Quitting Alcohol
Removes a vasodilator, a diuretic, a sleep disruptor and several hundred empty calories at once. The facial change over a month is one of the most visible in this index.
Also called: sober face · quitting drinking skin · dry january face
Verdict — legit
Does what it claims, with evidence behind it.
Evidence grade B
At least one good randomised trial, or consistent findings across controlled studies.
Mechanism
Ethanol causes cutaneous vasodilation and facial oedema, suppresses ADH, fragments REM sleep, and depletes zinc and B vitamins — each independently degrading skin tone and periorbital appearance.

The full read
This is unglamorous and it outperforms most things people buy. Regular drinking is independently associated with facial ageing in large cohorts, and the short-term effects — puffiness, erythema, flushing, sallow tone, dark circles from disrupted sleep — start reversing within two to four weeks. There is also a compounding effect: alcohol sabotages sleep, and sleep is the other highest-ROI item in this library. If you are looking for the highest-impact free intervention available and you drink regularly, this is it.
