Yes, you can use tretinoin and retinol together, although it's important to note that retinol is usually the preferred option for beginners due to its milder formulation, which is less likely to cause irritation. When combining tretinoin and retinol, you should apply retinol first, allowing it to penetrate the skin without being diluted by retinoin. This is because retinol is more easily inactivated by sunlight, whereas retinoin can penetrate the skin without the need for retinization.
