Q Will skin tanned by summer UV rays recover on its own in autumn?
A Sunburn redness subsides as the epidermis regenerates within 2–3 weeks, but UV-induced pigmentation and collagen damage do not fully recover on their own. Strict sun protection combined with antioxidant care such as Vitamin C is needed to accelerate pigmentation improvement. The more damage accumulates, the harder recovery becomes, making prevention most important.
Detailed Answer
UV damage occurs in two stages. ①Immediate reaction: temporary darkening from melanin oxidation (recovers within days). ②Delayed reaction: pigmentation from new melanin synthesis (lasts weeks to months). Collagen degradation accumulates over years, appearing as wrinkles and loss of elasticity. Continue using SPF30+ sunscreen in autumn and winter, and use Vitamin C (brightening) and niacinamide to aid pigmentation improvement.
Korean Medicine Clinic Perspective
Korean medicine diagnoses post-summer UV pigmentation as Blood-Stasis (血瘀) and Liver Spots (肝斑). Applying blood-activating, stasis-resolving (活血化瘀) herbs such as Peach kernel (桃仁), Safflower (紅花), Motherwort (益母草), and Mulberry root bark (桑白皮), combined with sun protection, is effective for pigmentation improvement. Dongjedang runs a post-summer skin recovery intensive program.
