You’re Mixing Formulas
When it comes to find the perfect makeup product, everyone is empowered to be their own chemist. Mixing and matching shades offers the opportunity to create your perfect match color that transitions, like your skin, with the seasons.
The same can be said for formulas; many pros choose to face map the skin and apply different formulas to the exact spots that need them. For example, mattifying products in oilier T-zones and more hydrating formulas on dryer patches. While this is a major boon for making makeup match your skin’s individual needs, rather than the other way around, there is a risk of separation if done incorrectly. Collier notes that pairing contrasting formulas together—like an oil-based product with a water-based product—can also lead to separation.
