Protect the Skin on Your Neck and Chest
Put the same sunscreen on your neck and chest that you do on your face.
This may sound obvious, but it’s surprising how many of us don’t do it regularly. And it looks odd to have facial skin that looks pretty good, with skin on the neck and chest that is red, blotchy, leathery, or sun damaged.
Your neck especially has few oil glands, so apply a moisturizer there under your sunscreen. Same with your chest. If your Vitamin A, retinoid, or antioxidant repair creams irritate your neck or chest, try them every other night, or twice a week, or dilute them with your moisturizer.
If your neck and chest need a lot of repair from sun damage, you may want to consider laser treatments. The Photorejuvenation/IPL is best for brown spots, redness, and blotchiness.
