40. They exfoliate often
Exfoliating the skin has a myriad of benefits. In this case, the most notable interest would be preventing the build-up of dead skin cells on the surface of your skin. Clogged pores are one of the last things anyone conscious about their skin wants.
The real trick, however, is exfoliating just enough. Doing it once a week should be enough for most people. Adverse long-term effects include weakening the skin so that it wrinkles more efficiently, rather than merely clearing out the pores. It can also lead to a lot of irritation since you’re constantly getting rid of the skin’s top layer before it can fully heal.
