Brightening but not blinding — this serum keeps things light with citrus unshiu while tremella fuciformis (the jelly fungus with hydrating superpowers) helps your skin stay bouncy. It’s not an overnight transformation, but it gives you that subtle, “yep, my skin’s behaving” kind of glow. Apply on damp skin after toner. Safe to pair with most actives, just avoid layering with strong acids or retinol in the same routine. Lock it in with a moisturizer and slap on SPF if you're using it during the day.
