Can I go out in the sun right after PDT?
No. There are very specific strict sun restrictions for the treated area after Photodynamic Therapy.
You may not go out in the sun even with sunscreen for usually 24-48 hours after PDT especially after facial treatment. Arms, legs, chest or back PDT may be much easier since you can wear high SPF protective clothing and sunscreen to protect the areas during the post-procedure period..
It is important to follow your own physician’s instructions for wound care and sun protection.
I have been taking spironolactone for at least 10 years for adult acne. My eyelashes, eyebrows and body hair started falling out about 6 years ago. I was going through a very stressful period and the doctors thought it was from stress. 4 years ago, I went to my dermatologist and she increased my dose of spironolactone to 100mg daily to stimulate hair growth. I used some regrowth products on my eyelashes and most of them grew back. My eyebrows and body hair have not. My hairline has also receded slightly in the last few years. 2 weeks ago I saw my Primary care MD. I told him I'm terrified of going bald. He told me spironolactone can cause hair growth OR loss. He checked my thyroid levels, iron, B12 which were all normal. I immediately stopped the spiro and saw my dermatologist. She doesn't think the spiro is causing my hair loss. Did a biopsy of a hair follicle. I feel certain it is the spiro. No other explanation.
