I have these pores on my nose that made it look bigger in size than the normal plus the pores are visible what should I do? It keep my self esteem low

Cold water… after washing your face with soap and warm water and gently scrubbing, dry your face and then use witch hazel on some cotton make up remover pads to clean your nose. Then wash your face, concentrating on your nose in particular, with cold or even icy cold water, if you can tolerate it. This will close the pores. Self-esteem is an issue for everybody. Good luck with conquering your fears…
