Retinoic acid cream does not aggravate enlarged pores. Vitamin A cream mainly treats common acne such as blackheads, acne, skin lesions, ichthyosis, follicular keratosis, psoriasis, mucous membrane leukoplakia, and skin diseases such as hyperpigmentation. When using it for the first time, apply it on the inside of the arm and behind the ear to check for any allergic symptoms, and use it only if there is no discomfort. In addition, it is worth noting that Vitamin A cream may cause symptoms of skin irritation, erythema and flaking when applied topically, so you can observe the situation first. If the drug continues to worsen, it is necessary to intermittently use the drug or stop it under the guidance of a doctor. You should try to avoid sunlight or shade when using retinoic acid cream to reduce the decomposition of the drug by ultraviolet light. When using retinoic acid cream at bedtime, apply the cream gently to the affected area. If on the face, it needs to be cleaned well in advance, while taking care to avoid the eyes and folds of the skin. If enlarged pores exist during the application of retinoic acid cream, they may be caused by overproduction of sebum. You should strengthen skin management, pay attention to clean skin, ensure regular rest and rest, and if necessary, you can also use fractional laser or other methods to make the pores smaller.
