A standardised skin sensitivity score for modern cosmetic formulas.

Give founder-led beauty launches and enterprise formulation portfolios the same clean language for pH stress, active burden, and delivery-driven irritation pressure.

Request a private evaluation key by email, run one complimentary formulation screen, then upgrade the same credential into full reporting access when the team is ready.

No new data required

SSS uses inputs most formulation teams already maintain: pH, active levels, and delivery format.

Built for portfolio clarity

Score one launch SKU or normalize an enterprise pipeline against the same 1-5 scale.

Commercial from day one

Email-issued access keys, usage controls, billing, premium PDF reports, and shareable links already sit inside the same workflow.

Indie Beauty Teams

Use SSS to pressure-test launch formulas, sharpen positioning, and turn safety conversations into a cleaner trust signal.

Enterprise Formulation Groups

Use one scoring language across R&D, regulatory, marketing, and portfolio management without changing your core lab workflow.

Framework

One score, three formulation signals.

Pillar A

pH stress

Pillar B

Highest ingredient reactivity pressure

Pillar C

Delivery-driven exposure
