"Lip lines" can be treated with topical retinoids, hydrating lip products with SPF, and in-office procedures like laser resurfacing or fillers to smooth vertical lines.
The neck is often exposed to UV rays during driving, outdoor activities, or wearing low-cut tops. Cumulative sun exposure causes photoaging, leading to wrinkles, sunspots, and loss of firmness.
Sleeping on your side or stomach can cause creases and "sleep lines" on the neck. Try to sleep on your back, and use a silk or satin pillowcase to reduce friction.
Daily sunscreen application is the most critical habit. Combined with extending your facial anti-aging routine to your neck, this provides comprehensive protection and care.
