2. 主な用途:
- ひふ: 主に皮膚の引き締めに使用されます, たるんだ部分を持ち上げる (like jowls, ネック, and cheeks), and reducing the appearance of wrinkles. It penetrates deeper into the skin compared to many other non-invasive treatments.

3. 治療の深さ:
- ひふ: Penetrates deeply into the skin, 真皮深部と表層筋腱膜系を標的とする (SMAS), which makes it effective for facial contouring and lifting.

4. 痛みと不快感:

5. 回復時間:
- ひふ: Minimal to no downtime, though there may be some mild swelling or redness immediately after treatment.

6. 効果:

- LED PDT: Effective for treating acne, reducing redness, and rejuvenating the skin’s appearance, but it doesn’t provide the same lifting effects as HIFU.
7. 必要なセッション:
- ひふ: Often requires just 1-2 sessions for noticeable results, with maintenance sessions every 6-12 月.
- LED PDT: Typically requires multiple sessions (weekly or biweekly) for best results, depending on the condition being treated.

9. 副作用:
- ひふ: Possible side effects include mild swelling, bruising, and temporary redness.
- LED PDT: 最小限の副作用, but some patients may experience slight redness or sensitivity following treatment.
