Hello! I'm very new to skincare, so few days ago I posted asking for help about my routine. My main concerns were the redness of my cheeks and the fact that my T-Zone still feels slightly oily despite using a very well recommended moisturizer. Other concerns of mine were blue/purple dark circles under my eyes and big visible pores on my nose, cheeks and forehead.
I am currently following this very simple routine:
Cleanser: Cerave Hydrating Cleanser (for normal to dry skin)
Moisturizer: Cerave Facial Moisturizing Lotion (pm) (for normal to dry skin)
Sunscreen: For the face, Cerave invisible hydrating fluid sunscreen (spf 50). For the body, Cerave invisible hydrating lotion (spf 50).
I have got combination, sensitive skin. My cheeks are always some amount of red, and I've got seborrheic dermatitis mainly on my scalp (if that influences anything).
Someone recommended to me adding the The Ordinary Niacinamide 10% Zinc 1% serum after cleasing, because it helped their redness problem. It did help controlling the oiliness of my T-Zone. However, having used it a couple times, not only does it feel terribly sticky (even applied on damp skin and using moisturizer right after), but it is also making my skin burn and my cheeks even redder.
The first time it stung for a few minutes and then calmed down, even if it made my cheeks red. But after using it today it started burning, made my redness much worse, and never stopped burning. From what I've seen, Niacinamide isn't really recommended over 5% concentrations anyway, and having seen some people's skin becoming irritated or breaking out because of it online I don't think this product is for me, even if it helped with the T-Zone problem.
In addition, my cerave moisturizer already has niacinamide on it (4%, says reddit), so I'm not very sure stacking it is doing much good, which put me off from seeking another niacinamide serum and left me at a loss on what could help then. If stacking does help, do let me know!
So the question is, what can I add to my routine then instead of TO Niacinamide 10% that's not over the 25-30 euros threshold? I've spent many hours researching this morning, but I couldn't really find what would be best to help my redness and combo skin. I'd appreciate some advice, please! For reference for product recs availability, I'm from Spain
Thank you very much in advance
