To look great by tomorrow:
Get a lactic or salicylic acid peel

Without exfoliating regularly, dead skin cells will begin to pile up, which causes an increase in fine lines and dullness. Beverly Hills, California-based aesthetician Gina Mari says that for a temporary reduction in fine lines and a boost in skin color, all you need is a quick peel. The lactic and salicylic acids provide a light exfoliation that not only removes the dead skin, but encourages new skin cells to turn over, so that, according to Mari, “new fat, healthy cells are encouraged to come to the surface of your epidermis” to create a youthful glow.

Or, if you have a special date coming up (like your wedding or high school reunion), get an instant glow and firmness to your skin with oxygen therapy. When your skin is extremely dehydrated, it looks dry, flaky and can’t absorb moisture. According to Mari, the combination of oxygen therapy and antioxidants will give you glowing skin that you’ll notice immediately. The oxygen helps push the antioxidants, like vitamins A, C, and E, deep into your pores, allowing your skin to reap their full benefits. You’ll walk away with “glowing skin, a plumpness that will last for about three days, and a reduction in the appearance of fine lines and wrinkles,” says Mari.
