Keratosis Pilaris
Keratosis Pilaris (KP) is commonly seen and felt as rough, tiny red spots on the back of the arms. Clinically, these rough, red spots are plugged up follicles with keratotic spines. In some cases these spots are also seen on the cheeks/eyebrow areas, buttocks, back, and thighs. Rarely,KP is associated with eyebrow hair-loss and scarring. Very commonly, keratosis pilaris is associated with atopic dermatitis or icthyosis vulgaris.
The treatment of keratosis pilaris is symptomatic as no cure is known. Very reasonable clearing treatment may be achieved with Lactic acid products such as Lac-Hydrin® or AmLactin®. These products are used twice a day and may be expected to soften the skin and get rid of the hard keratotic plugs. Also, salicylic acid, glycolic acid, prescription retinoids, and urea products may be used.
Here's how to apply medications used for KP:
Retin-A/tretinoin: apply a thin layer to the affected area on the face 1-2x/day, or on the body 2x/day; watch for over-drying
Lac-Hydrin/AmLactin: apply the lotion to the affected area 2-3x/day
Carmol/urea: apply the cream to the affected area 2-3x/day
Salex/salacylic acid: apply the lotion 2-3x/day; watch for over-drying
If you stop any of these treatments, the KP will return as it is a genetic condition. Usually, it will improve as you get older.
