The One-at-a-Time Routine Plan
A skincare routine planner for adding new products one at a time, patch testing each one for 7 to 10 days, flagging combinations of actives for a dermatologist, and paying only for what you finish
iNaturel's Skincare Routine Planner puts your products in order and ends with one line of advice: introduce one active at a time, give skin weeks to adjust, and patch test. The Patch Test Scheduler handles one product. Nothing on the site added the two together, so a whole new routine tends to be bought, opened and started in one go, and a reaction a week later could be any of it. The One-at-a-Time Routine Plan turns that advice into a calendar: an evening routine that adds four new products, mildest first and the acid last, each after its own 7 to 10 day patch test and a settle-in, takes 87 days, 13 weeks (an example). It flags every combination of actives for a dermatologist instead of scheduling it, dates each product from the period-after-opening number printed on its own pack, prices the routine per month from your own receipts, and shows when a big 'value' jar costs more per ml you actually use ($0.90 against $0.73 in the worked example) because a third of it passes its PAO. Every figure is computed from the site's own calculators; prices, dates and sizes are labeled examples and the settle-in is named as a rule of thumb. The patch test is the American Academy of Dermatology's home test. It covers bought products only: no recipes, strengths or shelf lives, no medical claims, and it does not cover sunscreen. Included: 7 steps, a routine order card, a one-at-a-time calendar, a patch test and reaction log, a product shelf sheet, a rollout reference and a quickstart, plus a personalised sheet worked from the routine you entered in the calculator.

The plan picks up where the free Skincare Routine Planner leaves off. The planner puts your products in order and ends with “introduce one active at a time”; the plan turns that into a calendar, with each new product tested using the Patch Test Scheduler for 7 to 10 days, combinations of actives flagged for a dermatologist, every product dated against the period-after-opening number on its own pack, and the routine priced per month from your own receipts. It covers bought products only, makes no medical claims, and is not a guide to making skincare at home.
