Yimiskin and Tea — Tea and skin: which brewed | yimiskinandtea.com
Three steps in the morning, two in the evening, and a calendar measured in weeks rather than days.
The morning opens with a cleanse and a niacinamide serum. Niacinamide works in the 2-5% range; 10% is a common upper limit for daily use, not a target, and higher is not the same as better.
The morning closes with sunscreen, which is the step the whole routine depends on. At the tested dose of 2 mg/cm² — roughly a quarter teaspoon for face and neck — SPF 30 blocks about 97% of UVB and SPF 50 about 98%. Applying less than the tested dose quietly lowers the protection, which is why the quarter teaspoon matters more than the choice between 30 and 50.
The evening is two steps: cleanse, then retinol. Over-the-counter retinol products typically run 0.1-1%, and the beginner schedule starts at 0.25-0.5% on two nights per week. Frequency is increased only after the skin sits comfortably with the current schedule.

The typical failures are worth naming because they are predictable. The retinol burn — redness and flaking from starting nightly — is the most common. Pilling comes from layering too much serum under sunscreen. Over-exfoliation comes from stacking an acid on retinol nights. And early quitting comes from judging the routine before the calendar allows.
An exfoliant is an optional extra, not a sixth step. AHA and BHA products are effective at pH 3-4 and belong in the routine at most 1-3 times per week; above 10% AHA, irritation risk rises sharply. While retinol is still being introduced, exfoliant nights and retinol nights are kept on separate evenings.
The calendar closes the routine. Skin cell turnover runs about 28 days in young adults and slows to 40-60 days after age 50, so any active needs 8-12 weeks before results are judged. The tea habit described on /teas-for-skin is the easy companion during that wait — it asks only for a kettle and a timer.
