Hello,
Dark circles caused by retinization (retinoid irritation) and sun exposure are usually due to post-inflammatory hyperpigmentation and skin barrier damage in the under-eye area. The under-eye skin is very thin and sensitive, so overuse of retinoids or sun exposure can increase pigmentation.
The first step is to allow the skin barrier to recover before starting any active treatment.
Suggesting you few things which you should start doing~
✔ Step 1: Stop irritation
• Pause retinoid use around the under-eye area
• Use a gentle moisturizer (barrier-repair type)
• Avoid rubbing or exfoliating
✔ Step 2: Strict sun protection
• Broad-spectrum sunscreen SPF 50 daily
• Reapply if outdoors
• Sunglasses when outside
✔ Step 3: Pigmentation control (after irritation settles)
• Mild
Vitamin C-based eye serum
• Niacinamide-containing cream
• Avoid strong bleaching agents without supervision
Improvement is gradual ..usually visible over 6–8 weeks.
NOTE: If pigmentation is:
• Genetic
• Due to thin skin showing blood vessels
• Due to chronic allergies
Then treatment approach differs.
So correct diagnosis is important before starting strong creams.
Next Steps
If pigmentation persists despite sun protection and barrier repair, a detailed skin evaluation can help determine whether it is inflammatory, vascular, or genetic in origin.
