Filler across the cheeks, folds, and jawline swells for two to three days and bruises where vessels are crossed, particularly near the marionette lines. Along the jaw the product feels firm to the touch for some weeks, which is expected. It can migrate slightly, form nodules, or look uneven, and adjustment is sometimes needed. Infection is uncommon. Vascular occlusion causing damage to the skin is rare and is treated urgently. Volume declines over six to eighteen months.
Beneath the eye, bruising is likely and swelling can obscure the outcome for one to two weeks. Because that skin is thin, material sitting too high may show as a bump or a Tyndall type bluish shadow, and it takes time to soften. The two sides rarely settle identically. Infection is rare. Absorption occurs over months, so the area gradually returns toward its previous appearance without further sessions.
