IN 1973 Circadian Peptide System™

Includes one AM Peptide Serum Mist and one PM Peptide Serum Mist.

A biology-first skincare system developed for skin after daily grooming.

Most skincare is designed to moisturize. The Circadian Peptide System™ was developed to support skin during the period immediately following shaving, trimming, cleansing, or any routine that temporarily disrupts the skin barrier.

Rather than adding more steps, we focused on what the skin is biologically trying to do during recovery.

The formula combines carefully selected peptides, barrier-supporting ingredients, and hydration technologies into a single daily system designed to work with the skin’s natural repair processes.

Developed around three principles

• Support the skin barrier after grooming.

• Help replenish hydration without feeling heavy.

• Respect the skin’s natural biology rather than overwhelm it.

Designed for

• Daily post-shave care

• Freshly cleansed skin

• Morning or evening routines

• Anyone looking for a simpler, biology-first approach to skincare

Because biology doesn’t stop when grooming does.
