As a skin professional, I see many teens with advanced skin issues such as acne and scarring.  If you introduce your tween to a good skin care program before they hit the teen issues, they can have good skin for the rest of their life. 

By the age of 10 or 11, tweens are asserting their independence and developing their own sense of style.  This is the perfect time for them to be responsible and also learn that they are worth the time it takes to pamper and take care of themselves. 

At this point, tween skin does not require much.  It is important they cleanse skin twice a day with a gentle cleanser followed by a light, oil free moisturizer.  An SPF 15-30 should be used daily to protect against sun damage. 

You need to let them show you what they want so they will be excited to use it-thus developing good habits early.  You also have to make sure their choices are appropriate for young skin.  They should avoid anti-aging, acid, and grainy scrub type products.  They don’t need these ingredients and some may be too harsh.  Using fragrance free products will help reduce allergic reactions. 

You already know that tweens need constant and gentle reminders for most tasks.  This is likely to be no different.  But preserving their soft, smooth and radiant skin will be worth it.
