Ultimately, your skin should be soft and smooth, free of bumps, and flakiness. However, texture can become uneven with time. As we age our skin cell turnover slows and dead cells start to build up on the surface, leading to irregularities and dullness. Many textural problems can be solved (or slowed) by staying internally hydrated, with proper cleansing of skin, toning and moisturizing along with occassional non-abrasive, non-acidic, enzyme based exfoliation. The idea is not to shock or traumatize your skin in any way.
