Amlactin: The Derm-Approved Lotion That Does Way More Than You Think
If you've ever Googled “Amlactin for crepey skin,” you’re not alone. It’s one of the most searched body lotions for a reason — and yes, as a board-certified dermatologist, I absolutely recommend it for smoothing fine, wrinkly texture.
But here’s the thing: Amlactin isn’t just a one-trick lotion. Thanks to its superstar ingredient, lactic acid, it quietly solves a whole range of common (and frustrating) skin concerns. From keratosis pilaris to bumpy arms, ingrown hairs, and rough heels, it deserves way more hype than it gets.
In today’s post, I’m walking you through all the ways I use (and recommend) Amlactin — including how to apply it for best results, who should skip it, and how it compares to other exfoliating body products.
What Is Amlactin, Anyway?
Amlactin is a dermatologist-loved body lotion formulated with lactic acid, a type of alpha hydroxy acid (AHA) that gently exfoliates and hydrates at the same time. Think of it like a chemical exfoliant and moisturizer in one.
Unlike gritty scrubs, lactic acid works below the surface — loosening dead skin cells, improving texture, and drawing moisture in. That’s what makes Amlactin so effective for:
Crepey skin
Keratosis pilaris (KP)
Rough, bumpy arms and thighs
Post-shave ingrowns
Dry, scaly legs
Callused feet and elbows
All the Ways I Use Amlactin
1. Crepey Skin on Arms, Legs, and Chest
This is probably what Amlactin is best known for. I recommend it often for my patients with thinning, wrinkled skin — especially on the arms and chest. It helps smooth and plump the appearance over time.
Pro tip: Apply daily after a lukewarm shower, ideally within 3 minutes of toweling off.
2. Keratosis Pilaris (“Chicken Skin”)
If you have rough, bumpy patches on the backs of your arms or thighs, you’re likely dealing with KP. Amlactin gently exfoliates the plugs that clog your hair follicles without irritating the surrounding skin.
Pro tip: Pair with a gentle cleanser (like Vanicream or CeraVe SA) and avoid aggressive scrubbing.
3. Post-Shave Ingrown Hair Prevention
Exfoliation is key to keeping hair follicles clear and preventing painful ingrowns. Amlactin can help keep bikini lines, underarms, and legs smoother and bump-free — just don’t apply it immediately after shaving, or it’ll sting.
Pro tip: Wait at least 12–24 hours after shaving.
4. Dry, Flaky Legs That Never Seem Smooth
If you feel like no amount of lotion gets rid of that scaly look, lactic acid is your secret weapon. Amlactin helps skin retain moisture better by exfoliating the dead layer blocking it.
5. Callused Feet and Rough Elbows
I love using Amlactin at night on thick, dry areas like heels and elbows. Slather it on, then throw on socks before bed — you’ll wake up with noticeably softer feet.
Who Should Skip It?
Amlactin isn’t for everyone. If you have open cuts, broken skin, eczema flares, or recently shaved areas, it can sting. I also don’t recommend using it on your face — it’s a body product for a reason.

Final Derm Thoughts
Amlactin is one of those unsexy, under-$20 products I end up recommending again and again. It’s simple, backed by science, and works incredibly well if used consistently. Whether you're tackling crepey skin, KP, or just want smoother legs — it deserves a permanent spot on your shower shelf.
If you’re using it and not seeing results, let’s troubleshoot — sometimes it's as simple as how you’re applying it. And if you haven’t tried it yet? Consider this your derm-signed permission slip.
