Skin Tip of the Day: RASPBERRIES! Eat them. Lots of them. Raspberries have very high amounts of antioxidants, which slow down the aging of your skin. They also contain anthocyanins, which are nutrients that give raspberries their beautiful color, and can give you the same beautiful complexion too, as well as tighten your skin! And last but not least, the seeds of raspberries contain high levels of Omega-3 and Omega-6 fatty acids which are great for treating eczema and psoriasis.
