Kojic Acid for Keratosis Pilaris: What to Know

Keratosis pilaris commonly feels rough on the upper arms, thighs, or cheeks. The bumps may be skin-coloured, red, or surrounded by darker marks after irritation. Scratching, picking, close shaving, or aggressive exfoliation can prolong inflammation. Similar bumps can also be [Ingrown Hairs](/symptoms/ingrown-hairs/) or other [Skin Bumps](/symptoms/skin-bumps/), so appearance alone is not always enough to identify them.

If a clinician has confirmed keratosis pilaris, use a gentle cleanser and regular moisturiser, avoiding rough scrubs and picking. Treatments such as [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) may soften roughness; [Topical Retinoids](/treatments/medical-dermatology/topical-retinoids/) may be considered for some people under medical guidance. Kojic acid should be reserved for intact skin and tested carefully, because irritation can deepen marks. A dermatologist may discuss a [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/) or other option when appropriate; [Laser Hair Removal](/treatments/laser-and-energy/laser-hair-removal/) is not a general treatment for keratosis pilaris.

Seek review if bumps are painful, pus-filled, rapidly changing, very itchy, or limited to an unusual area. Arrange care when a product causes persistent burning, swelling, or blistering, or when the diagnosis is uncertain. A clinician can distinguish keratosis pilaris from folliculitis, eczema, or ingrown hairs and match treatment to the cause.

Are these bumps keratosis pilaris or another follicular problem? Is the colour change post-inflammatory pigmentation? Which moisturiser or prescription option fits my skin? Should I avoid kojic acid while the bumps are inflamed?
