Hi! I'm 22 years old, and I have oily skin with a tendency to have acne. With this simple skincare routine, I have managed to keep my acne more or less under control (except for when I'm on my period), and I'm satisfied about it. What I want to do now is to include some active ingredients to prevent signs of ageing, but I don't know exactly what. I thought about vitamin C, but I heard it is not compatible with niacinamide and my cleanser contains it. I've seen that The Ordinary have many anti-ageing serums, so I would like to know if you recommend any of them and how to include them in my routine.
Thank you very much in advance!
