How to Incorporate Glycolic Acid Into Your Daily Skincare

Glycolic acid has become one of the most beloved ingredients in skincare, thanks to its ability to exfoliate, smooth fine lines, and brighten the complexion. But while it offers many benefits, it’s important to use glycolic acid properly to avoid irritation and maximize results.

What Is Glycolic Acid?

Glycolic acid is a type of alpha hydroxy acid (AHA) derived from sugar cane. Its small molecular size allows it to easily penetrate the skin, making it highly effective at:

• Exfoliating dead skin cells

• Boosting collagen production

• Brightening the skin

• Fading hyperpigmentation and sun damage

• Minimizing the appearance of pores

• Preventing breakouts

Because of its versatility, glycolic acid is often found in a wide range of over-the-counter (OTC) and professional skincare products, including cleansers, toners, serums, and chemical peels.

How Glycolic Acid Works

Glycolic acid breaks down the bonds between dead skin cells, helping them shed more easily and allowing fresh, healthy skin to surface. It also stimulates collagen production, which supports firmer, plumper skin. As we age, natural collagen production slows, and glycolic acid can help counteract this decline.

Best Practices for Using Glycolic Acid

To enjoy the full benefits of glycolic acid while protecting your skin, follow these essential guidelines:

1. Always Wear Sunscreen

Glycolic acid increases your skin’s sensitivity to the sun, making daily sun protection non-negotiable. Use a broad-spectrum sunscreen with at least SPF 30 every day, even if you aren’t spending much time outdoors.

2. Start Slowly

Introduce glycolic acid gradually into your routine. Start by using it 2–3 times a week. If your skin tolerates it well, you can increase the frequency to daily use. If you experience irritation or redness, reduce the frequency or take a break before resuming.

3. Avoid Mixing With Certain Products

Glycolic acid should not be combined with other potent exfoliants or treatments that can irritate the skin, such as:

• Retinoids (tretinoin, adapalene)

• Salicylic acid

• Benzoyl peroxide

• Other chemical peels

If you're under a dermatologist's care or already using prescription skincare products, consult your provider before adding glycolic acid to your regimen.

4. Be Patient

Results with glycolic acid aren’t instant. You may notice some roughness or mild flaking initially as your skin adjusts. Stick with the routine, and within a few weeks, you’ll likely see smoother, more radiant skin.

Does Glycolic Acid Help With Scars?

While glycolic acid can lighten dark spots left by acne or wounds and improve skin texture, it cannot remove deep scars. Professional treatments like stronger chemical peels, laser therapy, or microneedling may be more effective for scar reduction.

Where to Find Glycolic Acid

You can easily find glycolic acid products at drugstores, beauty retailers, and online. Options include:

• OTC products: Typically contain 5–10% glycolic acid

• Professional peels: Performed by dermatologists or estheticians, containing 30–70% glycolic acid for more dramatic results

Choosing the Right Product

When selecting a glycolic acid product, consider:

• Your skin type: Sensitive skin may do better with lower concentrations.

• Product strength: Higher percentages work faster but may increase irritation risk.

• Product pH: Though not always listed, a lower pH enhances the acid’s effectiveness.

A dermatologist can guide you in choosing the most appropriate formulation based on your skincare needs and goals.

Safety Tips and Precautions

While generally safe, glycolic acid may cause:

• Mild irritation

• Redness

• Dryness

• Flaking

To minimize side effects:

• Use a gentle cleanser and moisturizer alongside glycolic acid.

• Avoid over-exfoliation.

• Apply sunscreen daily.

• Stop use if severe irritation occurs and consult a healthcare professional.

The Takeaway

Glycolic acid is a powerful addition to any skincare routine, offering numerous benefits from improved texture to a brighter, more youthful complexion. With proper use and precautions, you can safely incorporate glycolic acid and enjoy its skin-transforming effects.
