There is no easy solution for bad skin, even when you have all the resources in the world. For these celebrities, who are constantly photographed the scrutiny is even greater. The good news is, most have improved while some have found other ways to cover up their unwanted blemishes.
Here are a few easy things you can do to keep your skin looking healthy and glowing:
- Drink plenty of water. Many recommend drinking eight glasses of water a day!
- Always wear SPF. The suns rays are powerful and without proper protection can dry out your skin.
- Wash your face twice a day. Get a fresh start to your day by giving it a good wash but remember to do the same in the evening (your skin collects a lot of dirt). You may not have realized that washing your face twice a day was this important, click here for other skin care tips you've never heard of!
