Acne can be difficult to cover with concealer; bumps may still be visible and heavy makeup can make breakouts worse. So, maybe it’s time to get rid of them for good. There are a lot of different causes of acne and it’s not exclusive to teenagers—cases of adult acne are on the rise.. IPL acne treatments, for instance, work using both blue and red light—the blue light destroys bacteria that causes acne and while the red light heals inflammation. Be sure to work with a certified aesthetic provider who can put together a personalized treatment plan and help make sure your acne-free skin lasts well past the holidays.
