Can I apply makeup over sunscreen ?
Ideally not, since applying anything rubs of the protective sunscreen layer.
However, if you must, foundation should be gently patted on with fingers or sponge, and powder should be patted on with a brush. Avoid rubbing !
But Sunscreen makes my face look greasy !
Try cornstarch or potato starch
. It is one of the best mattifiers ever.
Can makeup destabilise my sunscreen ?
Yes. This means that certain ingredients in the sunscreen may undergo a chemical reaction with ingredients in makeup. This renders the sunscreen ineffective, and may release harmful chemicals into your skin. If your sunscreen contains Parsol 1789 (Avobenzone, Buthyl Methoxydibenzoylmethane, avoid:
- octyl methoxycinnamate (popular UVB filter in foundations),
- zinc oxide
- titanium dioxide
- some CI colorants
However, you can use foundation and powders in which the pigments- iron oxides are coated in silicone, since they will not interact with sunscreen ingredients.
As a matting powder you can safely use foodstarchs: potato, corn, rice, arrowroot, tapioca and maranta
. To improve the colour, you may add a little cinnamon.
