Most important thing - keep using a sunscreen daily! 🙌
Overall, you might want to aim to use both the retinol oil and the azelaic acid product more frequently - every other day and even every day eventually (don't increase the frequency straight away but move gradually).
You probably can stop the Caffeine + EGCG solution without losing any long-term benefits for your skin - in case you'd like to simplify your routine a bit.
Overall, your routine is looking good - especially if you are not bothered by fragrance and your skin isn't particularly sensitive.
Hello Maria and thanks for your advice!
You are right, the caffeine + EGCG solution is not really improving my dark circles although I use it every day and for two months now I would say. I am going to check on this site other products that might be more effective.
I use every day sunscreen but this week I will receive one by Cosrx that I feel will be better for my skin.
I am using Nivea (German version) only after I use Retinol.
Thank you again for all your comments!
Unfortunately, no skincare product can really help with dark circles unless they are caused by actual darker pigmentation in this area (which is not the case for most people). Concealer & sleep is the only effective course of action...
