The Science Behind S C I E N C E + Retinol 1 %
By Ashlee Smith, Medical Aesthetics Nurse & Founder of S C I E N C E +
Our Retinol 1 % Serum was developed with medical-grade precision to deliver maximum efficacy with minimal irritation. Formulated with pure 1 % retinol, hyaluronic acid, and peptides, this treatment works overnight to renew, smooth, and strengthen the skin barrier.
Unlike traditional retinol formulas that can cause dryness or flaking, our advanced delivery system ensures a gradual, controlled release — so your skin reaps the benefits without unnecessary sensitivity.
We’ve also infused the formula with antioxidants and soothing botanicals to help calm inflammation and support hydration, leaving your skin balanced and refreshed by morning.
How to Use Retinol Correctly
Retinol is best introduced gradually into your nighttime routine. Start slow and let your skin build tolerance over time.
Evening Routine:
1. Cleanse with Hydrating Cleanser + or Exfoliating Cleanser +
2. Tone with Pro Toner + to prep and rebalance
3. Apply Retinol 1 % Serum (2–3 nights per week to start)
4. Moisturize with Pro Factor 5 Night Cream or Overnight Collagen + Mask to lock in hydration
Pro Tip: Avoid layering retinol with Vitamin C in the same routine. Use Vitamin C in the morning for antioxidant protection, and Retinol at night for cell renewal.

“Retinol is a true skin transformer when used correctly. Start slow, stay consistent, and always protect your skin with SPF during the day. The results — smoother, firmer, more luminous skin — are worth the commitment.”
— Ashlee Smith, Founder of S C I E N C E +
