HIFU Skin Tightening
Focused ultrasound lifts and firms the brow, jawline and neck by rebuilding collagen in the deep layers — no cuts, no needles, minimal downtime.
HIFU — high-intensity focused ultrasound — is a non-invasive skin-tightening treatment. It focuses ultrasound energy at precise depths under the skin, reaching the same deep support layer a surgical facelift works on, without cutting the surface at all.
How HIFU works
The device places tiny points of heat at set depths — the deep foundation layer and the deeper dermis. Each heated point contracts tissue slightly and triggers the body to build fresh collagen around it over the following weeks. The surface skin is untouched, which is why there is no wound and essentially no downtime.
What it treats
HIFU suits mild-to-moderate skin laxity: a softening jawline, early jowls, a heavy brow, loose skin under the chin and on the neck, and general firmness of the lower face. It maintains and lifts — it is not a replacement for surgery in advanced laxity, and an honest consultation will say so when that is the case.
What to expect
A session takes roughly thirty to ninety minutes depending on the area. You feel a deep, prickling heat as each line of energy is placed; most people tolerate it well. A faint lift can show early, but the real change builds over two to three months as new collagen forms, and typically lasts from six months to about a year and a half.
Safety and side effects
Common effects are temporary: redness, mild swelling and tenderness for a few days. Occasionally an area feels briefly numb or tingly as small nerves settle — this passes. Correct depth selection and energy settings for your anatomy are what keep HIFU safe and effective, which is why it should be done by a trained physician after an assessment.
Dr. Mostafa Havasi performs HIFU in Karaj (Azimieh) and Tehran (Chitgar). A private consultation confirms whether your degree of laxity will actually respond — and says honestly when it won’t.

Frequently asked questions
Is HIFU painful?
You feel a deep prickling heat as each line of energy is placed; most people tolerate it well, and any tenderness settles within a day or two.
Is there any downtime?
Very little — there are no needles or cuts, so most people return to their day at once, sometimes with mild swelling for a day or two.
When will I see results, and how long do they last?
A faint lift shows early, but the real change builds over two to three months as new collagen forms, and typically lasts six months to about a year and a half.
Where can I have HIFU in Karaj?
HIFU is performed by Dr. Mostafa Havasi at the Azimieh clinic in Karaj (with a second clinic in Tehran, Chitgar); a private consultation confirms whether it’s the right lift for you.
