Night time is when the skin does its heavy lifting .
Like the rest of the body, skin does the bulk of its repairing, restoring, and regenerating while we sleep, so night creams are focused on moisture and recovery . They contain the most powerful , slow-absorbing moisturizers that are designed to penetrate over the course of several hours ; since there’s little to no concern about sun exposure, they also contain the highest concentrations of anti-aging compounds ingredients like retinol, glycolic acid, and hyaluronic acid which are able to do their work without interference from sunscreens.
The result is that night creams are often richer, thicker, or heavier than day creams . Of course , we don’t mind much , since most of us don’t wear makeup to bed , and the cream is usually absorbed by the time we wake up.
