Will spacing microneedling treatments 8 weeks apart achieve the same results as 4-6 weeks apart?

The timetable for upregulation of fibroblasts (which are the cells that need to be turned on to produce collagen) is variable in location and between people but in general a more frequent trauma is more likely to augment the machinery of collagen synthesis.

Initially it is recommend to do a series of 3-6  treatments at 4-6 weeks apart, then you can space them out to 8-12 weeks to maintain and keep the skin rejuvenated. By following this regimin you will not cause damage to the skin, you will improve overall appearance, elasticity, keeping the skin smooth and inducing collagen production. I do recommend using PRP with your microneedling treatments. Best to you!

It depends on what your goals and concerns are and whether it is for acne scars or reducing fine lines and wrinkles. Usually for patients trying to reduce those areas of concerns, treatments 4 to 6 weeks closer together is recommended.  After that, spacing it out 8 to 12 weeks is fine and will still yield good results. It's like going to the gym regularly and as long as you maintain a consistent schedule there should be good results.Chase Lay, MD
