Dark spots don’t form one way so targeting just one thing won’t fix them.
De-Spot works at every stage of how dark spots form: before pigment starts, while it’s being made, as it rises to the surface, and after—calming the inflammation that keeps discoloration coming back.
The result: luminous, bright, even skin tone.
Treat powerfully:
Tranexamic acid — targets pigment at the source.
Azelaic acid — calms redness while brightening.
Niacinamide — stops pigment from reaching the surface.
Three actives. Three stages of correction.
Protect deeply:
Ushio Onsen Water — mineral-rich Japanese hot spring water.
Squalane — lightweight, never heavy.
Vitamin E — protects while the actives work.
Brightening doesn't work if your skin can't tolerate it.
Most brightening serums make you choose: push hard and irritate your skin, or go gentle and wait forever for results.
De-Spot does both. Four stages of correction. Barrier protection built in.
Results that build without the setbacks.
For best results, apply De-Spot morning and night after cleansing.
