How many days should one avoid certain foods after spot treatment?

Generally, it is necessary to avoid certain foods for 7–20 days after spot treatment, with the specific duration primarily depending on the skin's healing progress. If the treated area is small and postoperative care is properly managed, dietary restrictions typically last 7–14 days. However, if the treated area is large or postoperative care is inadequate, avoidance may extend to 14–20 days. Should any discomfort occur, prompt medical consultation is advised. Detailed explanations are as follows:

If the pigmentation spots are few and scattered, skin damage during treatment tends to be relatively mild. When post-treatment care strictly follows medical advice—such as keeping the treated area clean and dry, avoiding UV exposure—the restricted diet period may last 7–14 days. In such cases, skin recovery is relatively faster, thus shortening the required dietary restriction period.

If pigmentation spots are dense and cover a wide area, skin damage during treatment is more significant. Additionally, inadequate cleansing, moisturizing, or sun protection afterward may prolong wound healing, generally requiring dietary restrictions for 14–20 days to prevent hyperpigmentation or wound infection.

During the dietary restriction period, it is recommended to maintain a light diet, avoid spicy foods, and reduce consumption of strong tea and coffee, all of which help promote skin recovery.
