Neutrogena Light Therapy Acne Spot Treatment - UV-Free & Clinically Proven for Sensitive Skin (1 Count) | Gentle Blue Light Therapy for Face & Body | Perfect for Daily Acne Care Routine

A few years ago, I turned 23 and started developing pretty severe cystic acne on my checks and forehead. At first I figured it was no different than the whiteheads I used to get as a teenager.Nope! Adult cystic acne is another level of painful, persistent acne. Each bump took nearly a month to disappear and there was virtually nothing I could do about it. Even worse, the cyst would leave hyper-pigmentation behind that would take another 6 months to completely fade. Even getting 6-7 cysts/month left my cheeks and forehead covered in dark marks.After several years of trial and error, I finally got my acne under control and my skin back. Neutrogena's light pen is a CRUCIAL item in my regimen. I take it everywhere. Using the pen helps me stop the last few pesky cysts that kept my skin from fully clearing up. I typically get about 2 cysts per month.How I use the pen:- I catch cysts early and this is KEY. You know when you feel the first sign of slight swelling that will eventually become deep acne? That's when I zap it. I use the pen 3-5X before bed, put a little bit of acne cream on top, drink a big glass of water and get a good night's sleep. When I wake up, the cyst is consistently gone or almost gone. Seriously, its gone. Even the worst looking contenders - if I catch it early, its gone.- If I wait until the cyst fully forms, it is too late and the pen only slightly speeds up the process. Acne is an immune response to bacteria within the pores. Cysts form as your immune system fights bacteria in deep layers of your skin. My theory is that the light from the pen, unlike topicals (ie your salicylic acid, benzoyl peroxide, retin-a), can actually penetrate the lower dermis to effectively kill bacteria that causes cysts. When I use the pen, I can see the light shining all the way through my cheek. If you kill bacteria early, before the immune system has a chance to launch all-out war, you can reverse the formation of a cyst.I love this product and it has changed my skin! This isn’t magic, but after being frustrated for so long it feels really close.Note, the pen will make a 'beep beep beep' noise when it runs out of battery. Don't buy a new pen when this happens! Get a small screw driver, replace the AAA battery and it will work just fine.
