This isn't a "best of" ranking. It's what a search of FDA's own registries returns for the two devices in our catalog that carry the 415nm blue wavelength acne treatment uses.
FDA's OLP product code — Over-The-Counter Powered Light Based Laser For Acne — is the classification that covers light-based acne devices. Led Technologies Inc., the manufacturer behind the Dr. Dennis Gross DRx hardware, holds two related 510(k)s under it. Neither can be confidently matched to the retail device: the GUDID record for the mask actually sold shows its own submission number withheld, not either of those two K-numbers. That gap — a real device, a real manufacturer clearance history, no confirmable link between them — turns out to be the pattern here, not the exception. Only two masks in our whole catalog carry the blue wavelength this indication needs in the first place, and neither has a clearance record we could confirm for it.
Search by device name and by manufacturer at accessdata.fda.gov and AccessGUDID — a missing result under the retail name alone doesn't settle anything. Full search log on our clearance check page.
Flip side: on our anti-aging page, this same device IS flagged "not recommended" — same unmatched-record status either way, but there it's competing against four well-differentiated masks instead of exactly one other unconfirmed candidate. The field changes; the registry status doesn't.

Want the shortest, most repeatable routine? Dr. Dennis Gross DRx runs 3-minute sessions with a combined red+blue mode. Check price on Amazon ↗(paid link)
Want more wavelength types and a lower price, and you're not bothered by an unverified claim on the listing? iRestore Illumina adds near-infrared and costs less — see the marketing-claim row above before you decide that doesn't matter to you. Check price on Amazon ↗(paid link)
Want a device with a confirmed FDA record specifically for acne? Neither device in this catalog has one today. Check any device yourself against the FDA's 510(k) database before buying — see "Check This Yourself" above.
Not one we could confirm. Dr. Dennis Gross DRx's registry status is records exist, device cannot be matched — the manufacturer has clearance history but no record ties it to this exact product. iRestore Illumina's status is no record found under this device name in any of the three databases we searched. See our full clearance check for both search logs.
"Over-The-Counter Powered Light Based Laser For Acne" — the FDA classification behind two 510(k)s the DRx hardware's manufacturer, Led Technologies Inc., holds: K171386 and K183247. Neither is referenced by the retail device's own GUDID record, which lists its submission number as withheld. Same manufacturer, no confirmed device-to-record match — so we don't attribute either K-number to this product.
We can't confirm that from the databases. The product page carries a circular seal reading "Cleared Technology," styled to match adjacent IEC and ISO seals and labelled "Icon for FDA Cleared Technology" in the page source — but no clearance number appears alongside it, and our search of all three FDA/NLM databases returned no record under the device name Illumina.
That's not what this page establishes. We're reporting what the registries show for two specific retail devices, not a verdict on light therapy as a category. If an FDA record confirmed specifically for acne matters to your decision, neither device here provides one today — verify any device yourself before buying rather than taking a listing's word for it.
Both carry the same kind of registry gap, so FDA status doesn't separate them. What does: iRestore's own listing displays an FDA-adjacent seal with no clearance number behind it, which Dr. Dennis Gross's listing does not do. That's the basis for the ranking below, not a claim that one treats acne better than the other.
