1.💡Fading the Past

My sunspots from 2018 are officially on notice.

This isn’t a general glow serum — it’s a targeted fade treatment disguised as one. The difference is in the strategic layering of brighteners.

2.🔬The Clean Claim

It’s from Beauty of Joseon, costs about $18, and promises a “clear canvas.” I tried it because they swear it’s clean beauty. Let’s see.

1

Glutathione + Niacinamide

The two heavy-hitters for interrupting melanin production.

2

Rice Bran Water

A hydrating base that’s less irritating than plain water.

3

No Essential Oils

Crucial — fragrance is a major irritant for spot-prone skin.

3.Ingredient Intel

Glutathione is the body’s master antioxidant — it tells pigment cells to calm down. Niacinamide blocks pigment transfer to skin’s surface. Together, they work from the inside out.

  • Glutathione: The internal antioxidant that tells melanin to stand down
  • Niacinamide 2%: Blocks pigment travel to skin’s surface
  • Rice Bran Water: Soothes and hydrates without clogging
  • Licorice Root Extract: A gentle brightener that doesn’t cause rebound darkness

4.💧Skin Feel & Reality

Texture is a dream — like slightly viscous water. Absorbs in 3 seconds, truly. No tackiness.

Week 3: My skin looked more even-toned before individual spots faded. A subtle unified brightness first — then the spots started to soften. Patience is key.

💡

One Thing: Apply it to damp skin right after cleansing. The hydration helps the actives penetrate deeper for the spots.

5.📊The Spot Check

My post-acne marks faded about 40% in 6 weeks. A stubborn decade-old sunspot lightened maybe 15%. It won’t erase history, but it definitely edits it.

You have fresh PIH (post-inflammatory hyperpigmentation) or diffuse sun damage.

💰

Absolutely. The price for this ingredient lineup is wild.
