For most people, the twenties are a busy and active time, full of days in the sun and plenty of exposure to the elements. Though aging may not yet be a concern for most, there are steps that can be taken to prevent premature aging. Of course, including a daily moisturizer with SPF is key in preventing the damage that UV rays can cause. The skin of someone in their twenties tends to be on the oilier side, leaning towards an oilier t-zone and hairline—especially the nose. For most twenty-somethings, there is no problem with firmness or elasticity, but those with significant sun exposure may already be seeing uneven pigmentation, freckling, and fine lines.
