Does microneedling enhance lips?

Thank you for your question about microneedling.  Microneedling with PRP (platelet rich plasma) will make an impact on your skin texture and pore size.   Everyone is different in how soon they will see results from their treatment. You will often begin to see smoother brighter skin within 1-2 days. Your skin actually continues to improve over time (weeks to months) with collagen remodeling underneath the skin's surface. Within the first 2-3 weeks, most patients will see their pigmentation improve, followed by deeper skin regeneration that keeps improving over the ensuing months.  Collagen production will have longer lasting results, but does take several months to see benefits.  
However, our office does not microneedling on the lips specifically, but we do microneedling in the perioral area.  Hyaluronic acid based fillers are a wonderful option for specifically in the lips.  Hyaluronic acid is hydrophilic by nature, so that is why you have an improvement in lines and wrinkles (or areas of volume loss) immediately following treatment.
To be sure you receive appropriate treatment, see two or more experienced, licensed and board-certified providers in your area for a complete evaluation to make sure you are a good candidate and that it is safe for you to have treatment. I hope this helps.

Microneedling is a good option for stimulating collagen. The combination with topicals ie hylaronic acid, vitamin C, retinoids, peptides... gives the best results. Microneedling is excellent on the rhytids (wrinkles) above the lips but should not be used on the lips themselves. Remember to take an antiviral prior to the procedure if you are prone to cold sores.
