Ive had botox in the forehead 3 weeks ago, can I go under a sunbed?

What do you want, melanoma?  I don't care what BS the sunbed people give you about how much healthier their machines are than tanning in the sun.  These beds irradiated you with high levels of ultraviolet light.  These wavelengths cause skin cancer.  Will a little sun inactivate your BOTOX: no.  Should you go out and tan in the sun-no not really.  If you need a golden glow, get a spray tan.  These do not cause cancer.  Are we clear?

There were a few questions posed:

Despite the issue of the tanning bed not affecting your Botox treatments, the passionate response from the panel members is to avoid this practice for health concerns as well as the issue of premature aging.  We agree with this inasmuch as current research confirms an alarming rate of melanoma cases directly associated with tanning beds.

We recommend that you return to your practitioner to be evaluated for your concerns with a drooping brow.  In this way, the injector may be able to offer feedback and use this information for future treatments.

The effects of the Botox (negative and positive) will gradually wear off as time passes - approx. 3-6 months.

Lastly, you mentioned undergoing three separate treatments in a short amount of time over three treatments.  It is recommended that you avoid numerous, small treatments as this continued practice may lead to a resistance to the product.  Also, this is not the best use of your time.

Asking dermatologists whether it's ok to to back to the artificial UV radiation box after your Botox treatment is going to get you some strong responses. The reason you have wrinkles in the first place is lifelong radiation damage to the collagen and elastin underlying your skin, caused by sun exposure (and smoking if you are a smoker). If you are going to invest money in Botox and maintaining a youthful look, use another tool to lift your mood (exercise?) and give your skin a glow (bronzer, self tanner?).  Be smart!
