Understanding Fading vs. Complete Removal
According to Dr. Nishant Jain, MBBS, DDVL, sunspots (solar lentigines) and freckles (ephelides) result from UV-induced melanin overproduction. Ephelides are typically 1-2mm and may fade naturally in winter, whereas solar lentigines are permanent structural changes common after age 40. Topicals fade these marks by inhibiting the tyrosinase enzyme (which converts tyrosine to melanin), but they cannot erase them completely.
For complete removal, Dr. Kiran Sethi, Dermatologist notes that clinical procedures are required. PicoSure lasers take 3-6 sessions to clear stubborn sunspots while minimizing post-inflammatory hyperpigmentation (PIH) risks in Indian skin, and electrocautery can remove individual spots in a single 50-minute session.
The Correct Winter Application Protocol
To stop flakiness while targeting pigmentation, stop layering these actives simultaneously. Follow this split-routine protocol:
- AM Routine (Brightening & Prevention): Apply a clinical D2C 2% alpha arbutin serum on cleansed, dry skin. Alpha arbutin acts on the tyrosinase enzyme without increasing photosensitivity. Follow with a ceramide-based moisturizer.
- AM Sun Protection: A 12-week clinical study on 216 participants with Indian skin types IV and V published in the IJDVL demonstrated a statistically significant reduction (P < 0.001) in pigmented spot density when using SPF 50, PA+++ twice daily. Apply two fingers of sunscreen 20 minutes before exposure.
- PM Routine (Cell Turnover & Repair): Use the "sandwich method" for retinol. Apply a hyaluronic acid serum on damp skin to draw in moisture. Wait 2 minutes until dry, apply a pea-sized amount of 0.1% to 0.3% retinol serum, and immediately seal with a thick ceramide moisturizer to prevent overnight moisture loss.
Contraindications for Indian Skin
Dr. Divya Sharma, Dermatologist warns against using DIY home remedies like lemon juice or raw turmeric on sunspots. These highly acidic and unregulated ingredients cause severe irritation, leading to post-inflammatory hyperpigmentation (PIH) in melanin-rich Indian skin. Stick to clinically formulated actives and avoid introducing exfoliating acids (like glycolic acid or salicylic acid) on the same nights you apply retinol.
