Launched in 2009 and one of our Best of 2009 beauty products, Define targets the lip area. It was developed by Your Best Face with feedback from Truth In Aging's VIP testing panel. It was a truly collaborative venture. YBF was knocked out by the feedback from our community and reformulated the product.

This is not a lip plumper, but it does give lips deeper color and a fuller look while dealing with fine lines around the mouth. YBF Define is $70 in the TIA shop.

What Marta said: Personally, I thought Define 1.0 was very good and I have been using the "in beta" samples every day for going on six months. Without question, my lips are redder, fuller. Meanwhile the lines around my mouth have become fainter. My feedback to YBF was that this was a product that could potentially be every bit as powerful as the Correct eye cream (which has also been subjected to an upgrade).

What you said:

Junko: Never paid too much attention to my lips, as lipstick was never flattering. I’m a 30 year smoker, and yes 2010 is my year to quit. About a year ago I noticed black spots on my lips and started trying products to eliminate them. Nothing worked. Cancer & must see a Dermatologist in 2010 was my fear until DEFINE arrived. After 3 weeks of DEFINE, these marks are barely visible. My lips are plumper, redder and reminisent of much younger days. Thank You Marta/TIA & YBF!!!

Bev: I was one of the testers and I really liked this product. It helped soften the lines around my mouth. I don’t use a separate lip product, but will make an exception for Define. I can’t wait to purchase it!
