How deep does HIFU penetrate?

HIFU (High-Intensity Focused Ultrasound) is a non-invasive procedure that targets different layers of the skin and underlying tissues to promote collagen production and skin tightening.

Depth of Penetration:

• 1.5 mm – Targets the epidermis and superficial dermis, improving skin texture and fine lines.
• 3.0 mm – Reaches the deep dermis, stimulating collagen production for skin tightening.
• 4.5 mm – Penetrates the Superficial Musculoaponeurotic System (SMAS), the same layer tightened during surgical facelifts.
• 6.0 mm to 13.0 mm – Used for body contouring, targeting deeper fat layers and connective tissues.

Factors Affecting Penetration Depth:

• The area being treated (face, neck, or body).
• The specific HIFU device and its settings.
• The patient’s skin thickness and condition.

Effects Based on Depth:

• 1.5 mm & 3.0 mm: Improves skin elasticity, reduces fine lines, and enhances overall skin texture.
• 4.5 mm: Provides deep tissue tightening, often compared to a non-surgical facelift.
• 6.0 mm to 13.0 mm: Used for fat reduction and skin firming in body contouring treatments.

Final Verdict:

HIFU penetrates at varying depths depending on the treatment goals, ranging from 1.5 mm for skin rejuvenation to 13.0 mm for fat reduction and body contouring. This targeted approach makes it an effective non-surgical alternative for lifting and tightening the skin.
