What is Glycolic Acid and How Does It Work?
Glycolic Acid is a water-soluble acid derived from sugar cane. It's the smallest AHA, meaning its molecules can penetrate the skin most effectively to work their magic.
Its main job is to dissolve the "glue" holding dead, dull skin cells on the surface. By gently un-sticking these cells, it sweeps them away, revealing the fresher, newer, and healthier-looking skin underneath.
The 5 Key Benefits of Using Glycolic Acid
Brighter, More Radiant Skin:By removing the top layer of dead cells, it instantly combats dullness.
Smoother Skin Texture:It's incredibly effective at smoothing out rough patches and unevenness.
Fades Hyperpigmentation:By speeding up cell turnover, it's a key ingredient to fade dark spots and post-acne marks.
Boosts Collagen Production:Deeper in the skin, it stimulates collagen to help firm the skin and soften fine lines.
Improves Product Absorption:With dead cells gone, your other skincare products can penetrate more deeply and work better.
How to Use Glycolic Acid Safely
This is a powerful active, so using it correctly is key to getting the benefits without the irritation.
Start Slow:Use it only 1-2 times per weekat night to start.
Don't Overdo It:Avoid using it on the same night as other strong actives like Retinoids until your skin is fully acclimated.
Listen to Your Skin:Mild tingling can be normal, but if you feel stinging or see redness, reduce the frequency.
Sunscreen is Non-Negotiable:AHAs make your skin more sensitive to the sun. You mustbe diligent with your daily broad-spectrum sunscreen.

Frequently Asked Questions (FAQ)
What's the difference between Glycolic Acid and Salicylic Acid? They are both exfoliants, but they work differently. Glycolic Acid (an AHA) is water-soluble and works on the skin's surface, making it great for dullness and texture. Salicylic Acid (a BHA) is oil-soluble and can get deep inside your pores, making it better for blackheads and acne.
Can I use Glycolic Acid with Hyaluronic Acid? Yes! They are a perfect pair. After exfoliating with Glycolic Acid, applying a Hyaluronic Acid serum will deeply hydrate your fresh new skin cells. Just apply the Glycolic Acid first, wait a minute, then apply the Hyaluronic Acid.
Final Thoughts
By introducing Glycolic Acid slowly and respecting its power, you can unlock one of the best ingredients for achieving a truly smooth, clear, and radiant complexion. Remember to always listen to your skin and protect it with sunscreen every day.
