Laser pore reduction is not permanent. Some people with large pores can improve the follicular pores on the surface of the skin through laser treatment, thus making the skin look smoother and more delicate, but this treatment is not permanent. A course of laser pore reduction can last about 1 year, and its specific maintenance time has some correlation with individual differences, age, type of laser, parameters, etc. If the root cause of enlarged pores is not lifted, enlarged pores will gradually form even after laser treatment. The main reason for the formation of this condition is the patient’s high sebum secretion or persistent acne, as well as some common skin diseases such as seborrheic dermatitis, so it is recommended that the primary disease still needs to be treated at the root. As mentioned above, although the effect of laser pore reduction is relatively good, but after the treatment, candidates also need to do a good job of related care work. In addition, as an inevitable result of skin aging, enlarged pores can only be delayed and cannot be reversed permanently, and the skin will still produce enlarged pores over time. Therefore, it is recommended that you must pay attention to the care work, usually drink more water, eat more fruits and vegetables rich in vitamin C, and pay attention to daily sun protection.
