What are the bumps on your legs?

Keratosis pilaris, often shortened to KP, causes small, rough bumps around hair follicles, commonly on the thighs. Keratin, a protein found in skin, hair and nails, builds up and plugs the follicle openings. The bumps can be skin colored, red, white or brown. KP is harmless and does not need treatment unless its appearance, dryness or itching bothers you.234

Which cream should you choose?

Cream typeWhat it can help withHow to choose
Plain moisturizing cream or ointmentDryness that makes bumps more noticeableA starting point when dryness is the main problem
Urea creamSoftening dry skin and smoothing rough bumpsAn option when you want moisturizing and exfoliating care
Lactic acid or ammonium lactate creamGradually smoothing the skin surfaceAn option for persistent rough texture
Salicylic acid creamReducing the buildup responsible for rough bumpsAnother exfoliating option; follow its directions carefully

A thicker cream or ointment moisturizes better than a lotion, so the lighter bottle does not win by being easier to pour. Choose a fragrance free moisturizer for daily care. Exfoliating creams contain ingredients called keratolytics, which help remove excess dead skin cells. They are generally preferable to vigorous physical scrubbing, but they can still irritate skin if used too often.12

AmLactin and CeraVe SA cream are examples used for rough, bumpy skin. Neither name makes a product the right choice for every person. The practical choice is a moisturizer you can use regularly, with an exfoliating ingredient if your skin tolerates it. There is no single treatment that reliably clears KP for everyone.35

How to apply cream to your legs

  1. 1Wash with warm rather than hot water and a mild cleanser. Keep showers short and avoid scrubbing the bumps.
  2. 2Apply your exfoliating product exactly as its directions describe. More product or more frequent application can leave skin raw and irritated.
  3. 3Apply moisturizer afterwards. For moisturizing after bathing, apply to damp skin within five minutes.
  4. 4Reapply moisturizer when your legs feel dry. Moisturizing two or three times daily can help manage dryness.

For exfoliation, start two or three times weekly, then increase gradually if needed and tolerated, without exceeding the product directions. Daily moisturizing and daily exfoliation are not the same instruction. If an exfoliating cream leaves your legs too dry or irritated, stop it for a few days rather than applying another layer.16

What results can you expect?

Moisturizing softens the bumps and reduces dryness; exfoliating ingredients gradually smooth the surface. Exfoliants do not relieve the redness or itching associated with KP, so smoother texture does not necessarily mean that every visible mark disappears. Expect weeks of consistent treatment before a noticeable improvement, not rapid clearance.13

KP has no cure, and maintenance often involves treating the skin a few times weekly once it is clearer. Many people notice improvement with age or during summer, then more visible bumps in dry winter weather. Moisturizing remains useful because dry skin makes KP more noticeable.36

What else helps on legs?

  • Avoid picking or scratching the bumps, which can cause infection or scarring.
  • Avoid tight, thick or abrasive clothing that rubs the affected areas.
  • Rethink shaving or waxing if either makes the bumps worse; both can trigger more bumps.
  • Use a humidifier when the air is dry.

Self tanner tends to make bumps more obvious rather than hide them, which is a curious approach to camouflage.6

When should you stop or get the bumps checked?

Reduce exfoliation if you develop worsening dryness, redness, rash or irritation. Painful, larger or pus filled bumps, especially ones that appear suddenly after shaving, need assessment rather than an assumption that they are KP. Very itchy, red, dry patches can also have another cause. A clinician can usually identify KP by examining the skin; see a dermatologist if home treatment does not help.136

What cream helps keratosis pilaris on the arms?

The same moisturizing and exfoliating options apply to the upper arms, another common location for KP. Urea, lactic acid, ammonium lactate and salicylic acid are options for rough bumps there. Apply moisturizer after showering while the skin is still damp, and avoid vigorous scrubbing.13

What cream can you use for keratosis pilaris on the face?

KP can occur on the cheeks, particularly in children. Moisturizers and treatments that soften follicular scale are options, but acid creams should be avoided in young children because they can burn and sting. Facial bumps with eyebrow hair loss or small scar like depressions need assessment: a rare facial form of KP causes permanent hair loss. That is different from ordinary rough bumps on the legs.457

Are there prescription creams for keratosis pilaris?

Yes. If moisturizing and gentle exfoliation are not enough, a clinician can consider stronger acid treatments or topical retinoids, medicines applied to the skin that reduce keratin buildup. Options include tretinoin, adapalene and tazarotene. Clinical treatment strengths include tretinoin 0.1%, adapalene 0.1% and tazarotene 0.05%; these are treatment options to discuss, not a reason to start with the strongest cream.235

Topical steroids can help redness or itching, but they are not a continuing maintenance cream for KP. Unless a clinician directs otherwise, use them only once or twice daily for no more than one to two weeks.1

What keratosis pilaris cream works for sensitive skin?

A plain fragrance free cream or ointment is a sensible starting point when irritation is a concern. It addresses dryness without adding an exfoliating treatment. Urea creams also soften dry skin, but no exfoliating ingredient is irritation proof. Avoid harsh brushes and pumice stones, and pause an active cream if skin becomes irritated. For a young child, avoid acid creams and discuss treatment with a clinician.256
