Is it just aging? Too much sun? Too much stress? In general, how skin ages and wrinkles is a complex process. It isn’t just about cellular changes, collagen depletion, hormone loss, damage caused by free radicals, and so on; it’s a combination of many factors.

The lines that appear between your brows (glabellar lines) actually result from muscle movement and the passage of time. You may have heard the expression “wearing your emotions on your sleeve,” but in reality you wear them on your face. If you’re angry or annoyed, for example, you knit your brows together. Underneath your skin, your facial muscles contract, cause a pleating of the overlying skin, and then, as anyone can see, you’re frowning.

After years of crinkling and wrinkling, those glabellar lines start to linger longer and can become more pronounced. For women, whose faces tend to be more animated than men’s, and whose skin is typically more delicate, these lines may appear exaggerated and more permanent.

Fortunately, there is a way to temporarily reduce moderate to severe lines between your brows (glabellar), in your forehead (frontallis), and around your eyes (“crows feet”).

Treatment with BOTOX¬ Cosmetic can visibly smooth and soften moderate to severe frown lines between your brows. An improvement can be seen within days and may last up to 4 months, although results may vary. In clinical trials, nearly 90% of men and women surveyed rated the improvement in the appearance of frown lines between their brows as moderate to better 1 month after treatment
