At that age your lines might be the results of lacking of hydration or just simply bad lifestyle. Drinking enough is vital for your whole system not just for your skin! Retinol is awesome but it’s not for everyone, folks that develop allergy reaction to it cannot use retinol, I wouldn’t recommend bakuchiol either, the research behind it is just not enough to support a significant results on skin.
I would suggest to have a chat with a derm before you jump to products. Meanwhile, make sure your routine has products that can help maintain hydration.
If there’s doubt on using retinol, better patch test it first since you have sensitive skin. I will drop one very gentle retinol product (Sweet Chef) for you and some hydrating products. Hope this helps.
