Buying Guide
Pro Tip: Make Your Exfoliant Work Harder (Without Irritating Your Skin)
Use less product than you think. With leave-on acids, more is not better. A thin, even layer is enough to coat the areas that clog (usually the T-zone). If your skin feels tacky or looks shiny from product, you probably applied too much, which often leads to dryness and that tight, uncomfortable feeling.
Give it a clear lane in your routine. On exfoliant nights, keep your routine boring: gentle cleanser, exfoliant, moisturizer. Skip extra “active” steps like strong vitamin C, additional acids, and harsh masks on the same night. When I am busy, I like to apply BHA right after cleansing, wait a minute or two while I tidy up the bathroom counter, then seal it in with moisturizer.
Protect the barrier so pores look smaller. Over-exfoliation can make pores look more obvious because irritated skin reflects light unevenly and dehydrates easily. If you start seeing flaking around your nose or makeup clinging to dry patches, swap a few exfoliant nights for recovery nights and add a simple, fragrance-free moisturizer. And if you are using any exfoliant consistently, daily sunscreen is non-negotiable for keeping texture and discoloration from creeping in.

Frequently Asked Questions ▾
Is BHA or AHA better for clogged pores?
For true clogged pores, BHA is usually the better first pick because it is oil-soluble, so it can move into the pore lining and help loosen the mix of oil and dead skin that creates congestion. AHAs (like glycolic or lactic) are great for surface texture and dullness, but they do not target pore congestion as directly. If you have both rough texture and clogs, an AHA and BHA blend can be effective, but it is easier to irritate your skin if you start too fast.
How often should I use a chemical exfoliant for clogged pores?
Most people do best starting slowly, like 2 to 3 nights per week, then increasing only if your skin stays calm and hydrated. If you jump to daily use too soon, you can end up with dryness and more visible pores from irritation. Watch for stinging with basic moisturizer, tightness by midday, or flaking around the nose and mouth, those are signs to back off. Consistency beats intensity, especially with pore congestion that built up over months.
Can a chemical exfoliant cause purging, and how do I tell?
Yes, especially with BHAs, you may see a short-term “purge” as clogs come to the surface more quickly. Purging typically shows up in your usual breakout areas and improves within about 4 to 6 weeks of steady use. If you are getting painful inflamed breakouts in new areas, or irritation that keeps worsening, that is more likely a reaction, not purging. When in doubt, pause for a week, simplify your routine, and reintroduce more slowly.
Can I use salicylic acid and retinol in the same routine?
You can, but most skin types tolerate them better on alternating nights, especially at the start. Using both on the same night raises the chance of peeling, sensitivity, and a compromised barrier, which can make pores look worse for a while. A practical schedule is BHA 2 to 3 nights per week, retinol 2 nights per week, and the rest as recovery nights with just cleanser and moisturizer. If you do combine them, keep everything else very gentle and be diligent with sunscreen.
