When interviewing Dr. Dennis, he reiterated that the mask should definitely be used before applying any skincare formulas. “Light therapy should be done on a clean, dry face. Applying topical products beforehand will block the LED from penetrating the skin, and you won’t see the best results,” he explains.
Above all, I appreciated the convenience and the comfortable fit. Unlike other LED face masks I tried, this model is completely cordless, which meant that I could easily go about my day without having to carry the battery or a wired control panel. Admittedly, the mask felt a bit heavier that I expected, but since I got used to it, it proved surprisingly comfortable. Most importantly, it didn’t slide off the face and the fit naturally hugged my facial contours.
He also told me that “consistency is key,” which is why I was committed to using it every single day – rain or shine. That said, it’s worth keeping in mind that LED face masks don’t exactly deliver instant results, so the best thing to do is to be patient and trust the process.
With that in mind, I haven’t noticed any significant improvements until week three, which is when I’d observed a more even skin tone, less redness and a healthy-looking glow. I did two LED sessions every day – one red and one blue. And on days when I was in a bit of a rush, I opted for the combined mode.
Before using the Dr. Dennis Gross LED mask, I was struggling with a lot of PCOS-related breakouts (to the point when no amount of retinol serum made any difference). Luckily, using the blue and the combined modes definitely helped accelerate the healing process, and the red light helped reduce inflammation.
This is supported by Zeichner. Another benefit of adding this to your skincare routine is that it both works with and amplifies whatever you’re already using; in fact, you’ll see more results if you pair it with your usual regimen. Zeichner recommends it in conjunction with common topical ingredients like benzoyl peroxide, while Weiser notes that you can combine it with oral medications like birth control or spironolactone.
While I’m still in my 20s, I can’t exactly report on the youth-boosting benefits, but I definitely observed a difference to how plump and bouncy my skin looked like after three months of consistent use.
An entire year later, I’m confident in saying that I can’t imagine my routine without this clever device. My skin looks naturally radiant (which is a rarity given I have dry skin), I’m experiencing less rosacea flare-ups and my post-acne dark spots appear significantly more faded.
Does the Dr Dennis Gross LED face mask help with acne?
Yes. The Dr. Dennis Gross LED mask is the type of daily product that works as an acne treatment and prevention in one, provided you’re patient and consistent.
“It will work better for inflammatory blemishes but it can help heal and restore all acne-prone skin,” says Weiser. “Acne should show early signs of improvement in two to four weeks of light therapy, but it will take two to three months of consistent treatment for optimal results.” (The brand also states upfront that a proper course of treatment should last at least 10 weeks, although you’ll start seeing the benefits well before that).
Dr Dennis Gross LED face mask: cons
TBH, there are few that I found. I noted above that the face mask felt heavier than expected – something which I didn’t find with lightweight models like the CurrentBody Series 2 mask. Further, given how chunky it is, I’d like to do more investigation into whether the mask sits the correct distance away from the face to serve the best results.
