Since your goal is smoother skin, glycolic acid gives you a second exfoliating option. It's a small alpha-hydroxy acid from sugar cane that helps lift away the dead cells clogging the follicles.
Glycolic acid is a plant-derived AHA often chosen for unclogging plugged follicles and refining rough texture. Its small molecule size lets it work on the surface layer quickly.
Dose or use Apply a glycolic-acid lotion, pad, or cream to the bumpy areas once daily or every other day. Introduce it slowly to see how your skin responds.

Caution: May sting or redden sensitive skin and increases sun sensitivity, so wear sunscreen. Avoid layering it with retinol on the same night unless your skin tolerates both, and keep it off broken skin.
An AHA that dissolves the keratin plugs behind the bumps
Why it may be relevant
You want the rough bumps gone. Lactic acid is an alpha-hydroxy acid that gently loosens the built-up keratin plugging each follicle, so the skin feels smoother over time.
Alpha-hydroxy acids like lactic acid are one of the most widely used at-home approaches for the bumpy skin of keratosis pilaris. It also draws in moisture, so it exfoliates without over-drying.
Dose or use Apply a lactic-acid lotion or cream (often around 10-12%) to the affected areas once daily, usually after bathing. Start every other day if your skin stings.

Caution: Can cause tingling, stinging, or irritation, especially on broken or freshly shaved skin. AHAs increase sun sensitivity, so use sunscreen. Keep it away from the eye area.
A beta-hydroxy acid that dissolves the keratin plugs inside each follicle
Why it may be relevant
You want the rough bumps smoothed. Salicylic acid is an oil-soluble BHA that gets into the follicle and loosens the keratin plug behind each bump, so the skin gradually feels less sandpapery.
Salicylic acid is one of the most commonly recommended keratolytics for keratosis pilaris and shows up across dermatology reviews as an effective, well-tolerated topical for refining the bumpy texture. Because it is oil-soluble, it complements water-soluble AHAs like lactic and glycolic acid.
Dose or use Apply a salicylic-acid lotion or wash (commonly around 2%) to the affected areas once daily, usually after bathing. Start every other day if your skin feels tight or stings, and follow with moisturizer.
Key study Systematic Review (2022, PMID 32886029): Treatment of keratosis pilaris and its variants: a systematic review — identified salicylic acid among the topical treatments that improved keratosis pilaris lesions, alongside other keratolytics, though most included studies were small.

Caution: Can cause dryness, stinging, or peeling, especially on sensitive, freshly shaved, or broken skin. Exfoliated skin is more sun-sensitive, so use sunscreen. Avoid applying to large body areas during pregnancy without checking with your doctor first.

Emollient oil that softens dry, rough, bumpy skin
Why it may be relevant
You want to soften the dry, flaky skin. Coconut oil is a rich emollient that seals in moisture, making the bumps feel less rough between exfoliating.
The library documents coconut oil for dry-skin conditions like eczema and psoriasis. Because keratosis pilaris looks and feels worse on dry skin, keeping the area moisturized helps soften the plugs.
Dose or use Massage a thin layer of virgin coconut oil into the affected areas after bathing, while skin is still damp, once or twice daily.
Key study Traditionally used as an emollient for dry, rough skin; its use for keratosis pilaris specifically has not been confirmed here by a controlled clinical trial.
EvidenceCenturies of traditional use · Human evidence not yet assessedTime to resultsSkin usually feels softer within days; the bumpy texture eases more gradually.Traditional useLong-standing traditional staple
Caution: Can clog pores for some people and may trigger breakouts on acne-prone areas like the face. Do a small patch test first if your skin is sensitive.

Rich butter that deeply hydrates flaky, rough skin
Why it may be relevant
If you prefer a thicker balm to an oil, shea butter is a rich emollient that hydrates and softens the dry, flaky skin that makes keratosis pilaris feel rough.
Shea butter is a long-used natural emollient for dry, keratinized skin. Keeping the area well moisturized softens the bumps and eases the sandpapery feel.
Dose or use Warm a small amount between your fingers and massage into the affected areas after showering, once or twice daily.
Key study Traditionally used as a rich emollient for dry, rough skin; this specific use for keratosis pilaris has not been confirmed here by a controlled clinical trial.

Caution: Generally well tolerated, but patch test first if you have a tree-nut allergy or very acne-prone skin, as heavy butters can occasionally clog pores.

Mechanical exfoliation that smooths bumpy skin over time
Why it may be relevant
If you'd rather smooth the bumps physically than with acids, dry brushing sweeps away the dead surface cells that build up around the follicles.
The library entry names keratosis pilaris (bumpy skin) directly, noting it smooths texture over time. It's a low-cost, drug-free way to keep the rough patches buffed down.
Dose or use Using a firm natural-bristle brush on dry skin, sweep gently over the bumpy areas in short strokes before bathing, a few times a week. Follow with moisturizer.
Key study Listed in the library as a traditional use for keratosis pilaris (bumpy skin, smooths texture over time); not confirmed here by a controlled clinical trial.

Caution: Brush lightly; too much pressure can scratch or inflame the skin and worsen the bumps. Avoid on broken, sunburned, or actively irritated skin.

Vitamin A topical that normalizes skin cell turnover
Why it may be relevant
You want to smooth the bumps at the source. Topical retinol encourages skin cells to turn over and keeps follicles from getting plugged, which is what forms the rough bumps.
The library entry lists improving skin smoothness and texture among retinol's effective uses, and normalizing keratinization is a standard way to address the follicular plugging behind keratosis pilaris.
Dose or use Apply a pea-sized amount of a low-strength retinol to affected areas at night, 2-3 times a week to start, building up as tolerated. Moisturize afterward.
Key study Library copy documents retinol as effective for skin smoothness and texture; this specific use for keratosis pilaris has not been confirmed here by a controlled clinical trial.
EvidenceCenturies of traditional use · Human evidence not yet assessedTime to resultsRetinol works gradually; expect 8-12 weeks before texture visibly changes.Traditional useLong-standing traditional staple
Caution: Commonly causes dryness, flaking, and irritation early on, and increases sun sensitivity, so use sunscreen. Not recommended during pregnancy or breastfeeding.

Low vitamin A can cause rough, thickened, bumpy skin
Why it may be relevant
You're looking at the inside-out angle. Low vitamin A is a classic driver of rough, thickened, bumpy skin, so it's worth making sure your intake is adequate.
The library entry lists thickened, dry, or rough skin (hyperkeratosis) as a sign of vitamin A deficiency, which closely mirrors the follicular bumps of keratosis pilaris. Vitamin A also supports normal skin cell turnover.
Dose or use Focus on vitamin A-rich foods like liver, eggs, and dairy, plus beta-carotene sources such as carrots, sweet potato, and spinach. Ask a clinician before taking high-dose supplements.
Key study Vitamin A deficiency is a well-recognized cause of follicular hyperkeratosis; keratosis pilaris is not caused by deficiency alone, and correcting intake has not been confirmed here as a treatment for it.
EvidenceCenturies of traditional use · Human evidence not yet assessedTime to resultsSkin changes from correcting a true deficiency unfold over weeks to months.Traditional useLong-standing traditional staple
Caution: Vitamin A is fat-soluble and builds up in the body; high-dose supplements can be toxic and are unsafe in pregnancy. Don't self-prescribe large doses, and get levels checked first.
