How it works
This runs a serum texture rather than the thicker, whiter cast typical of a standard sunscreen cream, built to layer under makeup without pilling. It is meant to be the last skincare step before makeup, applied once every other product has had time to absorb so it sits on a settled surface. This particular listing is the 50ml size TIRTIR sells for the line, packaged and formulated for the Korean market rather than a separate US release.
Key benefits
- Serum texture rather than a thick, cast-prone sunscreen cream
- Layers under cushion or foundation without pilling
- Built for everyday wear, not just outdoor activity
- Sold as TIRTIR's authentic Korean-market formula, the same version sold through Korean retail rather than a US-reformulated substitute
How to use
- Apply as the last skincare step before makeup, using roughly a fingertip's worth spread evenly across the face and neck.
Will this leave a white cast under makeup?
It is built with a serum texture specifically to minimise the cast and pilling that thicker sunscreen creams can leave under a cushion or foundation. This is general guidance rather than a fixed rule, so adjust it based on how your own skin or the product itself responds.
Can I use this as my only moisturizing step in the morning?
It is formulated to sit as the last skincare step before makeup rather than to replace a separate moisturizer, so most routines still use a lightweight moisturizer underneath. This is general guidance rather than a fixed rule, so adjust it based on how your own skin or the product itself responds.
Is this the same formula sold in Korea, or a version made for the US market?
This is TIRTIR's Korean-market formula, sourced and shipped with its original Korean-market packaging and batch coding rather than a separate US-reformulated version. Korean Pharmacy stocks the exact SKU sold through Korean retail rather than a substitute built for US shelves, which is the point of buying from a specialist rather than a general beauty retailer.
How should I store this to keep it in good condition?
Keep the cap or compact closed between uses and store it away from direct sunlight and heat, the same way you would any cosmetic. A cool, dry spot such as a drawer or cabinet keeps the texture and finish consistent for longer than leaving it exposed on a warm windowsill or in a hot car.
