Yes, Tretin 0.025% Cream may help improve the appearance of open pores, even if you do not have active acne (pimples). It contains tretinoin, which helps renew skin cells and improve skin texture over time, making pores appear less noticeable. However, it will not permanently shrink the pores. Tretinoin can cause dryness, redness, peeling, and irritation, especially when you first start using it. For this reason, avoid applying it every day at the beginning. Start by applying a small amount two or three nights a week, then gradually increase the frequency if your skin tolerates it well. Some people can use it daily, but only after their skin has adjusted and preferably under the guidance of a dermatologist. Use a moisturiser regularly and apply sunscreen every morning, as tretinoin can make your skin more sensitive to sunlight.
