หลายคนสงสัยว่าทำไม “รอยสิว” ถึงบางทีหายไว บางทีหายช้า หรือทำไมรอยแดง รอยดำ ถึงต่างกันสีก็คนละแบบ จริงๆ แล้วรอยหลังสิวมี 3 ประเภทหลักที่หลายคนมักเข้าใจผิด ได้แก่ **Dark Spot, PIH และ PIE** ซึ่ง “เกิดสาเหตุไม่เหมือนกัน” และ “ต้องรักษาคนละวิธี” แบบคนละทางเลย!

## Dark Spot คืออะไร?

![Dark Spot คืออะไร](https://wiseplusgrow.com/wp-content/uploads/2025/11/dark-spot-melanin-pigmentation.jpg)

Dark Spot คือ “จุดด่างดำที่เกิดจากเม็ดสีเมลานินเกินปกติ” เกิดจากแดด อายุ และฮอร์โมน ไม่ได้เกี่ยวกับสิวโดยตรง

### ลักษณะเด่น

- สีน้ำตาลอ่อน–เข้ม
- ขอบชัด
- เกิดบนบริเวณโดนแดด เช่น แก้ม หน้าผาก

### สาเหตุหลัก

- แดด (UV)
- อายุ (Aging)
- ฮอร์โมน

### วิธีรักษา

- Vitamin C
- Alpha Arbutin
- Kojic Acid
- Niacinamide
- Retinol / Retinal
- กันแดด SPF 50 ทุกวัน

## PIH คืออะไร?

![pih-รอยดำหลังสิว](https://wiseplusgrow.com/wp-content/uploads/2025/11/post-inflammatory-hyperpigmentation-pih.jpg)

**PIH = Post Inflammatory Hyperpigmentation **คือ “รอยดำหลังสิว” ที่เกิดจากการอักเสบทำให้เมลานินเพิ่มขึ้น

### ลักษณะเด่น

- สีน้ำตาลเข้ม–ม่วง
- เกิดหลังสิวหาย
- กดไม่จาง

### สาเหตุ

- สิวอักเสบ
- แกะสิว
- เลเซอร์/ผลัดผิวเกินความจำเป็น

### วิธีรักษาเฉพาะแบบเมลานิน

- Retinoid (Retinol/Retinal/Adapalene)
- Vitamin C
- Tranexamic Acid
- Niacinamide
- AHA/BHA ผลัดเบา

**PIH ต้องใช้เวลา 2–3 เดือนกว่าจะจาง**

## PIE คืออะไร?

![pie-รอยแดงหลังสิว](https://wiseplusgrow.com/wp-content/uploads/2025/11/post-inflammatory-erythema-pie.jpg)

**PIE = Post Inflammatory Erythema **คือ “รอยแดงหลังสิว” เกิดจากเส้นเลือดขยายตัว ไม่ใช่เม็ดสี

### ลักษณะเด่น

- สีแดง–ชมพู
- มักเกิดหลังสิวอักเสบลึก
- กดแล้วซีด → แสดงว่าเป็นเส้นเลือด

### สาเหตุ

- การอักเสบของผิว
- เกราะผิวเสีย
- ผิวบางจากสครับ/กรดแรง

### วิธีรักษาเฉพาะเส้นเลือด

- Cica / Madecassoside
- Panthenol
- Azelaic Acid 10–20%
- Redness serum
- ห้ามผลัดเซลล์แรง
- เลเซอร์ V-beam / IPL (ได้ผลที่สุด)

## ตารางเปรียบเทียบ Dark Spot vs PIH vs PIE

ประเภท
สี
สาเหตุ
ตำแหน่ง
วิธีรักษา

Dark Spot
น้ำตาลเข้ม
แดด/อายุ
โหนกแก้ม หน้าผาก
Vitamin C, Retinol, กันแดด

PIH
น้ำตาล–ม่วง
รอยหลังสิว (เมลานิน)
บริเวณที่มีสิว
Retinoid, Vitamin C, AHA

PIE
แดง–ชมพู
เส้นเลือดจากการอักเสบ
ทุกจุดที่เป็นสิวอักเสบ
Cica, Azelaic, เลเซอร์เส้นเลือด

## ถ้ารักษาผิดวิธีจะเกิดอะไรขึ้น?

- ทาไวท์เทนนิ่งกับ PIE → ไม่หายเพราะไม่ใช่เม็ดสี
- ผลัดผิวแรงใน PIE → แดงหนักกว่าเดิม
- ทาแต่อ่อนโยนกับ PIH → จางช้ามาก
- ไม่ทากันแดดใน Dark Spot → เข้มขึ้นเรื่อย ๆ

## สรุปง่ายที่สุด

- **Dark Spot = จุดแดด/จุดอายุ (เมลานิน)**
- **PIH = รอยดำหลังสิว (เมลานิน)**
- **PIE = รอยแดงหลังสิว (เส้นเลือด)**

ถ้ารู้ว่าเป็นแบบไหน → รักษาได้เร็วขึ้น 2–3 เท่า

## คำถามที่พบบ่อย

### PIH จะหายเองไหม?

ส่วนใหญ่หายเองได้ แต่ใช้เวลา 3–6 เดือน ถ้าใช้ Active จะหายเร็วขึ้น

### PIE ต้องใช้ไวท์เทนนิ่งไหม?

ไม่จำเป็น และไม่ค่อยช่วย เพราะ PIE เกี่ยวกับเส้นเลือดไม่ใช่เม็ดสี

### ทุกคนเป็นรอยแดงก่อน แล้วค่อยเป็นรอยดำไหม?

ไม่จำเป็น อยู่ที่ความรุนแรงของสิวและการอักเสบของผิว

### เลเซอร์ V-beam สำหรับ PIE เจ็บไหม?

เจ็บเล็กน้อย แต่ได้ผลไวที่สุดในรอยแดงหลังสิว

### ต้องใช้กันแดดกับทั้ง 3 ประเภทไหม?

ต้องใช้ เพราะ UV ทำให้รอยทุกแบบเข้มขึ้น และฟื้นตัวช้ากว่าเดิม
