Are there any essences or serums that help with skin regeneration?

As I get older, I often feel that my skin's regeneration speed has slowed down significantly compared to the past. My skin barrier seems to be thinning, and concerns such as enlarged pores, elasticity, and blemishes are gradually increasing. Since my skin is quite sensitive, I prefer daily home care over visiting a dermatologist. Are there any basic skincare products or methods that could help with skin regeneration? If there is a lightweight serum or essence, I would like to use it consistently. I hope that skin regeneration is something that can be improved with consistent care. Please recommend any good products you know of.
