1. MASKS. If you're going to go for a mask, go deep: Mario Badescu Temporary Lifting Mask, $35, revives tired-looking skin, while Dr. Sebagh Deep Exfoliating Masque, $115, rivals an in-office peel. One or the other once a week gets pricey, but they're worth it.
2. PRESCRIPTION VITAMIN A CREAMS. You never want to scrimp when it comes to diminishing sun damage, wrinkles, and zits. To spring for: Rx-strength salves like Avita (starts at $50), Tazorac (starts at around $110), or Retin-A Micro (starts at around $120).
