FAQS
What strength is Intelligent Retinol 3TR and who should use it? +

Intelligent Retinol 3TR contains 0.3% retinol – the entry-level strength in Medik8's progressive Intelligent Retinol range.

It's designed for retinol beginners or those who prefer a silky, oil-like texture. If you've never used retinol before, 3TR is the ideal starting point before progressing to 6TR (0.6%) and eventually 10TR (1%).

What makes Intelligent Retinol different from standard retinol? +

Intelligent Retinol is "intelligent" because it combines two powerful technologies:

  • Climbazole – a proven retinol booster that increases vitamin A's activity without increasing irritation
  • Time Release technology – slowly delivers retinol throughout the night for sustained results and minimal sensitivity

This means you get stronger visible results from the same retinol percentage, without the redness and peeling associated with standard formulas.

When will I see results from Intelligent Retinol 3TR? +

With consistent use, expect:

  • Weeks 2–4: Smoother texture, more radiant appearance
  • Weeks 4–8: Visible softening of fine lines, brighter complexion
  • Weeks 8–12: Firmer-looking skin, more even tone, refined pores

Results depend on your starting skin condition and consistency. Most users notice significant improvements by week 6.

Can I use Intelligent Retinol 3TR with vitamin C? +

Yes – Medik8 actually recommends using both as part of their CSA Philosophy:

  • Morning: Vitamin C serum + sunscreen
  • Evening: Intelligent Retinol + moisturiser

This proven pairing delivers comprehensive anti-ageing results. Never apply vitamin C and retinol in the same routine.

What's the difference between Intelligent Retinol and Crystal Retinal? +

The key difference is the form of vitamin A:

  • Intelligent Retinol uses retinOL – the classic form of vitamin A, ideal for beginners
  • Crystal Retinal uses retinAL (retinaldehyde) – a more advanced form that works up to 11x faster than retinol

If you've been using Intelligent Retinol 3TR comfortably for several months, you can switch to Crystal Retinal 3 for faster, more powerful results.

How long does one bottle of Intelligent Retinol 3TR last? +

One 15ml bottle lasts approximately 2–3 months with nightly use (4 drops per application).

If you're building up frequency from twice weekly, it may last 3–4 months initially. Excellent value for an advanced, boosted retinol formula.

Is Intelligent Retinol 3TR safe to use during pregnancy and breastfeeding? +

No, Intelligent Retinol 3TR is not safe during pregnancy or breastfeeding.

As a cosmetics company, Medik8 recommends avoiding all vitamin A products while pregnant or breastfeeding due to potential risks.

Safe alternatives during pregnancy include:

  • Bakuchiol Peptides (natural retinol alternative)
  • Vitamin C serums
  • Hyaluronic acid and peptide products

Always consult your GP, midwife, or dermatologist before using any active skincare during pregnancy.
