03Notes from the field
p. 18
★★★★★

Three months in. The fluorescent-light test in my bathroom is humbling, and I look back at it less.

Firming-Brightening No. 14
★★★★★

I've used everything. This is the first peptide serum that didn't pill under SPF and actually changed the texture of my cheeks.

Ines L. · age 47
Restoring No. 09
★★★★

Skeptical of personalisation as a category. Won me over by reformulating around my retinoid without me asking.
