The Shark CryoGlow is the most feature-complete mask here: all three evidenced wavelengths, two disclosed clinical studies, and genuinely useful under-eye cooling — from a mainstream brand at a sensible price.

#Strengths and trade-offs
Strengths
- All three evidenced wavelengths in one device
- FDA cleared with two disclosed 12-week studies
- Distinctive under-eye cooling; strong value from a major brand
Trade-offs
- Corded (the cooling needs power) and bulkier
- Rigid design won’t conform like silicone
- Newer to skincare — long-term reputation still forming
#Three wavelengths plus a real extra
The CryoGlow covers 415 nm blue, 630 nm red and 830 nm deep-infrared, so it addresses both ageing and breakouts in one device. Shark also discloses two 12-week clinical studies (brand-run, but disclosed — more than most mid-price rivals manage), reporting improvements in fine lines and firmness by eight weeks and clearer skin by four.
The stand-out is InstaChill under-eye cooling, which de-puffs and is the rare “extra” that does something you can feel. Sessions are a short eight minutes.
#Living with it
The catch is the design: it is a rigid, corded device (the cooling needs power) rather than flexible silicone, so it won’t conform as closely as our top picks, and it is bulkier to store. If you want mainstream support, three wavelengths and de-puffing for around £300, it is excellent value.
#How we scored it
Frequently asked questions
Is 415 nm blue light on the Shark CryoGlow good for acne?
It targets acne-causing bacteria, and can modestly reduce inflammatory lesions. But independent reviews rate the overall evidence for blue light on acne as weak, so treat it as an adjunct, not a cure — see our red vs blue guide.
Does the under-eye cooling actually help?
It de-puffs and feels pleasant, which aids adherence. It is a comfort and cosmetic feature rather than a proven long-term skin treatment.
