The proven benefits of daily sunscreen use

A recent study looked at what happened when women applied sunscreen for 3 out of 4 days instead of daily. Those who didn't apply sunscreen everyday had skin changes that were visible under a microscope - changes that over time translated into fine lines, brown spots and uneven skin tone. Keep in mind itís much easier to prevent sun-damage to skin than to manage premature aging caused by UV exposure. If pigmentary changes are already a reality, look for formulations with skin-lightening capabilities. Some common depigmenting ingredients include ascorbic acid (vitamin C), N-acetyl glucosamine (NAG), and hydroquinone. Ascorbic acid is a naturally occurring antioxidant found in citrus fruits and leafy green vegetables; NAG is a stable from of glucosamine that interrupts the chemical signals and inhibits melanin production; and hydroquinone has been one of the most common lightening agents, but its use has been questioned due to the risk for permanent depigmentation and other potentially serious side-effects, especially at higher concentrations. If youíre considering using a skin-lightening product, make certain to apply a broad spectrum sunscreen daily.
