the barrier cream$98
the daily spf$98

Double the retinaldehyde, for skin that has been on the 0.05% nightly for a season and stopped noticing it. A peptide complex replaces the bakuchiol, because at this rung the job is support rather than introduction.

Same price as the first rung. Charging more for a bigger number would make the number the product, and it is not.

Application

(01)
Only after the first rung.
Nightly on 0.05% for at least eight weeks before you move up. There is no prize for arriving early.
(02)
Drop back to every other night.
Doubling the dose resets the pacing. Build up again from there.
(03)
Sunscreen follows in the morning.
Same rule, more so.

what's in it

One active doing the work, and the ones making it bearable.

retinaldehyde 0.10%: twice the first rung, for skin already acclimatised to it.
peptide complex: signal peptides that support firmness alongside the retinal's work on texture.
squalane: keeps the barrier flexible at the higher dose.

Also made with glycerin, tocopherol, panthenol
