Oily skin: foaming gel. Dry or sensitive: creamy wash.
The why

The why
A beta-glucan serum with a very short, humectant-heavy formula that people use for dehydration and barrier recovery. It layers well on damp skin and suits tret users, but reformulation complaints and occasional breakouts are real.
One minus

The why

For dehydration, Redditors most often reach for the Laneige Water Sleeping Mask for its effective hydration and lightweight gel texture. Other overnight masks praised include those with soothing and nourishing properties, like the LANEIGE Cica and rice probiotics masks.
The why
A hyaluronic-acid-heavy sheet mask that drenches dehydrated skin and sits nicely before makeup. People use it after tret nights, heat waves, and flare-ups, but a few reactive users report irritation or a bad HA reaction.
One minus
Reactive skin can get a bad HA reaction
