I’m impressed—and you sound like you’re on the right track. Even if none of your products are explicitly labeled “Anti-Aging Cream For People Who Don’t Want To Look Old”, I’m sure they’re infused with antioxidants, vitamins, proteins, and other ingredients that are healthy-skin staples. And, honestly, the most important thing you’re doing is setting up a consistent routine. That’s the hardest part and what most people dilly-dally over. “But it’s so much… work!” people mutter or they’ll dejectedly ask “What’s the point?”: I’ve said it once, I’ll say it again. So much of skincare is being consistent. Skin, like a potted plant, needs to be fed and watered regularly. Anyway, I’ll get off my soapbox to answer your questions: a) I personally don’t use a neckcream. But I do make sure to put SPF on it every single day (and ditto for the backs of my hands (and face, obviously)). b) don’t ever smoke. c) add a retinoid to your daily routine. It’s the only ingredient that every single one of the many dermatologists I’ve ever met agree on and like an insurance policy for your skin—you won’t have immediate results (but when you’re 35 you’ll be very glad you’ve been using one). Keep up the good work!
