## Choosing a Sunscreen with a Low SPF
The SPF value indicates the level of protection against UVB rays. For effective protection, opt for products with an SPF of 30 or higher. If you have sensitive skin or plan on prolonged sun exposure, consider using a sunscreen with an even higher SPF.

## Applying Insufficient Amounts of Sunscreen
Many people apply a thin layer of sunscreen, which is often inadequate for effective protection. Ensure you apply enough sunscreen to create a protective barrier on your skin. It is recommended to use approximately 2mg of sunscreen per cm² of skin.
## Not Reapplying Sunscreen Throughout the Day
The notion that applying sunscreen once in the morning is sufficient for the entire day is incorrect. Sunscreen loses its effectiveness over time, especially if you sweat profusely or come into contact with water. For optimal protection, reapply sunscreen every 2-3 hours.

## Neglecting Additional Sun Protection Measures
UV rays can penetrate through sunscreen if no supplementary protective measures are taken. Shielding your skin from the sun with physical barriers helps minimize its impact, preventing skin darkening and aging.
## Inadequate Skin Cleansing Before Sunscreen Application
Many individuals only rinse their faces without properly addressing dirt and oil buildup. If the skin is not thoroughly cleansed, sunscreen may not reach its full potential. Ensure your skin is thoroughly cleansed before applying sunscreen, as dirt can reduce its protective capabilities.
UV rays can affect your skin at any time, even when you’re indoors. As a fundamental step in your skincare routine, apply sunscreen after your serum and moisturizer. Choose a sunscreen with an SPF of 30 or higher to ensure optimal protection.
While sunscreen is an essential part of your daily skincare routine, committing these mistakes can render even the most expensive sunscreen ineffective in maintaining healthy and radiant skin.
