Medical Skin Aesthetics can't emphasize enough the importance of using both UVB and UVA sunblock protection daily on the full body and face. With repeated sun exposure without protection can cause extreme sun damage that includes wrinkles, brown spots and the risk of skin cancer. Our medical skin clinic carries true broad-spectrum UVA/UVB sunblocks for everyday wear. Sunblock should be worn regardless if not in direct sun and reapplied every thirty minutes if in direct sun. Please don't forget to reapply after swimming as there are no true waterproof sunblocks.
