1.🌅30 Days of Retinal

I swapped my boring retinol for Medik8 Crystal Retinal 3 for a month. No breaks. No buffer BS.

My skin peeled exactly once (day 4, around my mouth — looked like a lizard). Then it just… worked. Faster than any retinol I’ve used in 10 years.

2.🔬What You’re Actually Buying

It’s retinaldehyde — one step closer to prescription tretinoin than retinol. £42 for 30ml. The claim that made me try it: “visible results in 7 days.” I rolled my eyes. Then I saw it.

1

Encapsulated Retinal

Stays stable until it hits your skin. No weird orange tint by week three.

2

Vitamin E + Hyaluronic Acid

Kept my face from looking like a dried apricot. Genuinely hydrating.

3

Triple-Action Delivery

Absorbs in 12 seconds flat. No waiting 20 minutes to moisturise.

3.📸What’s Actually Inside

No fluff. Four ingredients doing the heavy lifting. The rest is just delivery system.

  • Retinaldehyde: 3x faster than retinol at skin turnover
  • Vitamin E: Calms the purge before it starts
  • Hyaluronic Acid: Plumps so fine lines look softer
  • Glycerin: Keeps barrier intact so you can use it nightly

4.🤔The Real Experience

Texture is a thin gel-cream. Spreads like butter left out too long. Sinks in before you finish your other hand. First week: tingling. Not burning — just a polite reminder something’s happening.

Week 2 my chin broke out in tiny bumps. Almost quit. Week 3 they were gone and my skin looked like I’d slept 10 hours. The unexpected part? My dark circles looked lighter. Nobody talks about that.

💡

One Thing: Apply to completely dry skin. Wait 90 seconds after washing. If it stings, you’re too damp.

5.💥Did It Actually Work

Fine lines around my eyes? Noticeably softer by day 18. The deep one between my brows? Still there but less angry. Acne scars faded about 40%. New breakouts? Zero from week 3 onward.
