Did anyone have a bad outcome from using an LED lamp on clients?
After completing 15 minutes of red light therapy on a client she called later in the day and complained of a sunburned appearance along with hyperpigmentation.
I later found the client was using a topical antibiotic for acne and my dermatologist said it made the skin more light sensitive.
This is a great point about lemon and grapefruit extracts in skincare. I use a Wood's skinscope during my initial facial (and again later to compare the pics) and I can often track low-grade irritated, barrier-compromised skin back to these photosensitizing extracts.
