Beauty of Joseon Stay Fresh Tone-Up Sunscreen Purple SPF50+ PA++++ 50ml combines daily high-level sun protection with a subtle color-correcting tone-up effect. Designed for dull, tired or yellow-looking complexions, the Purple version uses a soft lavender-purple tint to help visually balance sallow tones and create a brighter, fresher and more even-looking complexion. It can be worn on its own for a natural tone-up effect or underneath makeup as a complexion-perfecting sunscreen base.
