Overview
Fractional radiofrequency microneedling is used as a nonsurgical facelift. Redness, pain, swelling and bruising after it typically last up to 7 days. The authors state no published studies have tested topical agents to speed recovery. This case report describes two patients who had recombinant human collagen applied to the treated skin immediately after the procedure.
Findings
- 2 women, both 40 years old, Fitzpatrick skin type IV.
- Microneedling done with standard energy settings.
- Topical recombinant collagen applied immediately after the procedure.
- Changes in redness and swelling were recorded with clinical photography or cross-polarized imaging.
- Both showed a marked reduction of redness and inflammation within 1 to 2 hours.
- This was earlier than the typical 1 to 3 days.
- No adverse events.
- Known risks of the procedure listed in the background: prolonged swelling, infection, persistent grid marks, burns, and darkening or lightening of the skin.
What it means for a patient
- After radiofrequency microneedling, expect redness and swelling for up to about a week.
- In these two patients, a collagen product applied right away was followed by faster calming of the skin.
- Limits: two patients, no comparison group, and very short follow-up. The result cannot show that the collagen caused the change.
Why this paper matters
It is an early report of a topical agent used to shorten recovery after radiofrequency microneedling. It suggests a question for controlled studies rather than an answer.
Terms
- Fractional radiofrequency microneedling: fine needles that deliver radiofrequency heat into the skin in a grid pattern.
- Recombinant human collagen: collagen made in the lab from human genetic code.
- Erythema: redness of the skin.
- Fitzpatrick skin type IV: a skin type that tans easily and rarely burns, often olive or light brown.
- Cross-polarized imaging: photography that filters surface glare to show redness and pigment.
- Hyperpigmentation and hypopigmentation: darker or lighter patches of skin.
- Nonsurgical facelift: a treatment that aims to tighten or lift the face without surgery.
