What Is Acne Hyperpigmentation?

Acne hyperpigmentation (PIH) is the dark marks left behind after a pimple heals. It isn’t a scar — it’s excess pigment (melanin) that lingers on the skin surface or deeper layers.

Why It Happens

• Inflammation from acne triggers melanin overproduction
• More common in medium to darker skin tones
• Sun exposure makes marks darker
• Picking or squeezing pimples worsens pigmentation

How Hyperpigmentation Looks

• Flat or slightly raised dark brown, red-brown, or black spots
• Usually appears after acne goes away
• Can last weeks to months if untreated

How It’s Approached in Seoul, Korea

In Seoul, skincare and dermatology focus on targeted, gentle, evidence-based treatments that lighten pigment while calming acne-prone skin.

Trends include:

• Combining lightening treatments with acne-friendly routines

• Preventing sun damage with daily UV protection

Common Treatment Options

1. Topical Brighteners

◾ Vitamin C
◾ Niacinamide
◾ Licorice root extract
◾ Tranexamic acid

✔ Helps reduce melanin production
✔ Often combined with calming agents

2. Chemical Peels

◾ Mild acids like AHA, BHA
◾ Combination peels tailored to pigmentation and acne

✔ Speeds turnover of pigmented cells
✔ Must be adjusted based on sensitivity

3. Laser & Light Therapies

◾ Non-ablative lasers for pigmentation
◾ IPL (intense pulsed light)

✔ Targets deeper pigmentation
✔ Helps overall skin tone and texture

4. Prescription Creams

◾ Retinoids
◾ Hydroquinone alternatives

✔ Regulate cell turnover
✔ Should be used under professional guidance

Daily Skincare Routine Tips

Keeping a consistent routine is key to reducing acne marks.

Morning

✔ Gentle cleanser
✔ Antioxidant serum (e.g., Vitamin C)
✔ Lightweight moisturizer
✔ Daily sunscreen (SPF 30–50+)

Evening

✔ Mild cleanser
✔ Targeted serum for pigmentation
✔ Moisturizer for repair

📌 Avoid physical scrubs, harsh exfoliants, and over-stripping products.

Lifestyle & Prevention

• Avoid picking at acne — this increases pigmentation
• Sun protection year-round prevents darkening
• Keep stress, sleep, and diet balanced
• Stick with products consistently — pigmentation improves slowly

What to Expect Over Time

• Light marks: weeks to a few months
• Deep marks: several months
• Active acne control shortens overall recovery

Patience and consistency matter more than quick fixes.

Final Tips

✅ Start with gentle options before stronger treatments
✅ Introduce one active at a time
✅ Monitor irritation — adjust frequency if needed
✅ Sunscreen is non-negotiable
