Topic: Medik8 Crystal Retinal 3: 30-Day Honest Test Results
Product: Crystal Retinal 3
Brand: Medik8
Hook: I used a retinaldehyde serum every night for a month and photographed my skin each week — here’s exactly what changed.
Angle: 30day_honest_test
Day 3 my chin peeled like a snake. Not cute. But by day 30? My foundation actually stayed put instead of settling into every tiny line.
The real tell was my boyfriend asking if I was wearing makeup when I wasn’t. That never happens.
This is a retinaldehyde serum — one conversion step closer to retinoic acid than standard retinol. So it works faster but supposedly with less irritation. Medik8 calls it “Crystal Retinal 3.” It’s $65 for 30ml. I bought it because I’m impatient and wanted results in weeks, not months.
Time-Release Technology
Microencapsulated retinal — so it doesn’t hit your face all at once like a wrecking ball.
Stabilized Formula
Vitamin E keeps it from oxidizing in the bottle. Smells faintly of nothing, which is a win.
3 = Strength
This is entry-level. 0.03% retinal. Perfect for newbies who don’t want to cry.

Three active ingredients doing the heavy lifting. No filler nonsense. The peptide is the surprise MVP here — it’s what kept my skin from looking angry.
- Retinaldehyde: Speeds cell turnover — the real anti-aging engine
- Peptide Complex: Soothes the irritation retinal usually causes
- Vitamin E: Antioxidant shield + stabilizer
- Hyaluronic Acid: Holds water so your barrier doesn’t collapse

Thin yellow liquid. Absorbs in 10 seconds flat. No greasy film — I could slap moisturizer on immediately. Smells like nothing. That’s rare for actives.
Week 2 I got three whiteheads on my jaw. Classic purge. Week 3 they vanished and my skin looked… calm. The weird part? My forehead felt smoother than my cheeks by day 18. Cheeks are still catching up.
Fine lines around my eyes are visibly softer. My pores didn’t disappear (they never do). But my texture is noticeably more even — that bumpy stuff on my chin is gone. Hyperpigmentation from an old breakout? 40% lighter. Not gone, but lighter.
It’s not magic. But it’s the closest thing I’ve found to actual progress without a prescription. I’ll finish the bottle and buy the next strength up.
