Glycolic Acid Peel: At-Home Safety Tips
What Glycolic Acid Does
Glycolic acid is the smallest alpha-hydroxy acid (AHA), which means it penetrates skin more deeply than other AHAs. It dissolves the bonds between dead skin cells, revealing fresher, brighter skin underneath. Regular use improves texture, reduces fine lines, and fades dark spots.
At-Home vs Professional Peels
- At-home products: 5-10% glycolic acid, pH 3.5-4.0, safe for regular use
- Professional peels: 20-70% glycolic acid, lower pH, require neutralization
Never attempt a professional-strength peel at home. The risk of chemical burns and permanent scarring is real.
Safe At-Home Protocol
Before the Peel
- Stop retinol/retinoids 3 days before
- Don't use if you have active breakouts or open wounds
- Do a patch test on the jawline 24 hours before
- Avoid sun exposure for at least 48 hours before
During the Peel
- Cleanse and pat skin completely dry
- Apply a thin, even layer with a cotton pad or clean fingers
- Set a timer — never exceed the product's recommended time
- If you feel intense burning (beyond mild tingling), rinse immediately
After the Peel
- Rinse with cool water
- Apply a gentle, fragrance-free moisturizer
- Avoid all actives (retinol, vitamin C, AHAs) for 3-5 days
- Wear SPF 50 daily — freshly peeled skin is extremely photosensitive
Frequency
Start with once per week at 5-7% concentration. If your skin tolerates it well after 4 weeks, you can increase to twice weekly or move up to 10%.
Warning Signs — Stop Immediately
- Intense burning or stinging that doesn't subside
- White frost (frosting) on the skin
- Swelling or blistering
- Peeling that lasts more than 5 days
