1.🔬Space-Grade Skin Rewiring

NASA-grade ingredients in a $600 serum sounds like marketing nonsense. I was ready to hate it. But then I actually read the ingredient list, and it’s… legitimately weird science.

This isn’t a moisturizer with sparkles. It’s a targeted repair serum that uses a modified “celestial” black diamond — yes, actual crushed diamonds — to allegedly convert light into cellular energy. Wild. But the delivery system is what hooked me.

2.💎The $600 Gamble

111Skin calls this the “Celestial Black Diamond Serum.” It’s a dark, glittering liquid that costs more than my rent for a tiny bottle. The claim that sold me: it repairs skin while you sleep by “rewiring” your cells’ natural repair cycle.

Black Diamond Fermentation

Crushed diamonds fermented with yeast — sounds insane, but it’s designed to boost cellular ATP production

Time-Release Capsules

The active peptides are locked in micro-spheres that burst at 2am when your skin is actually repairing

Zero Grease Factor

It dries down to nothing — no oily film, no sticky residue, just a matte, velvety finish

3.🧪What’s Actually In It

Forget the diamond hype — the real actives are boring-sounding but powerful. It’s got a peptide complex that mimics your skin’s natural repair signals, plus a patented antioxidant blend that doesn’t just neutralize free radicals — it stops them from forming in the first place.

Fermented Diamond Extract: Unproven but seems to increase skin’s natural glow response
Niacinamide 5%: Calms redness and shrinks pores without irritation
Sodium Hyaluronate: Lightweight hydration that sinks in, not sits on top

4.📊The Texture Reality Check

It’s water-thin. Not a serum texture at all — closer to a toner. You need 3-4 drops for your whole face, and it absorbs in about 15 seconds. Zero fragrance, which I appreciate because my skin hates perfume.

Week two, I noticed something weird: my pores looked… smaller? Not tightened — just less noticeable. Like the skin around them had plumped up. That’s when I stopped rolling my eyes.

One Thing: Press it into your skin with your palms, don’t rub. The heat activates the time-release capsules faster.

5.🔍The Honest Results

After 4 weeks: my morning redness is down 60%. My skin bounces back from a late night — no more 3pm zombie face. But it didn’t erase my fine lines, and the diamond thing is still a luxury gimmick.

✅

Buy if

Your skin looks dull and tired no matter how much sleep you get — this gives that lit-from-within effect

⏭️

Skip if

You’re dealing with active breakouts — this won’t fix acne, and the price is criminal for that

💰

Worth it?

If you’ve got the cash, yes. If you’re stretching, buy a retinol instead — 80% of the effect for 10% of the price.
