Order rule of thumb: thinnest to thickest. Cleanser, then water-thin toners and acids, then serums, then treatments, then moisturizer. In the morning sunscreen goes on last. At night an occlusive (if you use one) goes on last.
Formulas are complete routines built around one face type. Each one lists the morning and night order, how often each active runs, a budget build and a med-grade build. Press Load into Lab to put it on your shelf and watch it work.
Tiers. Drugstore = sold everywhere. Derm brand = dermatologist-developed, widely sold. Med-grade = sold through physicians, med spas and authorized retailers. Rx = needs a prescription. Formulas checked against brand and label listings in September 2026; brands reformulate, so check the box you buy. Nirvani is not paid by any brand listed.

Skin tone (Fitzpatrick)
