Must-read before booking: Important notes

- Post-treatment recovery: After hyaluronic acid injections, keep the area moisturized and protected from the sun. After laser treatments, there may be mild redness (which subsides within 1–3 days); it is recommended to schedule travel for the day after the treatment.
- Fee confirmation: After the in-person consultation, the director will provide a clear quote, and the treatment will only proceed after it is confirmed on the spot, with no hidden fees.
