Ulthera is a procedure that utilizes High-Intensity Focused Ultrasound (HIFU) like a magnifying glass to induce thermal damage at specific depths within the skin, thereby promoting collagen regeneration. This regenerative process gradually unfolds over approximately six months, leading to progressive skin improvement and sustained elasticity.
While the generally recommended interval for Ulthera treatment is one year, its effects continue to improve for six months. For individuals experiencing rapid aging or those with significant signs of aging, an additional treatment can be considered after six months. Just as with regular health check-ups, receiving appropriate skin treatments periodically can significantly help in slowing down the aging process and maintaining a youthful appearance.
