Are niacinamide and panthenol ingredients okay for sensitive skin?

My skin has become sensitive lately, so I tend to carefully check the ingredients whenever I use new cosmetics.

I recently purchased the Tone28 Niacinamide product after receiving a recommendation,

I am wondering if it can be used without any issues even on sensitive skin. I would like to hear reviews from those who have used it.

My skin barrier tends to be weak; did you experience any irritation such as stinging or redness?

I am wondering if you experienced any skin trouble. Also, when I first started using it, is it okay to apply it every day?

Or I would like to know if it would be good to start with about 2 to 3 times a week.

If you have used this on dry, sensitive, or combination sensitive skin, please share your experiences or usage tips. Thank you.
