Most skincare adds more.

"INBAR+co builds skin support systems: formulas refined through spa practice, ordered around how skin functions, and made with responsible chemistry instead of lazy natural-versus-synthetic claims."

the living formulations
system

Most skincare is finalized before it meets real life.

Ours begins closer to use. Daniella formulates for professional-use logic, then the formulas are refined through the Resonance Marin spa environment, production feedback, service feedback, and quality control before becoming retail skincare. What disrupts is removed. What underperforms is replaced. What proves consistent remains.

02
responsible chemistry

Not natural.
Not synthetic.
Correct.

Natural is welcome when it performs. Lab-made is welcome when it is safer, more stable, or less wasteful. We choose by function, not category. "Clean" is an exclusion list. "Natural" is an origin story. Neither tells you whether an ingredient actually works. And neither accounts for what natural ingredients can cost the planet: monoculture farming, biodiversity loss, supply chains that damage the ecosystems they depend on.

03
skin integrity

protect first.
improve second.

Skin performs best when its core systems are intact.

The skin is a working system. Barrier, acid mantle, and microbiome. The bacteria that live on healthy skin produce the acids that maintain the pH that keeps the barrier-building enzymes active. Disrupt one, the rest follows. Most skincare disrupts the system in the name of improving it. High-pH cleansers strip sebum. Over-exfoliation flattens microbial diversity. Layered actives on a compromised barrier accelerate the symptoms they were meant to address. Skin Integrity reverses the sequence. Support the barrier. Preserve the microbiome. Respect the pH. Improvements follow.

Formulation does not end at the formula. Packaging, sourcing, production, and shipping are treated as design constraints, not marketing claims. Aluminum primaries, FSC-certified paper, 100% plastic-free by default packaging, zero petrochemical derivatives, and 100% renewable energy are part of the system.

Read: Our material standards
"I built INBAR+co because I could not find skincare I trusted. Clean was too often an exclusion list. Sustainable was too often a claim without measurement. And too many formulas were finalized before they ever met real skin. So we built a different system: slower, more disciplined, and released only when the formula consistently held."Daniella Inbar, Founder + Formulator

build the skin
that needs less.

Every principle on this page lives in the formulas: better order, fewer unnecessary inputs, skin integrity first, and claims measured before they are made.
