Original title: 선크림은 바르고 있는데 광노화가 생기는 이유

Main Summary
Even when sunscreen is applied daily, skin elasticity concerns or pigmentation issues can still emerge over time. This may not be a problem with the sunscreen itself, but rather with how it is being used.
To make the most of sunscreen's UV protection, applying a sufficient amount and reapplying at appropriate intervals during the day are both important. UVA can also reach the skin on cloudy days and indoors — so building a consistent daily habit, rather than only applying on sunny days, is key.
DR.COHEN frames sun care not just as product use but as a proper routine. Hyalu Cica Watery Sun Serum is designed to be used as the last step of the morning skincare routine, with reapplication when needed, as part of a consistent daily sun care habit.
DR.COHEN's Perspective
DR.COHEN treats sun care as a routine that considers not just product selection, but also application amount, timing, and reapplication habits.
Applying a sufficient amount as the final step of the morning skincare routine — and reapplying every 2–3 hours during outdoor activities — can help maintain UV protection throughout the day. DR.COHEN Hyalu Cica Watery Sun Serum is designed with a light, hydrating feel to make this kind of daily routine easy to maintain.
DR.COHEN's sun care routine philosophy follows this flow: correct application amount → daily use → reapplication when needed → long-term skin condition management.

FAQ
Q. Why am I experiencing photoaging even though I apply sunscreen daily?
A. The effectiveness of sunscreen depends on both the amount applied and how it is used. Applying a sufficient amount and reapplying during the day are important factors in making the most of its UV protection.
Q. When in my routine should I apply sunscreen?
A. Sunscreen is best applied as the last step of the morning skincare routine. Apply it after your skincare products have been absorbed, then head out.

A. During outdoor activities, reapplying every 2–3 hours can be helpful. Even on days spent mostly indoors, applying once in the morning as part of your daily routine is recommended.
Expression Cautions
- ⚠Avoid stating 'not wearing sunscreen will definitely cause photoaging' — use 'cumulative UV exposure may contribute to skin condition decline over time.'
- ⚠Do not claim 'SPF50+ provides complete protection' — state 'provides SPF50+ PA++++ UV protection' instead.
- ⚠Rather than 'reapplication is required or sunscreen has no effect,' use 'reapplication can help maintain UV protection more consistently throughout the day.'
