Field Notes
Field notes from the Selene Skin laboratory on skin biology, regenerative formulation, and the 28-day renewal cycle our ritual is designed around.
How short chains of amino acids became the most precise instrument in regenerative skincare — and why molecular weight, not marketing, decides whether a peptide works.
Read →The epidermis renews itself on a 28-day cadence. Sequencing a ritual to that rhythm — not to the calendar — is what compounds results over months.
Read →Twelve-step routines were the symptom of an unanswered question. The answer is fewer, better molecules — one ritual, four essentials, deployed with intention.
Read →Photoaging accounts for up to ninety percent of visible skin change. The filter you choose — mineral zinc oxide or chemical organic — is the single most consequential decision in a longevity ritual.
Read →The stratum corneum is not a wall. It is a self-repairing, lipid-rich membrane — and the single most important structure to protect if you want your skin to age well.
Read →The skin at 7 a.m. and the skin at 11 p.m. are running different programs. A ritual that treats them the same leaves half the biology on the table.
