You can fight fine lines and wrinkles all day long, but uneven skin tone is actually the number one indicator of age. And unless you’ve successfully shunned the sun your entire life, dark spots will eventually be a concern. On the bright side, we have a ton of complexion-perfecting products for you! Whether you have a collection of brown spots invading your forehead or you’re just looking to get in front of the issue, there’s a skin-brightening solution for you. Vitamin C is an antioxidant with numerous anti-aging benefits. It boosts collagen and elastin production, while inhibiting tryosinase, an enzyme involved in melanin production. Vitamin C is well tolerated in most people, but the one drawback is that, like all antioxidants, it’s highly unstable. Meaning, it loses effectiveness when exposed to light, heat, and air. So store your products in a cool, dry place, and pick ones that have a pump delivery system (like the Advanced Active Radiance Serum from Murad) opposed to squeeze tube, which allows air to creep in.
