Can I use this cream under makeup, or will it make my foundation pill or slide off?

Yes, you can use this cream under makeup. According to the product description, one of its suggested uses is in the morning when makeup sits better on a smoother base. The mink oil helps form a light protective layer that improves moisture retention, which can prevent a dry, flaky texture that sometimes causes makeup to cling unevenly.

For best results, apply a moderate, even layer and allow a couple of minutes for it to absorb fully into the skin before starting your makeup routine. Using too much product may leave a residual film that could interfere with foundation adhesion. If you find your makeup isn't setting as well as usual, try reducing the amount of cream or gently blotting any excess with a tissue after waiting for absorption. This cream is particularly suited for times when your skin feels like it needs that extra layer of nourishment to look and feel smoother before applying other products.
