Following treatment with the laser, are there any restrictions on my activity? You'll find your sessions are so mild that you may return to your normal activities immediately. As always, it is a good idea to limit your sun exposure prior and post treatment. The use of sunscreen is always advised, especially on treated areas. Also, as some antibiotics heighten the skin's sensitivity to light, you may choose to postpone laser treatment if you are taking antibiotics, or have taken them 14 days prior to your session.
