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.
Apply
Apply 1-2 pumps evenly across face.
Under eyes
Gently pat a small amount under the eyes to target dark circles.
Layer
Use SPF during the day.
For enhanced results, pair with C³ Glow Veil Defense Serum.

Most high-performance skincare makes you choose: potency or gentleness, results or comfort. DEAU eliminates the tradeoff. Our formulas treat powerfully and protect deeply for long-term skin health.
Powerful actives that visibly improve skin concerns.
Soothing ingredients that strengthen and protect.
Each DEAU formula includes Japanese botanical extracts, carefully curated to reflect a formulation mindset rooted in balance, restraint, and respect for skin—principles central to Japanese skincare.
Yes. Apply DE-SPOT first, let it absorb, then follow with retinol.
Yes. The Offense–Defense Skincare™ buffers actives with soothing ingredients to maintain comfort throughout treatment.
Most target one pathway. De-Spot addresses all three stages of pigmentation while protecting the barrier so correction can continue.
Consult your doctor. De-Spot contains azelaic acid, which is generally considered safe, but we recommend checking with your healthcare provider.
Most see visible improvement within 4–6 weeks of consistent use.
My skin tone is noticeably more even at 2 months and my post-acne marks are significantly lighter. Only complaint is the bottle size. Using it morning and night it goes faster than I expected. Wish it came in a larger option.
Month 3 and my skin keeps getting better — not worse. I've never been able to say that about a brightening serum.
Everyone says give it 6 weeks. Mine started changing at week 3. The edges of my spots got softer and less defined. By week 6 I was in a completely different place than I expected to be. Really happy with this.
I have combination skin and was hoping for faster results honestly. The first month I saw almost nothing. But by month 2 my PIH was visibly lighter and my skin tone more even. It's working, just slower than I'd like. Texture is great though — absorbs instantly.
I'm really particular about skincare and have high standards from years of using Japanese and Korean products. This holds up. The texture is refined, it absorbs completely, and the results on my PIH have been real and consistent over 2 months.
I have oily skin and the texture on this is perfect for me. 2 pumps, absorbs in literally seconds, no residue. My dark spots are lighter at 6 weeks and my pores look less congested overall which I wasn't expecting.
I got a pretty bad breakout in January and the marks it left behind are already significantly lighter at 6 weeks. Way faster than marks from previous breakouts at the same timeframe. Something is working differently with this serum.
My skin is reactive and I was really nervous to try something new. Patch tested for a week, zero issues. 6 weeks in and my PIH from hormonal acne is lighter without my skin ever getting red or irritated. That combination is hard to find.
