What is Microneedling
Microneedling is a dermaroller procedure that uses small needles to prick the skin. The purpose of treatment is to generate new collagen and skin tissue for smoother, firmer, more toned skin. Microneedling is mostly used on the face and may treat various scars, wrinkles, and large pores.
 
Procedure for microneedling
During the procedure, the therapist makes small pricks under the skin with a pen-like tool. The pinpricks are so small that you likely won’t notice them after the procedure. Your therapist will move the tool evenly across your skin so that the new skin that rejuvenates will be even, too. Before getting started, a topical anesthetic is used to reduce the chances of pain. This is done about an hour before your treatment. 
 
How does it work
Microneedling works by encouraging your skin to make more collagen. The idea is that pinpricks from the procedure cause slight injury to the skin and that the skin responds by making new collagen-rich tissue. This new skin tissue is, in turn, more even in tone and texture. It’s normal for the skin to lose collagen via age or injury. By encouraging the skin to make new tissue, there may be more collagen to help make the skin firmer, too.
 
Preparing for microneedling
Before the procedure, talk to your therapist about ways you can prepare so you have the best possible outcome. You may need to stop taking certain medications, such as ibuprofen and those for acne treatment, well in advance of the procedure. Your therapist may also recommend that you stop using topical retinoids beforehand too. Doing so may reduce the risk of certain side effects.
 
Safety:
Microneedling is minimally invasive, requiring no downtime. It’s considered safe for most people who are in overall good health. The procedure isn’t safe for people who use certain acne medications or for women who are pregnant. You’ll experience minor redness and irritation for a few days after the procedure.
 
Targeted areas for microneedling and benefits
Microneedling is most often used on your face to target:
acne scars
age spots (also called “sunspots”)
fine lines and wrinkles
large pores
other types of scars
reduced skin elasticity
uneven skin tone
In addition to facial concerns, microneedling is sometimes used to treat stretch marks in other areas of the body. 
 Microneedling is considered effective in treating minor scarring related to acne, wounds, and aging. You’ll likely notice brighter, firmer skin, too. Ideal results are achieved after multiple sessions.
 
Are there any risks or side effects
Like all cosmetic procedures, microneedling isn’t without risk. The most common side effect is minor skin irritation immediately following the procedure. You may also see redness for a few days. Call your doctor if you notice more severe side effects, such as: Bleeding, bruising, infection, peeling

You may not be an ideal candidate for microneedling if you:
are pregnant
have certain skin diseases, such as psoriasis or eczema
have open wounds
have had radiation therapy recently
have a history of skin scars
 
What to expect after microneedling
Microneedling isn’t invasive like plastic surgery, so the recovery time is minimal. most people require very little downtime, if any at all. You may notice skin irritation and redness within the first few days following the procedure. This is a natural response to the small “injuries” made by the needles in your skin. You can go back to work after the procedure if you’re comfortable. Some people apply camouflaging makeup during the first few days as the redness dissipates. Your skin will also be more sensitive to the sun, so sunscreen is a must. After microneedling, your skin works fairly quickly to rejuvenate new tissue. In theory, you should see results within a couple of weeks. To maintain the results of your treatment, you’ll need multiple sessions and perhaps other complementing treatments. Your therapist will advise you on the best plan of action based on your individual goals.
