Disease description:

I am a 30-year-old woman who recently received laser skin treatment, primarily to improve pigmentation spots and acne marks on my face. After the treatment, my doctor informed me about some post-treatment care instructions, but I still have some concerns. Could you please tell me what are the main aftercare considerations following laser skin treatment?

After skin laser treatment, main points of attention include protecting the skin, avoiding irritation, maintaining cleanliness, and promoting healing. Following laser therapy, the skin will be in a relatively fragile state and is more susceptible to external environmental influences. Therefore, special attention should be given to post-treatment care in order to promote skin recovery and reduce the occurrence of complications. The skin after laser treatment may exhibit redness, pain, or mild exudation, which are normal reactions and typically subside gradually within a few days.

It is recommended to keep the treated area clean and avoid touching or scratching it with hands to prevent infection. Use skincare products recommended by your physician, especially those with soothing and moisturizing effects, to help alleviate discomfort. Avoid using skincare products containing irritating ingredients such as alcohol or fruit acids, as these may increase skin sensitivity. Before the skin has fully recovered, avoid exposure to sunlight; when going outdoors, apply a high SPF sunscreen, wear a hat, or use an umbrella to protect the skin from UV damage. If severe discomfort or abnormal conditions occur, contact your doctor promptly.
