Can I eat soy sauce after getting double eyelid surgery?

There is no need to deliberately avoid soy sauce after double eyelid surgery. This condiment, made from fermented soybeans and wheat, contains pigment molecules that are broken down in the intestines and cannot reach the surgical incision via the bloodstream, let alone deposit locally.

To date, no clinical studies have confirmed that dark-colored sauces worsen scar pigmentation. On the contrary, the amino acids and trace elements in soy sauce can provide raw materials for collagen synthesis, which benefits tissue repair; simply controlling total intake to prevent excessive sodium consumption is sufficient.

The quality of incision healing primarily depends on sterile technique, local wound care, and individual constitution. Keeping the wound clean and dry, applying topical antimicrobial ointments as prescribed, and avoiding eye rubbing or premature exposure to water are far more effective in reducing risks of hyperpigmentation and hypertrophic scarring than restricting condiments.

The postoperative dietary principle emphasizes high protein, high vitamins, and moderate caloric intake. Eggs, fish, poultry, lean meat, dairy products, and fresh fruits and vegetables are recommended to support collagen regeneration and epithelialization. If persistent redness, discharge, or increasing pain occurs, timely follow-up evaluation is necessary rather than attributing symptoms to common seasonings.

In short, soy sauce can be used as usual—balanced nutrition and proper wound care are the true cornerstones of postoperative recovery.
