concerns. Although they are both chemical exfoliants, BHA’s are better at targeting certain things like acne, blackheads and oily skin, while AHA’s are better at fading hyperpigmentation, anti-aging and skin texture.

Can I Use Glycolic Acid And Salicylic Acid Together?

salicylic acid vs glycolic acid for blackheads

Yes, you can use salicylic acid and glycolic acid together without issue. In fact, many products on the market contain both AHA and BHA and give incredible results. If you’re wanting to target a range of skin concerns or just want to simplify your skincare routine, look for products with both salicylic and glycolic acid.

How Do I Use Glycolic Acid And Salicylic Acid?

Wanting to know how to use glycolic acid and salicylic acid together in your skincare routine? Exactly where do these goods fit into your regimen? It all depends on the sort of product you’re using. AHA and PHA chemicals can make your skin more sensitive to sunlight, so apply them at night. BHA chemicals, on the other hand, may be used in either the morning or evening.

Where you use them in your routine all depends on the kind of product again. In general, you should apply skincare products in layers according to their thickness. That is, whatever has the thinnest consistency goes first, followed by the second thickest, and so on.

Here’s an example routine for clarification:

Cleanser > AHA Toner > BHA Serum > Hydrating Serum > Moisturizer

Can I Use Glycolic Acid and Salicylic Acid At The Same Time?

Yes, you can use AHA and BHA at the same time, one right after another. Many products on the market contain a blend of AHA and BHA, so it’s perfectly safe to use both. However, do be careful if you are new to chemical exfoliants! Be sure to hydrate and moisturize your skin properly and don’t overdo it!

Glycolic Acid Vs Salicylic Acid Vs Hyaluronic Acid

Since there are so many different acids in skincare, it’s easy to get them confused. Although it may sound like it, hyaluronic acid is not an exfoliant. It’s a hydrating ingredient that can hold onto water, which plumps and hydrates skin. There’s no exfoliation when you use hyaluronic acid, but it can help acne in another way!

How Often To Use AHA and BHA Products

So, how often should you be using an AHA or BHA product? It all depends on your skin. If you have never used a chemical exfoliant before, plan to start off slow by only using it once or twice a week. Then gradually increase to 3-4x a week. Many people can use chemical exfoliants everyday, while others can only use them a couple times a week.

When it comes to chemical exfoliants, your skin will tell you if it can handle a certain type of product. If redness or irritation occurs after use, stop using the product and get your skin calmed down before introducing it back into your routine.
