I think part of the secret to a protective tan is length of exposure time each day. A fair skin friend of mine tans very well for over 35 years because she does it slowly each year. No moles, lesions, psoriasis, basal cell carcinomas, melanomas have ever occurred. Interestingly, nudists/naturists have lower cancer rates than non-nudists.
Humans need protective sunshine for at least strong bones. And the psychological benefits are well known. See for example Dr. Aileen Goodson’s text, ‘Therapy, Nudity & Joy, Elysium Press, 1991.
