Everything I just wrote is fact. You don't know what you're talking about that. If you use more than sun factor 8 ->, then you won't get any vitamin D at all. I'm sure you know a lot about doing the dishes and doing your nails, but the stuff I just stated is a
fact. I'll explain it to you in detail if you think you'd understand. I got the same skin as my father, so I'm gonna look even better the older I get.

You are SO full of it (and yourself

) Who is your source?? Tanning beds r us???
Here, from the NIH (national institute of health) one of MANY places you can find this info on vitamin D... I will provide the link too:
approximately 5-30 minutes of sun exposure between 10 AM and 3 PM at least twice a week to the face, arms, legs, or back without sunscreen usually lead to sufficient vitamin D synthesis and that the moderate use of commercial tanning beds that emit 2%-6% UVB radiation is also effective [10,33]. Individuals with limited sun exposure need to include good sources of vitamin D in their diet or take a supplement.
Despite the importance of the sun to vitamin D synthesis, it is prudent to limit exposure of skin to sunlight [36] and UV radiation from tanning beds [37]. UV radiation is a carcinogen responsible for most of the estimated 1.5 million skin cancers and the 8,000 deaths due to metastatic melanoma that occur annually in the United States [36]. Lifetime cumulative UV damage to skin is also largely responsible for some age-associated dryness and other cosmetic changes. It is not known whether a desirable level of regular sun exposure exists that imposes no (or minimal) risk of skin cancer over time. The American Academy of Dermatology advises that photoprotective measures be taken, including the use of sunscreen, whenever one is exposed to the sun [38].
