What can I put on my face now to slow the process of aging? (23 yrs old)

Hi! I am 23 years old and I currently have no skincare routine besides washing my face morning and night with cerave face wash.  I keep reading about all these retinoids and vitamin c etc. and it’s all very confusing and I just wanted to know if there’s any type of cream I should be putting on my face/around my eyes at night or anything else to help with aging in the future? Is there a specific brand anyone recommends? (I have very sensitive skin and my eyes got completely swollen even with the cerave under eye cream)
