We have some good news and some bad news: that firm, even skin of our 20s won’t necessarily last forever. But today, the wealth of anti-aging products can keep our skin healthy and glowing well into middle age. So where – and more importantly when – do we begin when it comes to anti-aging? According to Annie Chiu, MD, Celebrity Dermatologist, “Anti-aging is all about prevention. Starting early is incredibly important. When we have dewy collagen and fabulous skin in our 20s, it’s easy to take that for granted. But it’s all about preventing collagen loss, uneven pigmentation, wrinkles and sagging over time.” It’s important to know exactly what your skin needs, so we’ve chosen our favorite anti-aging products for every age.
