Jawline slimming creates a slimmer lower face, often with masseter botulinum toxin to relax enlarged jaw muscles, sometimes combined with fat-dissolving injections or lifting devices. It is a popular V-line treatment in Korea. At Louave in Cheongdam, Gangnam, Seoul, a dermatologist assesses whether muscle, fat or laxity is the cause.
