Schedule a full-body skin-cancer scan. Any time of the year is fine, as long as you have a yearly checkup with a dermatologist, says Kling. If you've had skin cancer in the past, schedule a six-month follow-up in August. Always be on the lookout for moles that change color, size, or shape.

Start treatments like retin-A. Winter is the best time, says Kling, since you're not spending as much time outdoors in the sun.

Be your own valentine. Flowers are always nice to receive from a loved one, but it's no fun waiting for the doorbell to ring. On February 14, give yourself a rose-infused bath with Aromafloria Rose Bath Salts ($10, www.aromafloria.com).
