No doubt it’s effective, but what do you think about its safety ? I always wonder would it help protect you against skin cancer , or make you more susceptible to it , I use it at 250mcgs twice weekly and use tanning bed maybe once every 10 days or even 2 weeks , my coworkers say I don’t look like a white person anymore lol , a while ago I use to tan twice a week and my lips started to turn purple , like ok time to back away from that tanning bed a little bit lol , but I never get any side effects that some talk about from it , except really dark skin , love to hear some opinions on this
