Are There Bad Side Effects to Microneedling?

Wonderful question.  Microneedling can stimulate collagen regeneration and when combined with PRP it can improve scars in a variety of skin types.  The expectations of treatment are pinpoint bleeding and localized irritation.  Side effects are rare when the correct technique is used.  I have never seen this but possible rare side effects include infection, hyperpigmentation or worse scarring.  It is also possible that there may be no improvement in your scars if the correct depth is not used.

HiWe use Micro-needling frequently for treatment of acne scarring and its very effective and safe. We use the traditional roller method combined with Environ and our newest version called SkinPen which has less downtime.If performed correctly there is little risk involved. At consultation you will be made aware of all details regarding aftercare, contra-actions and contraindications.I would recommend finding a local clinic and going for a consultation.Hop this helps

Microneedling is a great treatment for textural acne scars as it helps produce collagen and elastin and can be used safely on all skin-types. There can be some redness, swelling and pinpoint bleeding after treatment, but these are all normal reactions. We also offer microneedling with PRP (platelet rich plasma) which can help shorten recovery time and deliver growth factors to your skin for added skin rejuvenation. Typically we recommend 4-6 treatments depending on the severity of the scarring. 

 Microneedling  has become the most popular procedure for many skin conditions, such as enlarged pores, fine lines, perioral rhytides, wrinkles, minor sagging, pigmentation, many types of scars including acne scars, striae and stretch marks on any part of the body. There are many different types of microneedling devices such as Intensif RF microneedling, and microneedling without heat such as skinpen, dermapen, cosmopen and collagen PIN. 
Microneedling procedures in certain states like MA are regulated and have to performed by qualified individuals ( is outside the scope of practice of Estheticians and Registered Nurses in MA). 
The Microneedling procedure can be combined with other procedures such as Micro-dermabrasion, Peels, Lasers, Subcision, Platelet rich plasma, Botox, Sculptra and Hyaluronic acid. It is also used to enhance the delivery of drugs for many other pathological skin conditions.
The most common side effects are pain, erythema, bleeding and swelling. Some rare complications such as infection, herpes simplex, scarring, hyperpigmentation and granulomas are also reported. 
The keys to minimizing side effects would be - detailed medical evaluation with your physician prior to the procedure, preparing the skin for better results, using strict aseptic techniques while performing Microneedling and following post procedure guidelines devised by your physician.
  

Microneedling is a great treatment option used to treat a variety of skin conditions such as acne scars, fine lines and wrinkles and photo damage by stimulating collagen production. During the procedure, the Cosmopen, a state-of-the-art microneedling device is used to create microscopic channels. While the microscopic channels heal, collagen and elastin are naturally produced by your body, encouraging your skin to shrink, tighten and diminish the appearance of acne scars. When choosing a provider, it is essential to do your research. Make sure the provider is an elite and certified provider at a dermatologist, facial plastic surgeon or medical aesthetic practice. 
Although there is no downtime related to microneedling treatments, some patients may see up to 24 hours of redness. Patients are able to resume normal, daily activities the following day.
