These topical creams and medications can interfere with the laser treatment and increase your risk of side effects. For 3 days before and after your treatment, please avoid iron pills over 65 mg. For two weeks prior to your treatment, avoid antibiotics, tretinoin/Retin-A, Aspirin, and any blood-thinning medications.
You cannot do laser hair removal if you’ve taken oral isotretinoin (Accutane) or immunosuppressants in the last 6 months.  

A bit of redness and irritation is normal after laser hair removal. To guarantee speedy, easy recovery, make sure to follow these aftercare practices. If your skin is a little irritated, you can apply a cool compress, aloe vera, or skin-soothing lotions after the treatment. Avoid any intense skin-renewing or exfoliating facial treatments, including microdermabrasion and chemical peels for at least 2 weeks before and after your laser treatment.Avoid all unprotected sun exposure. Wear sun-protective clothing or sunscreen when going outdoors in the daytime. Avoid sweating, intense exercise, or deodorant use for 24 hours after your treatment. For 24-72 hours after your treatment, avoid jacuzzis, saunas, steam rooms, or hot showers. We normally recommend you wait ten days after your laser hair removal treatment before shaving again, to avoid irritation.
