[Routine Help] Replacing Niacinamide with retinol ?

Hi, here's what's been my routine for the past year:

• Novexpert Vit C foam cleanser

• Laroche-posay Effaclar duo +M

• Revox b77 Niacinamide serum

• Nivea almond milk moisturiser

I've been thinking about changing the niacinamide serum for some retinol-based serum... What do you think ?

For context, I (19M) have pretty ok skin (no bad acne but occasional pimples) and so i feel like it would be better to swap Niacinamide for something that would give my skin more elasticity/smoothness/thickness.
