Azelaic acid and glycolic acid: which is better for exfoliation?

Introduction to Azelaic Acid and Glycolic Acid

As a skincare enthusiast, I'm always on the lookout for the best exfoliating ingredients to keep my skin looking fresh and radiant. Two popular ingredients that have caught my attention recently are azelaic acid and glycolic acid. In this article, I'll be comparing these two superstar acids to determine which one is better for exfoliation.

What is Azelaic Acid?

Azelaic acid is a naturally occurring compound found in grains such as wheat, rye, and barley. It has been gaining popularity in the skincare world due to its numerous skin benefits, including its exfoliating properties. Azelaic acid works by breaking down the bonds between dead skin cells, allowing them to be easily removed from the skin's surface. This helps to unclog pores, reduce inflammation, and improve overall skin texture.

What is Glycolic Acid?

Glycolic acid, on the other hand, is an alpha-hydroxy acid (AHA) derived from sugarcane. It has become a skincare staple for its powerful exfoliating properties, which help to remove dead skin cells and reveal a brighter, more even complexion. Like azelaic acid, glycolic acid works by breaking down the bonds between dead skin cells, making it easier for them to be swept away.

Exfoliation Power: Azelaic Acid vs Glycolic Acid

Now that we know a little more about these two acids, let's compare their exfoliating abilities. Glycolic acid is considered a stronger exfoliant due to its smaller molecular size, which allows it to penetrate more deeply into the skin. This makes it particularly effective at treating issues such as dullness, hyperpigmentation, and uneven skin tone. However, this also means that glycolic acid can be more irritating to sensitive skin types.

Azelaic acid, on the other hand, is a gentler exfoliant, making it a safer option for those with sensitive or reactive skin. While it may not offer the same level of exfoliation as glycolic acid, it still provides noticeable improvements in skin texture and clarity over time.

Skin Benefits Beyond Exfoliation

Both azelaic acid and glycolic acid offer additional benefits beyond their exfoliating properties. Azelaic acid is known for its ability to reduce inflammation and redness, making it an excellent option for those with acne-prone or rosacea-prone skin. It has also been shown to inhibit the production of melanin, which can help to fade hyperpigmentation and even out skin tone.

Glycolic acid, meanwhile, has been found to stimulate collagen production, which can help to improve skin elasticity and reduce the appearance of fine lines and wrinkles. It also has some hydrating properties, making it a good choice for those with dry or dehydrated skin.

Choosing the Right Acid for Your Skin Type

When deciding between azelaic acid and glycolic acid, it's crucial to consider your individual skin type and concerns. If you have sensitive or reactive skin, azelaic acid may be the better choice for you, as it is less likely to cause irritation. Additionally, if you're dealing with acne, rosacea, or hyperpigmentation, azelaic acid's unique benefits may make it the more suitable option.

On the other hand, if your main concern is dullness, uneven skin tone, or signs of aging, glycolic acid may be the more effective exfoliant for you. Just be sure to start with a lower concentration and gradually increase it as your skin becomes more accustomed to the acid.

How to Incorporate Azelaic Acid or Glycolic Acid into Your Skincare Routine

Once you've determined the best acid for your skin concerns, it's time to incorporate it into your skincare routine. Both azelaic acid and glycolic acid can be found in various product formulations, such as cleansers, toners, serums, and creams. Start by introducing the acid of your choice in one product, and monitor your skin's reaction before adding more products containing the ingredient.

Remember to always use sunscreen when using exfoliating acids, as they can increase your skin's sensitivity to the sun. It's also a good idea to alternate the days you use your exfoliating acid with other active ingredients, such as retinol or vitamin C, to avoid overloading your skin and causing irritation.

Can You Use Azelaic Acid and Glycolic Acid Together?

While it's generally not recommended to combine multiple exfoliating acids in the same skincare routine, some people may find that using both azelaic acid and glycolic acid works well for their skin. If you decide to experiment with this combination, it's essential to start slowly and monitor your skin for any signs of irritation or sensitivity. You may also want to consider using one acid in the morning and the other in the evening to minimize the risk of over-exfoliation.

Final Thoughts on Azelaic Acid vs Glycolic Acid

In conclusion, both azelaic acid and glycolic acid are effective exfoliants that offer unique benefits for different skin concerns. Ultimately, the best choice for your skin will depend on your individual needs and sensitivities. Just remember to patch test any new products, introduce acids slowly, and always wear sunscreen to protect your freshly exfoliated skin. Happy exfoliating!

I've been using 20% azelaic acid for rosacea and honestly? It's been a game-changer. No redness, no burning, just smoother skin over time. Glycolic? I tried it once and my face looked like a tomato for three days. Not worth it for sensitive types. Stick with azelaic if you're prone to irritation.

Let’s be clear: glycolic acid is the only true exfoliant here. Azelaic acid is a glorified anti-inflammatory with *mild* keratolytic properties-barely even qualifies as exfoliation. Anyone who calls it equivalent is either misinformed or has never used a 10% glycolic peel. The molecular weight difference alone makes this a no-brainer. If you’re not seeing visible sloughing, you’re not exfoliating-you’re just moisturizing with a fancy ingredient.

Y’all are overcomplicating this 😅 Azelaic = chill vibes for acne + redness. Glycolic = glow-up machine for dull skin. Use both if your skin can handle it-just don’t mix in the same step. I use azelaic AM, glycolic PM, sunscreen ALWAYS. My skin’s been glowing since 2021. 🌟

Have you all considered that the skincare industry is just pushing these acids to keep you buying? Azelaic acid is naturally found in grains-why is it only sold in $80 serums? And glycolic? Derived from sugarcane, yet somehow we’re told to apply it to our faces like it’s liquid gold. I think Big Skincare is manipulating us into thinking we need chemical peels to be worthy. My grandma washed her face with oatmeal and lived to 98. Coincidence? I think not.

The assertion that azelaic acid is a ‘gentle exfoliant’ is technically inaccurate. While it does possess some desquamative effects, its primary mechanism is antimicrobial and anti-angiogenic. To classify it as an exfoliant on par with glycolic acid, an alpha-hydroxy acid with well-documented keratolytic activity, is a fundamental misrepresentation of dermatological pharmacology. One should not conflate modulatory effects with direct exfoliation.

I tried glycolic for a week. My skin peeled so bad I looked like a snake. Then I tried azelaic and nothing happened. So I stopped. Now I just wash with water. Who needs fancy chemicals? You’re all just scared of your own skin. This whole post is a scam to sell more products.

I use both, but not on the same day. Azelaic in the morning for my redness, glycolic twice a week at night. My skin doesn’t burn, doesn’t peel, just looks healthier. Start slow. Listen to your skin. You don’t need to go hard to get results.

^^^ this. Also, if you're using glycolic and still getting breakouts, maybe your skin is too sensitive for it. Azelaic doesn't just exfoliate-it calms the whole party. Try it before you burn your face off again. 🙏✨
