In my over 60 years of experience, I've learned four things.
1. Don't sunbathe or use a solarium. I've had skin cancers removed from my nose. Not a pretty sight. A moderate amount of sun is healthy and necessary. Tanning also ages/wrinkles your skin making it the consistency of leather.
2. Never put anything on your skin that could make you sick if you swallow it. I use only skin creams with 100% natural ingredients. My cream of choice is Weleda, but I don't know if I'm allowed to say that. Hope so.
3. Eat healthy food and watch out for the gunk. You will have a beautiful healthy glow as your skin is able to get enough oxygen.
4. Get enough exercise. Sitting around is not what our bodies were created to do.
I have one last suggestion: Check out the ingredients in your makeup. Some of it is toxic. Natural is always the best path to follow.
