    • Really works
I’ve been thinking about trying this for far too long. Finally gave in and bought it. It really works. My adult acne is almost gone. Granted I’ve only have been using it for only one week. Shoulda bought it a long time ago

    • This worked wonders for me.
I suffer from adult acne and have tried numerous treatments. Most are too harsh for my skin and wind up making the acne worse even products with retinol. I bought this hoping it would make a difference. It has. It says you can use this with regular acne products but I don't. For me it took about a week before I noticed a difference. When I arrived, I had broken out pretty badly including cystic acne. I used this twice a day for 3 minutes on the trouble spots. Within a few days, I noticed healing and within a week, almost all the original acne was gone. I've kept using it and any flare ups are usually gone after one or two treatments (a day or two). I've not had a really bad case of cystic acne breakout since that first week and I haven't had a 'bad' breakout while using it. It appears to be working really well for me. I've not had the hyperpigmentation mentioned. There were a few days where I'd used the lightstim a little bit longer than 3 minutes in a few areas and when I pulled it away, there were indentations and marks where the device had been against my skin. Those took a couple hours to go away. I stopped doing longer sessions in the morning to prevent that. This does get somewhat warm as it approaches the 30 minute shut off. It's not painful but if your skin is really sensitive, you might want to use this in shorter sessions. ... show more

    • Doesn't Work & Limited Return Policy
Not only did this product not work for my acne, but the company is very strict about their 90 day satisfaction guarantee. I called within six months of my purchase because I did not have much need to use the product during the first 90 days and explained this and was shut down repeatedly with a generic "sorry you are out of the window for returning this item." I was very disappointed by this and it clearly shows the company does not stand behind their product. ... show more

    • Best defence against acne!
Love LightStim - Years ago our oldest son had very inflamed acne. We used the Blue LightStim device and after the inflammation went down we followed up with microdermabrasion. Acne was gone for good! Now my youngest son (who has autism) is having the same challeges. I give it 4/5 stars for two reasons. First - our first device was rechargeable, this one must be plugged in the entire time. It limits the comfortable spaces we can perform treatments. Second - this device has individual lights that touch the skin and it is hard to santize or wipe with alcohol between uses. We purchased disposable ear covers (clear stretchy plastic) to put over the device so we don't transfer any bacteria between uses. ... show more

    • Great Purchase!
This device saved me during a hormonal acne out break. I used it daily and it helped tremendously when i couldn’t use strong medications due to pregnancy! Easy to use and cuts healing time in half!

    • Works!!
This worked wonders for my hormonal acne. I used it at least 5 times a week for 2 months and experienced a dramatic reduction in breakouts. Additionally, any breakouts that did appear would disappear within a day or two. After two months of using 5+ times a week, I went down to 3 times a week for a month, then once a week for a month, now I use it once maybe every other week for maintenance. My skin is pretty much perfectly clear now. And it’s tone and evenness is much better. Also BONUS!!! It helps fade bruises faster. I use it when I get a bad bruise (I bruise easily) and it breaks up the bruise in a few days (using for 10-15 min on the bruise each day). Typically it takes two weeks for bad bruises to mostly heal on me. So using this on bruises has been significant for me. ... show more

    • not worth it
This is overpriced and was not worth it. It is tiny and doesn’t make any difference at all. Save your money.

    • Totally worth it!
I very rarely (if ever) write reviews but this product truly deserved one. I noticed during the school year last year that my acne started getting worse, edging between mild and moderate. It wasn't completely obvious to everyone else but it drove me crazy and was something I really wanted to deal with over the summer before heading back to school. I tried dermatologist recommended creams, facials, etc...and I do think it was a combo of all of that that ending up working BUT I didn't start seeing results until I started using the LightStim. I use it while I watch TV, it takes like 30 ish minutes, and makes my skin look and feel so much better (even my family noticed a difference)! ... show more
