My skin is sensitive and dry, and the area around my mouth is really chapped.

Lately, I keep getting redness and small breakouts around my chin and mouth. Why is this happening? It gets worse during my period... The bumps are small and millet-like, and my skin texture feels rougher than before. I feel like my skin has suddenly become sensitive. I'm wondering if the cosmetics I've been using don't agree with me, or if my skin has been irritated by masks or cleansing. I have been wearing a lot of masks lately because of a sore throat! My basic skincare routine hasn't changed, but actually, it's difficult to focus on moisturizing.

I'm using two basic products!!

I also feel dryness. How should I manage this?
