Uneven skin texture is usually caused by an excess of dead skin cells that have built up on the surface of the skin. This can make your skin feel rough or bumpy to the touch while also giving your skin a dull appearance. Uneven skin texture can also be a result of dehydration and aging. As skin ages, dead skin cells build up and make your skin rougher and coarser. Uneven skin texture leaves skin looking older and duller because it doesn’t reflect light as well. SF Bay Cosmetic Surgery Medical Group offers patients non-invasive treatments that can help improve the texture and tone of your skin.
