Cosmetic Interaction Data

Do products work well together?

EMETTE observes and measures how products used together — like sunscreen and foundation — perform under the same controlled conditions.

How we check

Cosmetics are rarely used alone.

Per-product copy / Real use

Ingredients and directions are written per product.

In practice, people layer several products.

Whether they work well together is hard to know from single-product information alone.

Same conditions. We check what differs.

We observe and compare the differences that appear when products are layered — under the same controlled conditions.

Side-by-side comparison of single-product and layered samples under the same light

Every result keeps its context.

We connect each observation to the product, version, order of use, and test conditions that produced it.

  1. 01 Product
  2. 02 Version & conditions
  3. 03 Order of use
  4. 04 Observation & measurement
  5. 05 Connected record

From product pairings to skin and environment.

We start with how products interact — then widen understanding toward skin and conditions of use.
