The concept of microneedling is based on the skin’s natural ability to repair itself when it suffers physical damage such as cuts, burns, abrasions or other injuries. Immediately after an injury to the skin, our body begins the healing process, triggering new collagen synthesis. The Cosmopen is a microneedling device that intentionally creates very superficial “micro-injuries” to the outermost layer of the skin, inducing the healing process including new collagen production. Microneedling has been shown to reduce the visibility of acne scars, fine lines and wrinkles, diminish hyperpigmentation, and improve skin tone and texture, resulting in smoother, firmer, younger looking skin.


At Aria Medical Aesthetics microneedling is performed using The Cosmopen. This procedure is performed by a trained Registered Nurse, under the supervision of a healthcare provider (physician or physician assistant), who is licensed to practice medicine in the State of Connecticut. The Cosmopen microneedling procedure is performed in a safe and precise manner with a single-use sterile needle head. The treatment session usually takes about 30-60 minutes, depending on the area(s) being treated. After the procedure, the skin will be red, with mild swelling and/or bruising, and your skin might feel tight and sensitive to the touch. Although these symptoms may take 2-3 days to resolve completely, they will diminish significantly within a few hours after treatment.


Alternative treatments to microneedling may include the use of routine skin care, oral and/or topical prescription and/or non-prescription medications, microdermabrasion, dermaplaning, laser treatments, and even cosmetic/plastic surgery. However, since this treatment is elective and is done for cosmetic purpose only, no treatment at all should also be considered a viable alternative.


Although the majority of patients do not experience any complications with microneedling, it is important you understand that risks do exist. The microneedling procedure is minimally invasive, utilizing a set of microneedles to inflict multiple, tiny, puncture/lacerations to the outermost layer of the skin. Because microneedling penetrates the skin, it inherently carries health risks, including but not limited to those listed below. You should discuss any and all health concerns with your esthetician or attending healthcare provider PRIOR to signing our consent form.

INFECTION – Infection is very unusual. However, viral, bacterial, and fungal infections can occur anytime the integrity of the skin is compromised. Should infection occur, you must contact or return to our office immediately, as additional treatment will likely be necessary.

PIGMENT/COLOR CHANGE – Because dermal penetration is so superficial it doesn’t extend into the layer of the skin containing melanocytes. Hyperpigmentation is very rare with microneedling, however, failure to follow post treatment instructions can put you at risk for hyperpigmentation. You MUST avoid sun exposure for 1 to 2 weeks after a microneedling treatment. You should also wear a daily SPF facial moisturizer, which your esthetician can recommend. Lastly, avoid picking and/or peeling the skin during healing period.

SCARRING – Although normal healing after the procedure is expected, abnormal scars may occur in both the skin and deeper tissues. In rare cases, thickened or keloid scars may result, especially if you are prone to keloid scarring anyway. Scars may be unattractive and of different color than surrounding skin. Additional treatments may be needed to treat scarring.

PAIN – There may be a very slight burning, scratchy, and irritated sensation to the skin. This is usually temporary and is gone within a few hours after treatment. A sudden reappearance of redness or pain is a sign of infection and you should notify our office immediately.

PERSISTENT REDNESS, ITCHING, AND/OR SWELLING – Itching, redness, and swelling are normal parts of the healing process. These symptoms rarely persist longer than 24 hours with microneedling. However, treatments received less than 4 weeks apart may induce prolonged symptoms.

ALLERGIC REACTION – Microneedling is performed with a head containing 12 sterile hypodermic needles, making an allergic reaction nearly impossible. However, a variety of products may be used on the face in conjunction with the microneedling procedure, to which an allergy can occur. Additionally, since microneedling increases the penetration of topical substances, it can cause you to be hypersensitive to products used on the face. If an allergic reaction were to occur, you must contact our office immediately, as it may require further treatment.

LACK OF PERMANENT RESULT – Microneedling will not completely or permanently improve skin texture, tone, elasticity, hyperpigmentation, scars, or minimize fine lines and wrinkles. It is important that your expectations be realistic and understand the procedure has its limitations. Additional procedures may be necessary to achieve desired effect.

UNSATISFACTORY RESULT– Although rare from microneedling, there is a possibility of a poor result from any cosmetic procedure. Microneedling may induce undesirable results, including but not limited to skin sloughing, scarring, permanent pigment, and/or other undesirable skin changes. You may be disappointed with the final results of microneedling.

CONTRAINDICATIONS TO MICRONEEDLING – Although it is impossible to list every potential risk and complication, the following are recognized as known contraindications to microneedling. Furthermore, it is your responsibility to fully and accurately disclose all medical history prior to initial treatment, as well as provide any necessary updates at all future treatment sessions. If you have any of the conditions listed below, you should bring it to the attention of your esthetician PRIOR to signing this consent form.
