Tirtir

Q: How do I pick the right cushion foundation shade?

TIRTIR's numbering runs from lighter to deeper shades with N (neutral), W (warm), and C (cool) undertone variants — matching both depth and undertone matters more than depth alone, so check your undertone before choosing between similarly numbered shades.

Q: Does the cushion foundation include SPF?

The dedicated SPF50+ PA+++ version does; the standard Mask Fit Red Cushion has its own formula without added sun protection, so check the listing before assuming either way.

Q: Can I use the vitamin C serum with the Ceramic Milk Ampoule?

Yes — vitamin C serum in the morning under sunscreen, with the Ceramic Milk Ampoule layered in whenever the skin needs extra barrier support, works well as a combined routine.

TIRTIR is best known for the Mask Fit Red Cushion Foundation in 40+ shades, alongside a skincare line built around ceramide and centella and a standout vitamin C serum.
