Hello..Thanks for your query
As for regular care of skin ,you should use a sensitive mild cleanser.
Try to use a Retinoid
topically at night.
Orally you should have supplements containing Vit C and Vit E to reduce the free radical induced damage to body and prevent aging changes.Y
ou also should apply non comedogenic moisturizers containing Vit A and E in the morning.It is very important to avoid sun exposure and apply a broad spectrum sunscreen when you go out.
For the open pores, they may develop due to loss of collagen
in the aging process.You can consult a dermatologist
for lasers for photorejuvination of skin.
Hope this helps.Take care.
