The Sandwich Technique & Understanding Vitamin A Derivatives
Retinoids — derivatives of Vitamin A — are some of the most powerful ingredients in skincare. They:
- Smooth fine lines
- Improve skin texture and tone
- Reduce hyperpigmentation
- Treat acne
- Stimulate collagen production
But with power comes responsibility. Used incorrectly, retinoids can cause irritation, dryness, and redness — especially for beginners.
Fortunately, there’s a dermatologist-approved way to enjoy all the benefits without harming your skin barrier. Enter the Sandwich Technique, popularized by board-certified dermatologist Dr. Tamara Lazic, who champions gentle, effective routines for active ingredients.
🥪 What Is the Sandwich Technique?
The Sandwich Technique involves buffering your retinoid with moisturizer — before and after application — like a skincare sandwich. This method:
✅ Reduces irritation
✅ Protects the skin barrier
✅ Helps your skin adjust more gently
🔄 Step-by-Step:
- Cleanse with a gentle, non-foaming cleanser and pat dry.
- Apply a thin layer of moisturizer to slightly damp skin.
- Wait 1–2 minutes, then apply a pea-sized amount of retinoid to your face (avoid eyes and mouth).
- Finish with another layer of moisturizer to lock in hydration.
🧴 Dr. Tamara Lazic recommends this method especially for sensitive, dry, or reactive skin, as it reduces the harsh “retinization” phase.
⚖️ Start Slow and Stay Consistent
- Begin with 2–3 times per week — especially if using potent forms like retinal or tretinoin
- After 2–4 weeks, you can slowly increase frequency to every other night or nightly
- Avoid mixing with exfoliating acids (like AHAs or BHAs) on the same night
- Use SPF 50+ daily — retinoids increase UV sensitivity
🧬 Understanding the Different Types of Retinoids
Not all Vitamin A derivatives are equal. They differ in strength, speed, and irritation potential. Here’s a breakdown:
1. Tretinoin (Retinoic Acid)
- Prescription-only
- Works immediately without conversion
- Strongest, fastest results
- Higher risk of irritation — great for advanced users
- Use the sandwich method and go slow
2. Retinaldehyde (Retinal)
- Converts to retinoic acid in 1 step
- More potent than retinol, gentler than tretinoin
- Great for intermediate users
3. Retinol
- Most popular over-the-counter form
- Converts in 2 steps
- Effective for most skin types
- Ideal for beginners
4. Retinyl Esters (e.g., Retinyl Palmitate)
- Weakest form (converts in 3 steps)
- Best for ultra-sensitive skin
- Minimal irritation, slower results
5. Bakuchiol (Retinol Alternative)
- Plant-based, non-irritating
- Safe during pregnancy
- Retinol-like effects without the side effects
- Still emerging in research but promising
⏳ When Will You See Results?
- Glow + smoother texture: 4–6 weeks
- Fine lines + pigmentation reduction: 8–12 weeks
- Firmness + collagen increase: 3–6 months
Consistency is everything. Think of retinoids as a long-term investment for your skin — gentle and steady wins the race.
✨ Final Thoughts
Retinoids are a cornerstone of modern skincare — if used wisely.
Dr. Tamara Lazic’s Sandwich Technique offers a practical, skin-friendly way to harness their benefits while avoiding irritation. Whether you’re using retinol, retinal, or tretinoin, remember:
- Start slow
- Buffer with moisturizer

Your skin doesn’t have to suffer to improve.
