above-the-mask adjective
UK /əˌbʌv.ðə.ˈmɑːsk/ US /əˌbʌv.ðə.ˈmæsk/
describes a beauty treatment or product that is used on an area of the face above where a mask is worn, such as the eyes or forehead

While the percentage of Americans getting manicures and pedicures has dropped 55% from 2019 to 2020, many above-the-mask beauty services have stayed strong. Permanent makeup (including eyebrow tinting and microblading) have remained steady year over year. BOTOX®, fillers, and similar treatments have been consistent, as well.

skin fasting noun [U]
UK /ˈskɪn.fɑːst.ɪŋ/ US /ˈskɪn.fæst.ɪŋ/
the practice of using no, or very few, skincare products on your face for a set period of time, thought by some people to be good for the skin

When it comes to putting skin fasting into practice, the options range from a complete break over the course of a few days to simply downscaling your skincare operation and opting for a more minimalist approach. Although the idea behind skin fasting sounds promising, unsurprisingly, there aren’t many professionals that advocate the complete cessation of your skincare routine.

UK /ˈsɔː.nə.blæŋ.kɪt/ US /ˈsaʊ.nə.ˈblæŋ.kɪt/
a type of sleeping bag that emits infrared rays on the inside to heat the body in a similar way to a sauna

Now the hottest bit of bed-related wellness paraphernalia to arrive is the infrared sauna blanket. This sweaty “sleeping bag” claims to bring all the benefits of an infrared sauna session without the schlep to a gym or sauna studio. You can do it in the comfort of your home, away from other sweaty bodies and without the drama of communal sauna etiquette.
