The single-active idea
Most bottles hide one working ingredient behind a dozen that do little. We do the opposite: a single, clinically-studied active at a meaningful concentration, so you know exactly what's on your skin and why.

The specimens
Each one a single studied active, labelled like the lab specimen it is.
SmoothLot · AH-08
Argireline
Acetyl Hexapeptide-8
A peptide famous for softening the look of fine lines where you move most: forehead, brows, and the corners of your eyes. It works on the surface to relax the appearance of repeated expression, so skin looks smoother and more rested over time.

Why single-active
Skincare shouldn't be
a guessing game.
When a formula does one thing well, you can actually tell what's working, and build a routine on evidence instead of marketing.

How it works
The Seralune ritual
01 / Cleanse
Cleanse
Start with clean, dry skin so each active absorbs without interference.
02 / Drop
Drop
Two to three drops of your chosen active, morning and night. Patch test first.
03 / Layer
Layer
Seal with moisturiser. Finish daytime routines with SPF.
