What this hub covers
Exfoliants in this library are leave-on acids: salicylic acid for oil-soluble pore work, and glycolic, lactic, and mandelic acids for surface renewal. They are not scrubs. The payoff is smoother texture and clearer congestion; the cost is barrier stress if you use them too often or next to a retinoid the same night.
Water-soluble AHAs and oil-soluble BHA do different jobs. Picking “an acid” without that distinction is how people end up over-exfoliated and then blame every other product in the routine.
Sunscreen the next day is non-negotiable after chemical exfoliation. If you will not wear it, this is the wrong category to lean on.
Cosmetic reference only — not medical advice. Persistent irritation, swelling, or symptoms that worry you deserve a clinician, not another serum.
How to use this list
- Match BHA to congestion-prone oily skin and AHAs to surface texture or dullness — then check each page’s caution list.
- Do not run two leave-on exfoliants in the same evening unless a dermatologist has told you to.
- Open the pairing pages that involve retinol plus an acid before you invent a “skin cycling” schedule from social media.
Ingredients in this category
4 library entries tagged exfoliant.
Exfoliant
Salicylic Acid
An oil-soluble exfoliant that gets inside pores. The standard choice for blackheads and congestion, and easy to overdo.
Exfoliant
Glycolic Acid
The smallest AHA, so the most penetrating and the most irritating. Strong results on texture and tone if your skin can take it.
Exfoliant
Lactic Acid
A larger, gentler AHA that exfoliates and hydrates at the same time. The sensible first acid for dry or nervous skin.
Exfoliant
Mandelic Acid
The largest common AHA and the gentlest. A good option for sensitive skin and for deeper skin tones prone to post-inflammatory marks.
