Why Retinol Is a Game-Changer (and Why Application Matters)
Retinol is widely recognized as one of the most effective ingredients for anti-aging, skin renewal, and collagen production. However, using it incorrectly can lead to irritation, excessive dryness, and reduced effectiveness. Many people struggle with knowing exactly when and how to apply retinol in their routine. Should it go before or after moisturizer? Does layering impact its effectiveness? Let’s talk about it.
Where Retinol Fits in Your Daily Routine
Instead of thinking about separate morning and evening routines, it helps to view your skincare steps as a continuous, daily cycle that supports your skin around the clock.
Morning Steps (Protect & Maintain Your Skin Barrier)
- Cleanse (If Needed) – Some may prefer a water rinse in the morning instead of a full cleanse.
- Toner/Serum – Apply any morning-appropriate serums, such as hydrating ingredients or antioxidants.
- Moisturizer – Reinforce hydration and barrier protection.
- Sunscreen – This is non-negotiable! Retinol increases sun sensitivity, so SPF 30+ is a must every morning.
Evening Steps (Preparing Skin for Repair & Renewal)
- Cleanse – Start with a gentle, hydrating cleanser to remove dirt and prep your skin.
- Toner (Optional) – Hydrating toners can be applied before retinol, but avoid exfoliating or alcohol-based formulas.
- Serum (If Applicable) – If using hydrating serums (like hyaluronic acid), apply them before retinol.
- Retinol – Apply a pea-sized amount to dry skin.
- Moisturizer – Use a soothing moisturizer to lock in hydration and buffer irritation.
🔹 Pro Tip: If retinol makes your skin dry or irritated, try the sandwich method – apply a thin layer of moisturizer before and after retinol to create a barrier that reduces irritation.
Common Retinol Mistakes & How to Avoid Them
Even experienced skin care users make mistakes with retinol. Here are the most common errors and how to fix them:
❌ Applying Retinol to Damp Skin → Always apply to completely dry skin to prevent deeper penetration that could cause irritation.
❌ Using Too Much → A pea-sized amount is enough for the entire face. Overuse leads to peeling and sensitivity.
❌ Mixing Retinol with the Wrong Ingredients → Be mindful when combining retinol with Vitamin C. Some forms of Vitamin C (such as L-ascorbic acid) can be too harsh when paired with retinol, while others (like tetrahexyldecyl ascorbate) are gentler and can be used together. If you're unsure, apply Vitamin C in the morning and retinol at night.
❌ Skipping Sunscreen → Retinol makes your skin more sensitive to UV damage, so SPF must be applied every morning.
❌ Giving Up Too Soon → Retinol has an adjustment period of 4-6 weeks. Mild dryness or flaking is normal initially, but consistent use will bring smoother, brighter skin.
Expert Tip: Catherine’s Recommendation for Better Retinol Results
To get the most out of retinol while minimizing irritation, I suggests pairing retinol with a barrier-repairing moisturizer that includes ceramides, peptides, or niacinamide. These ingredients help maintain a strong skin barrier, reducing the risk of flaking and redness.
I also advise clients to introduce retinol gradually beginning with 1-2x per week for a minimum of 4-6 weeks and slowly increasing from there. Also, avoid harsh exfoliation on the same nights they use retinol.
Final Thoughts: Simple Takeaways for Better Retinol Use
✔ Apply retinol at night to dry skin, followed by moisturizer.
✔ Use hydrating and antioxidant-rich products in the morning to support skin renewal.
✔ Start slowly and increase frequency as your skin adapts.
✔ Be mindful when pairing Vitamin C and retinol – some forms can be used together, while others should be separated.
✔ Always wear sunscreen in the morning.
✔ Use a barrier-supporting moisturizer to prevent irritation.
