Can Dark Window Tint Help Lessen Sun Exposure and Help Manage Melasma?

Question

I have the darkest window tint on the market on my car windows, partly because I have Melasma over my entire face and want to lessen sun exposure while driving. Of course I use 30spf sunblock everyday but I live in sunny California and spend lots of time in the car. Does the dark window tint help, or am I fooling myself? The police don't like dark window tint but I feel it's a "medical" necessity.

Window films are rated by light transmission, heat prevention, and UV blocking abilities. UV rating is the most important for you (melasma) and there are films that block >99% of UV rays that are almost clear.  Ultraviolet light has 2 major classifications of wavelengths: Ultraviolet A and B. UV B causes burns basal cell and squamous skin cancer and is blocked by glass. However UV A passed through and causes tanning, premature aging/wrinkling and age spots of the skin and increases the risk of developing Melanoma. Bottom line: use sunscreen whether windows or not. Generally a SPF over 30 is recommended. There are several powder sunscreens that work well. #wrinkleprevention#sunscreen

Melasma is a very stubborn condition. It is impacted by heredity, hormones, and sunlight. Even infrared (heat like from ovens) energy can worsen some patients. The key is a combination approach: no extra estogen if possible, no sun by using SPF and hats, and the tint is a great idea, and even topical antioxidants may help with the hydroquinone, retinoids and other skin bleachers.
