BioLogical lotion helps to keep your skin hydrated. Minimizing your exposure to climates with low humidity, harsh winds, dry heat, high altitudes and sun can also prevent loss of natural oils in the skin. A healthy diet also plays a role to strengthen the skin’s ability for maintaining moisture. Foods rich in the essential fatty acids help skin cells stay hydrated. It is a combination of diet, ingredients found in BioLogical and sleep that all help skin stay healthy.
