Glow Definition
In skincare, a keratolytic is an ingredient that helps loosen and remove built-up dead skin cells from the surface, often by softening the outermost layer so it can naturally shed. These exfoliating agents work beneath the surface to support smoother texture and clearer-looking skin by encouraging regular skin cell turnover.
Most keratolytic ingredients are considered a type of chemical exfoliant, with salicylic acid being one of the most recognized for oily or congestion-prone skin. While not always labeled as such, keratolytics play a behind-the-scenes role in many formulas that gently resurface or refine the skin over time.

Why It Matters
Keratolytic ingredients don’t just exfoliate — they dissolve the glue that holds excess dead skin cells together. This behind-the-scenes action can help prevent buildup that contributes to dull texture, congestion, or uneven skin tone. While they’re often found in formulas labeled as chemical exfoliants, the distinction matters — not all exfoliants are keratolytic, but most keratolytics play a long-game role in maintaining smoother skin over time.
Their value comes down to consistency. When used appropriately, keratolytic actives like salicylic acid or urea can support gentle skin cell turnover without the need for aggressive scrubbing — making them especially useful for those navigating clogged pores, keratosis pilaris, or over-exfoliation recovery. As with all exfoliating steps, balance is key.
GLOW TIP When incorporating keratolytic ingredients into your routine, think of them as slow-and-steady refiners — pair with a barrier-repair moisturizer to buffer any dryness and maintain glow without overdoing it.
Why We Love It For Glow
Keratolytics support the skin’s natural renewal rhythm by encouraging dull, compacted surface cells to shed — creating space for light to reflect more evenly across the skin. This smoothing effect can subtly enhance radiance, especially when used as part of a well-paced exfoliation routine.
What sets keratolytics apart isn’t just their surface-deep effect, but their role in making everything else in your routine feel more efficient. When used thoughtfully (not excessively), they can help serums and moisturizers absorb more seamlessly — a quiet boost that elevates your overall glow strategy.

FAQ
What is a keratolytic cleanser, and who should use it?
A keratolytic cleanser is a face wash that includes ingredients like AHAs (e.g., glycolic or lactic acid) or BHAs (like salicylic acid), designed to help dissolve the bonds between dead skin cells for a smoother feel. These cleansers may appeal to those with oily skin, clogged pores, or a desire to gently refine surface texture within their routine.
Is salicylic acid considered a keratolytic ingredient?
Yes — salicylic acid is a beta hydroxy acid (BHA) that acts as a keratolytic, making it a common choice in cleansers, toners, and targeted exfoliants. Its oil-soluble properties allow it to work on the surface of the skin as well as inside pores, helping to clear buildup.
Can I use a keratolytic product every day?
It depends on the concentration and the product type. Some gentle keratolytic formulas, like certain cleansers or toners, may be used daily, while stronger treatments are better reserved for 2–3 times a week. Always pair with barrier support and SPF, especially when incorporating acids into your routine.
