4 microneedling treatments of facial skin, spaced 4 weeks apart, significantly improved lines, wrinkles, skin laxity, and skin texture, 90 and 150 days after the first treatment, according to a recent study. Furthermore, side effects were minor and easily managed compared to other invasive technologies, such as laser ablation and radiofrequency. 48 subjects aged 35 to 75 years with signs of facial skin aging were recruited. After consenting and satisfying inclusion criteria, each subject underwent 4 microneedling sessions 30 days apart. Subjects were assessed at baseline and at 30, 60, 90, and 150 days after the first treatment. Researchers found:
- Mean improvements in global wrinkle score (mean of 9 facial area grades), skin laxity, and skin texture at day 150, compared to baseline were 1.23, 1.09, and 1.54, respectively.
- Statistically significant mean improvements in these 3 measures were also observed at day 90.
- The treatment was well tolerated with minimal pain, discomfort, and downtime.
