Micro needling, also known as collagen induction therapy or dermarolling, is a skin care treatment that involves using a device covered in tiny needles to create microscopic punctures in the top layer of the skin. The goal is to stimulate collagen and elastin production, as well as improve product absorption. Micro needling can be performed at home with handheld devices called micro needle rollers or dermarollers.
Micro needle rollers are small cylindrical devices covered in hundreds of tiny needles. When rolled across the skin, the needles create tiny "injuries" that signal the body to produce new collagen and elastin. This increases skin thickness and elasticity over time. Micro needle rollers are primarily used on the face and scalp to treat wrinkles, acne scars, and hair loss. However, they can be used on other areas of the body as well.
In this comprehensive guide, we will cover everything you need to know about how to properly use a micro needle roller at home, including:
· Benefits of micro needling
· Types of micro needle rollers
· Needle length and size
· How to prepare your skin
· Proper rolling techniques
· Aftercare
· Treatment schedule
· Safety precautions
Understanding the ins and outs of at-home micro needling will help you achieve optimal results safely and effectively.
Used correctly, micro needling offers several benefits:
· Collagen induction - The micro injuries created by the needles stimulate your body's natural wound healing process, increasing collagen and elastin production. This gives skin a thicker, more youthful appearance over time.
· Reduces wrinkles and fine lines - By boosting collagen, micro needling can reduce the appearance of fine lines, wrinkles, and other signs of aging. Results are especially noticeable on the forehead and around the eyes, mouth, and décolletage.
· Evens out skin texture - The collagen stimulation helps even out indentations and scars from acne, chickenpox, and other skin conditions. It is an effective treatment for enlarged pores as well.
· Fades acne scars - Along with boosting collagen, micro needling breaks up scar tissue and allows skincare products to better penetrate the skin. This reduces the appearance of atrophic acne scars.
· Minimizes stretch marks - When used in early stages, micro needling may help decrease the appearance of stretch marks by increasing elastin production. Results are best on breast and belly stretch marks.
· Promotes hair growth - Needling stimulates blood circulation and follicle stem cell activity in the scalp. When combined with treatments like minoxidil, it can help with male and female pattern baldness.
· Enhances product absorption - The microscopic punctures allow skincare ingredients to penetrate deeper into the skin. Serums and creams become more effective when used after micro needling.
Overall, micro needling improves the tone, texture, firmness and glow of the skin for a more youthful appearance. When performed correctly, it is safe for all skin types and tones.
There are three main types of at-home micro needle rollers:
These are the most affordable option but still provide results. The needles are arranged on a plastic roller that is manually rolled over the skin. Plastic rollers come in needle lengths ranging from 0.25mm to 1.5mm. They are the best choice for beginners.
Titanium rollers offer increased durability and penetration compared to plastic. The titanium material allows the needles to be packed more densely. Titanium rollers have needle lengths between 0.25mm and 1mm. The lightweight metal is ideal for rolling over curved areas like the face.
These automated devices use microneedle tips that oscillate rapidly to penetrate the skin. Electronic rollers offer adjustable needle depth and speed settings. The motorization provides increased precision and reduces hand strains. However, they are the most expensive option.
When choosing a device, keep your skin goals and pain tolerance in mind. Shorter needle lengths like 0.25-0.5mm are best for beginners or sensitive areas. Longer 1-1.5mm needles provide deeper penetration but require a higher pain threshold. Always start slowly and adjust as needed.
Micro needle rollers contain hundreds of microneedles on a cylindrical surface. Needle length typically ranges from 0.25mm to 1.5mm. The length you choose impacts the depth of penetration:
· 0.25-0.3mm - Shallow penetration into the epidermis. Best for product absorption and very sensitive skin.
· 0.5mm - Penetrates into the epidermis. Effective for general collagen induction and skincare enhancement. The most popular all-purpose length.
· 0.75-1.0mm - Reaches the dermis for increased collagen stimulation. Requires some pain tolerance. Provides deeper treatment of scars and wrinkles.
· 1.25-1.5mm - Penetrates deep into the dermis. Longer needles have the most impact on collagen but require the highest pain tolerance. Best for skin with severe scarring or stretch marks.
Keep in mind that longer needles increase the risk of damage if used incorrectly. Start with a 0.5mm roller and only increase needle length gradually as your skin adjusts. Never use longer than a 1.5mm roller at home.
The diameter or width of the roller also varies, typically between 10mm to 30mm. Wider rollers allow you to cover more surface area, making treatment faster. However, small rollers like 15mm are preferable for rolling over curved areas like the nose and eyes.
Properly preparing your skin before micro needling is crucial for safety and results:
· Cleanse and dry the skin - Remove dirt, oil and makeup so needles can penetrate efficiently. Gently pat dry after cleansing.
· Skip actives - Avoid using exfoliants, retinoids and acidic products 1-2 days before needling. This prevents irritation.
· No sun exposure - Protect skin from the sun 1 week before and after. Tanned skin is more prone to damage.
· Trim facial hair - Shave or trim any hair in the treatment area to allow proper needle penetration. Avoid waxing for a few days prior.
· Numbing cream - Apply a topical anesthetic like lidocaine cream 30-60 minutes before longer needling sessions to minimize discomfort.
· Sterilize device - Disinfect your micro needle roller before and after each use to prevent infection.
Follow all preparation steps even if doing a quick 5-minute session. A clean face and sterilized device reduces the risk of complications.
Once your face is prepped, follow these steps for safe and effective facial micro needling:
1. Start with a clean micro needle roller. Sterilize according to manufacturer instructions, usually by wiping with rubbing alcohol.
2. Wash hands thoroughly and ensure fingernails are trimmed to avoid damaging the needles.
3. Cleanse face and pat completely dry. Apply a numbing cream if desired and wait 30-60 minutes.
4. Start at one corner of the face near the jawline. Stretch skin taut between fingers.
5. In vertical motions, firmly roll the device upwards and outwards across the cheek. Apply moderate pressure so the needles penetrate skin, but not enough to cause pain or damage.
6. Work upwards towards the eye and temple, rolling in parallel columns to cover the entire cheek area.
7. Use the opposite hand to stabilize the skin for controlled, even needling. Apply more pressure over scarred areas.
8. Continue into the forehead and temple using the same rolling technique. Use small circular motions around the contours of the eye and nose.
9. Roll down the other side of the face from jawline to temple. Finish by gently rolling any sensitive areas like around the lips.
10. Apply a hyaluronic serum, moisturizer, or other skincare product to help retain moisture after needling. Avoid harsh active ingredients.
11. Thoroughly clean the roller with alcohol to disinfect after each facial treatment.
Aim for 8-10 passes over each section of skin. Be very gentle when needling bony areas like around the eyes. Never roll over open wounds, moles, or raised skin tags.
Using a micro needle roller on the scalp claims to promote healthier, thicker hair growth. Here are some tips for needling your scalp at home:
1. Sterilize a new roller before use. Titanium rollers 0.5mm-1mm are recommended for scalp needling.
2. Part clean, dry hair into sections. Use clips to expose the scalp skin.
3. Holding the roller perpendicular to the scalp, gently roll upwards and outwards across each section. Apply moderate pressure.
4. Focus needling in areas of hair thinning or loss. Use circular motions along the hairline and temples.
5. After needling, apply a hair growth serum containing nutrients like biotin, vitamin E, or rosemary oil.
6. Repeat 1-2 times per week for a minimum of 6 weeks. Combine with minoxidil for enhanced results.
7. Cleanse roller thoroughly before and after each use. Replace every 4-6 months to reduce infection risks.
Avoid pressing too hard or causing bleeding/abrasions on the scalp. Only roll once the area is healed between sessions. Monitor for skin irritation and discomfort. Done properly, consistent scalp needling and treatments can lead to thicker, fuller hair over time.
Micro needling can reduce the indented appearance of stretch marks, especially when started early. Follow these tips for stretching needling:
1. Cleanse skin and apply numbing cream to the area if desired.
2. Use a 0.5mm-1mm roller. Sterilize before use.
3. Gently pinch up the stretch marked skin and roll perpendicularly across the length of the mark.
4. Roll back and forth over each mark 8-10 times using light pressure.
5. After needling, gently massage in a collagen-boosting cream or oil like coconut or vitamin E oil.
6. Repeat every 7-14 days for 8 weeks minimum. Schedule sessions after a warm shower when skin is relaxed.
7. Avoid needling infected, irritated or freshly stretched skin. Discontinue if skin becomes overly red or inflamed.
8. Clean roller thoroughly after each session.
Consistency is key for reducing the appearance of stretch marks over time. Combine needling with collagen-boosting ingredients for enhanced results. Use sun protection between sessions.
When first starting, limit micro needling sessions to once every 2-4 weeks. This allows sufficient time for minor skin injury to completely heal between rollings. After a few months, many users find they can increase frequency to every 1-2 weeks.
However, avoid micro needling the same area of skin too often. Stick to the following schedule based on needle length:
· 0.25-0.3mm needles - 1-2 times per week
· 0.5-0.75mm needles - Once every 7-14 days
· 1-1.5mm needles - Once every 2-4 weeks (no more than monthly)
The skin on the face, neck and body will require more recovery time than hands or feet. Use shorter needling sessions if increasing frequency to once weekly. Monitor skin closely and reduce session length or frequency if irritation occurs.
Take at least one month off every 3-4 months to allow your skin to rest. The collagen boosting effects of micro needling accumulate over time. There is no added benefit to overdoing sessions.
Proper cleaning and storage extends the longevity of your device:
· Sterilize before and after use - Soak in isopropyl alcohol for 15-20 minutes to fully disinfect. Rinse and allow to air dry.
· Replace roller caps - Place protective cover back on roller after cleaning or needles may dull.
· Avoid touching needles - Hands transfer dirt and oils onto needles, increasing infection risks.
· Store in sealed case - Keep in an airtight container to prevent dust buildup between uses.
· Avoid direct sunlight - Light exposure weakens needles, making them prone to bending and dulling.
· Replace every 4-6 months - Old or damaged rollers increase risks of skin trauma. Replace sooner if needles are blunt or bent.
Proper sterilization before each and every use is vital. Skipping this step can lead to pimples, infection and skin irritation. Invest in a quality roller and follow care instructions to maximize longevity.
Yes, as long as you choose the right device and use proper technique, micro needle rollers can be an effective way to boost collagen, reduce scars, wrinkles, and enhance absorption of skincare products. However, results take time and consistency.
Clinical studies support the benefits of at-home microneedling:
· A 2009 study found that using a 1.5mm roller twice weekly significantly improved acne scarring after three months compared to no treatment.
· In a 2014 study, participants needled with a 0.5mm roller saw increased collagen production and skin thickness after just one week. Effects continued increasing over 12 weeks.
· Research in the Journal of Investigative Dermatology found that needling once weekly effectively reduced fine lines and wrinkles around the eyes after 6 weeks.
While individual results vary, the evidence shows micro needling improves various skin concerns when performed properly over time. Have realistic expectations and stick to a regular schedule for optimal results. And remember to always take necessary safety precautions.
While generally safe when protocols are followed, some risks of micro needling include:
· Infection - If the roller is not properly sterilized between uses, bacteria can colonize on the device and cause pimples or other infections.
· Bruising/bleeding - Excessive pressure can rupture capillaries and cause pinpoint bleeding and skin discoloration that takes days to fade.
· Scarring - Using needles that are too long or rolling too forcefully can potentially cause scar formation. This is rare with proper technique.
· Hyperpigmentation - Darker skin is more susceptible to post-inflammatory hyperpigmentation and other discoloration issues. Stay out of the sun and avoid rolling irritated skin.
· Herpes outbreak - Needling around active cold sores can push the virus deeper. This may lead to widespread facial outbreaks. Wait until healed.
Carefully following protocols and aftercare reduces risks of complications. Consult a dermatologist before trying micro needling if you have very sensitive skin, take blood thinners or have a history of cold sores/HPV. Consistency and patience lead to the best long-term results.
When done correctly, micro needling can be a safe, effective way to address various skin concerns from the comfort of home. Consider your personal skin goals and pain tolerance when selecting a needle length. Start slowly, properly sterilize the device before each use, and be diligent with aftercare.
While results require consistency and patience, the collagen and elastin boosting effects make micro needling worthwhile for improving texture, elasticity, firmness and glow. With the proper precautions, micro needle rollers can be a lasting addition to your skincare routine. Just be sure to do your research and consult a dermatologist if you have any concerns before getting started.
