2. After the procedure, **mild swelling or redness** may occur and usually subsides within a few hours, but in some cases may last 2–3 days.

3. After the procedure, you must **apply sunscreen when going outdoors.

4. Using soothing, moisturizing, and brightening masks or packs regularly, or receiving whitening care, can help enhance the treatment results.

5. The treated area may sometimes feel itchy or dry, but this is a normal part of the healing process. Be sure to use moisturizers and regenerative creams generously, and avoid scrubbing or harsh cleansing.

6. Since the treatment targets deeper skin layers, it may occasionally stimulate sebaceous glands, causing acne-like breakouts. If this occurs, please visit the clinic for proper evaluation and treatment guidance,
