Microneedling radiofrequency: what it does (and what it doesn't)

In 2025, Dr. Fernando Amato was interviewed by Folha de S.Paulo (print and online) and other national portals to explain what microneedling radiofrequency really delivers — and what is being sold beyond the evidence.

How it works

Microneedles reach the deep dermis and release radiofrequency energy, generating controlled heating that stimulates neocollagenesis and remodeling. It reaches layers that creams cannot.

Real indications

• Mild to moderate skin laxity of the face and neck;
• Atrophic acne scars;
• Early striae alba (white stretch marks);
• Skin texture and enlarged pores.

What it does not replace

It does not replace plastic surgery (facelift, blepharoplasty) for moderate-severe skin laxity. It is not magic in one session — generally, 3 to 4 sessions with a monthly interval are needed.

Recovery

Redness for 24–48 h, possible mild edema. Return to activities the next day. Strict photoprotection for 30 days.
