Question: How can I get rid of a foundation mustache?
Answer: A mustache of foundation is definitely never in, and can give you the illusion of having an actual mustache—which you may very well have (and not realize). Almost everyone has fine hairs above their upper lip, and these hairs become coated with foundation when applying it in certain ways. However, there are many solutions for what you’re going through, and they’re all easy fixes.
The first step is to evaluate your technique: are you applying your foundation upward and downward, side to side, almost like you’re painting your skin? If so, it’s time to change it up. Applying foundation upward and sideways coats all of the little hairs that lie flat against your face, making them stand out ten-times more than they usually would. Always drag or stipple foundation down against your skin, as this greatly minimizes over-coating the peach fuzz on your face. In addition, never powder the foundation applied to your upper lip. The foundation is already going to be atop the hairs there, and adding powder is going to magnify them like you would not believe!
If your technique is on point, the next thing to do is, well, examine your upper lip. Is there a visible layer of fine, baby-like hair there? If so, you’ve just met your culprit. Even if the hair seems transparent, if it’s clearly visible without makeup (meaning it’s pretty dense) it will still collect a lot of foundation no matter how you apply it. I recommend using a facial hair remover cream, as that is the most fool-proof, at-home fix. Waxing is another option. There are also other more permanent methods of removal via lasers and electrolysis.
Hair removal too invasive for you? Vouch for a makeup sponge like the Beauty Blender. This applies foundation much differently than a brush or fingers would, and using it damp makes it easy to blend out and apply thin layers wherever necessary.
If your foundation is truly wearing off of your face and sticking like a pro to your upper lip, then I suggest avoiding foundation on your upper lip all together. However, if you are using a foundation that’s a bit darker than your skin tone (due to fake tanning, or your face just being lighter than the rest of you) and you absolutely need to apply it to your upper lip to avoid that area looking too pale, I recommend mixing it with concealer or using a lighter foundation there. You could also take this opportunity to try out mineral foundation, as it tends to not stick to the hairs on your face.
Finally, if you suspect the problem above your lip could be hyper-pigmentation, then apply a long-lasting concealer there (like this one by MAC) and just dab over it with the foundation that is left on your brush or sponge.
