Review title is Can't use if you're undergoing fertility treatments or tanned. [SEP] “Do not use if you are pregnant, nursing, or undergoing fertility treatments.”<br /><br />“Do not treat if you have tanned skin. Tanned skin is at an increased risk of adverse effects with light-based devices.”<br /><br />These are warnings that NIRA doesn’t indicate in any of their marketing, but which are included in the booklet you receive with purchase. The tanned skin comment is contrary to information on their website saying it's for all skin types.<br /><br />I purchased the device (not the serum) directly from the manufacturer for $200. They seem to offer a lot of promotions, so don’t buy this at full price (current msrp is $400, and they seem to offer 30% off all the time if you give them your email, my 50% off was a link from an influencer’s page on youtube). Tried reviewing on the main device page and got this notice: “Amazon has noticed unusual reviewing activity on this product. Due to this activity, we have limited this product to verified purchase reviews.” So that should tell us something about the quality of the reviews here. I can’t offer a review myself of the actual product because of the surprise contraindications. I had to give a star rating in order to post this review, so I just plugged in 3.<br /><br />Also, the website says to wait 1 minute before re-treating an area; the warning label says to wait at least 1 hour.
