Can 50+ Sun Block Cause Premature Wrinkling?

HI!



i have a question about a sun block. I've been using eucerin 50+ for about 3 years. almost every day when i go out. Now i am afraid ill damaged my skin and that sun block ingredients its to heavy for my facial skin and that this might cause premature aging. I've been using sun bloc because i want to be fully protected from the sun and its damaging effect. Can this 50+ sun block cause premature wrinkling?

Hello. Thanks for writing to us at healthcaremagic

Contrary to what you believe, a broad spectrum sunscreen is rather protective against sun induced damage (photoageing) and delays the onset of fine lines and wrinkles.
Photoageing is characterized by gradually diminishing collagen and elastin from the dermis due to the effect of the UV A induced reactive oxygen species (ROS) which damage dermal collagen and elastin.
UV A part of the electromagnetic spectrum is mainly responsible for photoageing.
A broad spectrum sunscreen (spf 30 and more) filters both UV B as well as UV A part of the electromagnetic spectrum and is therefore protective. Therefore, you may continue with the sunscreen for its protective effects against photoageing.
To be effective a sunscreen should be applied every 2-3 hours and in adequate amounts on the sun-exposed skin, specially when moving outdoors.
A sunscreen should be applied 15-20 mins before stepping out in the sun to be fully effective.
