Layering
Water-first layering vocabulary
Many guides describe thinner watery layers before richer ones - a pattern, not a prescription.
The pattern
Educational routines often place watery toners or essences before creams. That is a pattern language, not a medical order.
Sealing
Some guides place occlusive layers last to slow evaporation.
