A gray or ashy result usually means the foundation’s depth or undertone is not working with your complexion.
Smooche says its Color Changing Foundation is designed primarily for fair-to-medium skin tones, so its adaptive pigments may not produce a suitable match for every complexion.
Try one thin layer on moisturized skin and blend thoroughly, then assess it against your neck in natural daylight.
If it remains gray, mix in a small amount of a warmer/deeper compatible foundation or bronzing drops; makeup artists recommend mixing formulas to correct an unsuitable tone.
If the shade looks correct initially but becomes gray later, oxidation may be responsible; Smooche notes that skin oils, pH, heat, and the foundation formula can contribute to an ashy color shift.
