If you’re interested in skincare, there’s not a chance you haven’t come across glycolic acid. It’s one of the most widely celebrated ingredients for glowing, brighter, and smoother skin.
But how exactly does it work? Who should use it? And what makes glycolic acid special?
Hi, I’m Kim Gallo, a licensed esthetician with over 20 years in the skincare industry. Today, I’m here to break down everything you need to know about this powerhouse ingredient. By the end of this guide, you’ll be equipped to decide whether glycolic acid deserves a spot in your skincare routine.
What is Glycolic Acid?
Glycolic acid is part of a group of ingredients known as Alpha Hydroxy Acids (AHAs). AHAs are naturally derived from foods, but glycolic acid is particularly sourced from sugarcane.
What makes glycolic acid stand out? Its small molecular size. It’s the smallest of all AHAs, meaning it can penetrate your skin more deeply, making it highly effective at exfoliating and improving skin texture. But don’t worry, we’ll go into how to use it safely later in this post.

How Glycolic Acid Works on the Skin
Here’s what happens when you apply glycolic acid to your skin:
It loosens the bonds between dead skin cells on the surface of your skin.
These dead cells then shed away, revealing the fresh, new skin underneath.
Over time, it works beneath the surface to stimulate collagen production, which improves firmness and texture.
It’s this exfoliating and collagen-boosting combo that gives glycolic acid its star reputation in skincare.
Benefits of Glycolic Acid for Your Skin
What can glycolic acid do for your skin? Plenty! Here’s why it’s a staple in so many skincare routines.
1. Exfoliation for Brighter Skin
By removing dead skin cells, glycolic acid uncovers fresh, radiant skin. Gone are the days of dullness; hello, youthful glow!
2. Fading Hyperpigmentation and Dark Spots
If you’ve struggled with uneven skin tone or post-acne marks, glycolic acid can help fade those imperfections over time.
3. Boosts Collagen for Anti-Aging Results
Collagen is your skin’s support system, but production slows with age. Glycolic acid stimulates collagen, reducing fine lines and giving your skin a firmer feel.
4. Enhances Skin Texture
Are rough patches or uneven texture bothering you? Glycolic acid smooths and softens your skin for that silky finish.
5. Improves Product Absorption
By clearing out layers of dead skin, glycolic acid allows serums and moisturizers to penetrate better, amplifying their effectiveness.
6. Unclogs Pores for Clearer Skin
Struggling with blackheads or acne? Glycolic acid deep cleans your pores and prevents buildup, reducing breakouts in the process.

Possible Side Effects and Risks of Glycolic Acid
While glycolic acid has incredible benefits, knowing how to use it properly is key to avoiding irritation.
Increased Sun Sensitivity
Since glycolic acid removes surface cells, it can make your skin more susceptible to UV damage. Always wear sunscreen (SPF 30 or higher) when using this ingredient.
Redness or Irritation
If you’re new to glycolic acid or have sensitive skin, you might experience mild redness or tingling. Start at a lower concentration and work your way up gradually.
Overuse Can Damage Your Skin Barrier
Using glycolic acid too often or at high concentrations can compromise your skin barrier, leading to dryness or sensitivity. Moderation is key.
Allergic Reactions
Although rare, some people can have an allergic reaction to glycolic acid. Always patch-test before introducing it into your routine.
How to Use Glycolic Acid in Your Skincare Routine
If you’re ready to incorporate glycolic acid into your skincare routine, follow these steps for the best results.
1. Choose the Right Product
Glycolic acid comes in many forms, from cleansers and toners to serums and peels.
Cleansers offer a gentle, rinse-off introduction to glycolic acid.
Toners provide a deeper treatment and prep your skin for other products.
Serums offer high concentrations for targeted results.
2. Start Slow
Begin with a 5–10% concentration if you’re a first-time user. You can increase to 15%+ over time if your skin tolerates it well.
3. Pair It With Hydrating Products
To balance its exfoliating effects, layer glycolic acid with hydrating ingredients like hyaluronic acid or a rich moisturizer.
4. Avoid Conflicting Ingredients
Steer clear of pairing glycolic acid with strong actives like retinol or vitamin C in the same routine.

5. Best Time to Apply
Glycolic acid is great for nighttime use when your skin is in repair mode. If you use it during the day, don’t forget the SPF!
How to Choose the Right Glycolic Acid Treatment
Everyone’s skin is unique, so consider your skin type and concerns when choosing a product.
Is Glycolic Acid Right for You?
It works wonders for oily and combination skin, but those with dry or sensitive skin should proceed with caution. Start with a lower concentration and gradually increase as your skin adjusts.
At-Home vs. Professional Treatments
At-home glycolic acid treatments can be effective for mild exfoliation and maintenance, but professional treatments offer deeper penetration and more dramatic results.
At-Home Options: Look for over-the-counter products like cleansers, toners, and serums.
Professional Treatments: Chemical peels can deliver faster results with stronger concentrations of glycolic acid. If you’re in Naples, learn more about my Chemical Peels.
Understanding Labels and Concentrations
Always check the label for concentration percentages and ensure the product matches your experience level.

Tips for Incorporating Glycolic Acid Safely
Now that you know some of the best glycolic acid products on the market, here are a few tips for incorporating them safely into your skincare routine:
Start slow: If you’re new to using glycolic acid, start with a low-concentration product and slowly increase the percentage as your skin builds tolerance. Too much too soon can lead to irritation.
Use in moderation: While daily use is safe for some individuals, it’s best to listen to your skin and adjust accordingly. Some may only need to use glycolic acid once or twice a week.
Always follow with moisturizer and sunscreen: Glycolic acid can make your skin more sensitive to the sun, so it’s important to always apply sunscreen and follow with a moisturizer to keep your skin hydrated.
Consistency is key: For best results, incorporate glycolic acid into your skincare routine consistently. This will allow the product to work effectively and provide long-term benefits for your skin.
Consider using at night: Some individuals prefer to use glycolic acid at night because it can cause some mild redness or irritation initially. This way, you can give your skin time to recover while you sleep.
Patch test before using on larger areas: As with any new skincare product, it’s important to patch test first on a small area of your skin before applying all over your face. This will help determine if you have any adverse reactions to the product.
Consult with a professional: If you have sensitive skin or are unsure about using glycolic acid, it’s always best to consult with a dermatologist or skincare expert before incorporating it into your routine. They can provide personalized advice and recommend the best products for your specific skin concerns.
Sun protection is key: Glycolic acid can make your skin more sensitive to the sun, so it’s crucial to wear sunscreen every day when using this product. Look for a broad-spectrum sunscreen with at least SPF 30 to protect your skin from harmful UV rays.
Avoid mixing with other active ingredients: To avoid potential irritation, it’s best to use glycolic acid on its own and avoid layering it with other active ingredients like retinol or vitamin C. If you want to incorporate multiple active ingredients into your skincare routine, it’s best to use them on alternate days.
When to Seek Professional Advice
If you’re not seeing results or are experiencing side effects, it might be time to consult a professional.
An esthetician, like myself, can help assess your skin type and recommend the best course of action for incorporating glycolic acid into your skincare routine. We can also guide you on how to properly use and layer the product for maximum effectiveness.
It’s important to remember that everyone’s skin is unique and what works for one person may not work for another. Seeking professional advice can help tailor your skincare routine to your specific needs and ensure you’re using glycolic acid safely and effectively.
