Question 1

Why does foundation turn orange on my face?

Accepted Answer

Foundation oxidizes orange due to chemical reactions between formulation pigments, facial sebum, and oxygen. A shade with excess warm or peach pigment on neutral or cool undertones darkens and shifts hue as it dries down.

Question 2

Where is the best place on the face to match foundation?

Accepted Answer

The most accurate area to match foundation is the lower jawline transitioning directly into the upper neck. Matching cheeks introduces surface redness and flushing, while the inner wrist lacks natural facial melanin exposure.

Question 3

How does BaseTone calculate foundation color matches?

Accepted Answer

BaseTone ranks eligible foundation catalogue shades by ascending CIEDE2000 colour difference from the calibrated skin LAB reading. Formula, finish and oxidation are descriptive information and do not change the ranking.
