The order in which to apply concealer and foundation is a topic of debate among makeup enthusiasts, but most experts agree that foundation should be applied first. Here are some reasons why:

• Foundation is meant to provide an even base for the rest of your makeup, while concealer is designed to cover specific marks like blemishes, hyperpigmentation, or dark circles. Applying foundation first allows you to even out your skin tone and use less foundation overall.

• If you have blemishes or pigmentation on your skin, its best to put your base on first. If you do your concealer first, youll just end up covering or disrupting the work you did.

• Concealer tends to have red or pink tones to counteract darker colors, so it doesnt always perfectly match your skin tone. Applying it after foundation allows you to blend it in better and avoid looking too cakey or textured.

That being said, there are some situations where applying concealer first might be beneficial. For example, if you struggle with lots of hyperpigmentation, acne, and/or super dark circles and need a big boost of coverage, applying concealer first might be helpful. Additionally, if you find that your concealer tends to smudge and migrate when you apply foundation second, you can cover problem areas with concealer first, apply powder so it doesnt move, then put your foundation on.

In summary, the general rule of thumb is to apply foundation before concealer for the smoothest and most even coverage. However, there are exceptions to this rule depending on your specific needs and preferences.
