Wrinkle Relaxant Cosmetic injections are a very popular cosmetic treatment performed at our practice. This procedure can temporarily erase fine lines and wrinkles on the face, particularly furrows between the brows and crow's feet wrinkles. Wrinkle Relaxant Cosmetic consists a low concentration of muscle relaxant that works to prevent facial muscles from contracting. Since muscle contracture causes wrinkling, the treatment is highly effective in temporarily paralysing the muscles, smoothing out wrinkles and fine lines. The treatment can also decrease the presence of troublesome muscle bands that form on the neck during aging. Results appear in about one week, and patients can come in for repeat injections once the effects have worn off.
