What Is Retinol and Why Does Your Skin Need It?
Retinol is a form of vitamin A that's considered the gold standard in anti-ageing skincare. This powerful ingredient works by accelerating cellular turnover, helping to reveal fresher, smoother skin whilst stimulating collagen production for firmer, more youthful-looking results.
Key Benefits of Retinol:
• Reduces fine lines and wrinkles by boosting collagen synthesis
• Improves skin texture through enhanced cell renewal
• Minimises pore appearance by keeping them clear of debris
• Evens skin tone by addressing pigmentation and dark spots
• Helps with breakouts by preventing clogged pores
Retinol vs Retinal: What's the Difference?
Whilst both are vitamin A derivatives, retinal (retinaldehyde) is one conversion step closer to retinoic acid than retinol, making it potentially more effective with less irritation.
How to Use Retinol: Your Complete Guide
Starting your retinol journey? Follow this step-by-step guide to introduce retinol safely and effectively into your routine.
Step 1: Start Low and Slow
Begin with a low concentration (0.25-0.5%) and use just twice per week initially. This allows your skin to build tolerance gradually.
Step 2: Perfect Your Application
1 Cleanse thoroughly with a gentle cleanser
2 Wait 20-30 minutes for skin to completely dry
3 Apply a pea-sized amount to your entire face (avoiding eye area)
4 Follow with moisturiser to lock in hydration
5 Always use SPF the next morning (retinol increases sun sensitivity)
Step 3: Build Your Tolerance
• Weeks 1-2: Use twice weekly
• Weeks 3-4: Increase to every other night
• Week 5+: Use nightly if skin tolerates well
Best Time to Use Retinol
Always apply retinol in the evening. UV exposure can break down retinol, making it less effective, whilst your skin naturally repairs itself overnight.
Can You Mix Retinol with Other Ingredients?
Understanding ingredient compatibility is crucial for building an effective, irritation-free routine.
SAFE TO USE WITH RETINOL:
Hyaluronic Acid - Perfect partnership! Hyaluronic acid provides essential hydration to counteract retinol's potentially drying effects. Apply hyaluronic acid serum before your moisturiser.
Niacinamide - This calming ingredient can help reduce retinol irritation. Use niacinamide in your morning routine or on non-retinol nights.
Ceramides and Peptides - Excellent for strengthening the skin barrier and supporting retinol tolerance.
USE WITH CAUTION:
Vitamin C - Can be used together but may cause irritation for sensitive skin. Best practice: use vitamin C in the morning, retinol at night.
AHA/BHA Acids - Can be combined by experienced users, but start with alternating nights. Too much exfoliation can lead to irritation and barrier damage.
AVOID MIXING:
Benzoyl Peroxide - Can deactivate retinol
High-concentration acids - Risk of over-exfoliation
