This next one we are told from the day we are born but still somehow always manage to “forget”. Protect your skin! The sun is responsible for 90% of how our skin ages so mae sure to wear SPF every time you go outside. Look for facial SPF that is at least 30 and a UVA rating of four stars or higher. UVB rays are what burns the skin which is what the SPF will protect against and UVA will protect the skin from UVA rays that destroy collagen.
