Microneedling therapy has become a popular method for many beauty lovers who pursue skin rejuvenation, because microneedling can not only be done in beauty clinics, but also can be done at home by yourself, after purchasing a skin booster suitable for yourself.
As one of the core tools of microneedling therapy, derma rollers have gradually entered the home for daily skin care routine from professional medical beauty institutions. The characteristics of derma rollers are easy to operate, novices can also quickly get started, and they can be used multiple times after cleaning.
Through the rolling stimulation of hundreds of tiny needles, it can create tiny channels on the surface of the skin. These tiny channels allow skin boosters to smoothly enter the dermis of the skin and maximize the role of skin boosters. In addition, these tiny wounds can activate the self-repair mechanism of the skin, thereby achieving the effect of improving skin quality.
However, many people have a question when they first come into contact with Derma Roller: Which derma roller size is the best?
In fact, different needle lengths have different purposes and suitable people. Choosing the wrong size will not only have poor results, but may even damage the skin.
Therefore, you need to understand what size roller needle is suitable for you.
What is Derma Roller?
Derma roller is a portable instrument for microneedling treatment. It is roughly composed of two parts: a handle and a roller. The roller is inlaid with hundreds of tiny metal needles. Common materials include stainless steel and titanium alloy. During use, hundreds of tiny puncture holes are made on the skin surface by rolling.
These micropores that are difficult to detect with the naked eye will not leave trauma and scars after healing, but can effectively activate the skin's self-repair mechanism. After 3-5 days of repair after procedure, the skin can promote the production of collagen and make the skin smoother and more delicate.
At the same time, these micropores can also greatly improve the penetration efficiency of skin care products, help the penetration of hyaluronic acid stock solution, collagen and other solutions, and exert their maximum efficacy, which is very helpful to the skin.
According to the different needle lengths, Derma roller can be divided into two categories: beauty grade and medical grade. Different lengths correspond to different effects and applicable areas. Next, we will explain in detail the functions of each length of needle from the shortest 0.2mm to the longest 3.0mm.
Detailed explanation of common derma roller needle sizes - Which derma roller size is best？
1. 0.2mm-0.3mm: Daily maintenance microneedling
This is the most suitable needle length for beginners and daily use. The penetration depth is shallow and almost does not involve the dermis. The main function is to stimulate the skin stratum corneum and temporarily open the skin microchannels, thereby enhancing the absorption of skin care products.
It is helpful to improve dull skin tone and dry skin. It can correct the red blood on the face and the dark circles under the eyes, and can fully hydrate the skin.
This type of microneedling is almost painless and does not require a recovery period after use. It is very suitable for people with sensitive skin and skin care beginners.
It is recommended to use it 2-3 times a week, and it can be used with hyaluronic acid or mild essence for better results.
It is worth noting that this type of derma roller mainly promotes the absorption of essence and does not have deep repair or anti-aging effects.
2. 0.5mm: Mild therapeutic microneedling
When you want to improve problems such as large pores, uneven skin tone, and dark spots, a 0.5mm derma roller will be a good choice. This length of needle can penetrate the stratum corneum and the superficial dermis, effectively stimulate the production of collagen, and improve the firmness and glossiness of the skin.
There will be a slight tingling sensation when using a 0.5mm needle. You can use an anesthetic cream to anesthetize the facial epidermis before the operation. There may be a temporary redness and slight swelling after the operation, which usually recovers within 24 hours.
As the 0.5mm needle length will cause certain damage to the skin, it is advisable to use it once every 2 weeks. When using this length for the first time, pay special attention to the number of times the roller is rolled to make the small injuries on the face more even.
3. 0.75-1.0mm: Moderate therapeutic microneedling
The 0.75mm-1.0mm roller can pierce the skin deeper and is suitable for acne scars, spots, early wrinkles and other problems. The needle of this length can penetrate into the dermis, strongly stimulate the regeneration of skin tissue, stimulate the production of collagen, and have a more obvious effect on improving skin quality.
This type of derma roller is suitable for the face, neck and other parts to correct fine lines on the neck. The frequency of use should be controlled to once every 3-4 weeks to avoid excessive stimulation of the skin.
The roller and facial skin must be thoroughly disinfected before operation. After operation, it is recommended to apply a calming and repairing mask, such as the Diaminy repair mask after microneedling, which helps to relieve redness and promote repair.
4. 1.5mm: Deep repair microneedling
When skin problems are more serious, such as deep acne scars, stretch marks, deeper nasolabial folds or obvious relaxation, you can consider using a 1.5mm derma roller. It can also be used for scalp treatment and hair loss treatment. This length can penetrate into the middle dermis and is suitable for local areas of the face or body parts such as thighs, abdomen, buttocks, etc.
The operation of 1.5mm microneedlings is relatively irritating, and usually requires a 3-5 day recovery period after surgery. It is recommended to use it once every 6-8 weeks, and it is not suitable for large-scale operations. It is best to be operated by experienced users or professionals.
5. 2.0mm-3.0mm: Medical-grade deep microneedlings
This type of needle is extremely deep and is only suitable for professional medical beauty institutions. It is mainly used to treat severe scars, stretch marks, scars after burns, severe muscle relaxation and other problems. Needles of this length will cause obvious bleeding and pain. The operation process requires anesthesia, and the recovery period after surgery is long.
This needle length is not recommended for personal home use. If such deep repair is really necessary, you must go to a professional beauty clinic for treatment and choose a qualified and experienced doctor.
How to Scientifically Choose the Size of the Derma Roller?
For the question, Which derma roller size is best? It is based on the following aspects.
Clear skin goals: If you just want to improve the absorption efficiency of skin care products, 0.2mm-0.3mm is enough; if you need to lighten spots and anti-aging, you can choose 0.5mm-1.0mm; if you need to deeply repair acne scars or stretch marks, 1.5mm or more can achieve the maximum effect.
Consider skin tolerance: First, you need to evaluate your skin condition and consider whether your skin is sensitive. Sensitive skin is recommended to start with a short needle length and try gradually; while those with strong tolerance can choose a longer needle according to actual needs.
Select size by zone: Choose derma rollers with different needle lengths for different parts of the face. For example, short needles are suitable for weak skin areas such as around the eyes and lips, while long needles can be used for cheeks, jawline, and body parts, so as to achieve "size by part".
Experience and technical mastery: Beginners are recommended to use products of 0.5mm or less to avoid allergies or skin breakage caused by improper operation. After proficiency in operation, use 0.75 or 1mm rollers for operation.
Types of Derma Roller
Before choosing the appropriate needle length, need to understand the types of microneedling products in order to choose the style that suits us. Currently, Diaminy store provides three derma rollers: Derma Roller 540, Derma Roller 192 and Derma Stamp 140.
Although they are all tools for microneedle treatment, they also have their own advantages in actual efficacy.
1. Derma Roller 540
Derma Roller 540 is the most common rolling needle device. Its characteristics are that the needles are densely distributed, which can improve the coverage efficiency during treatment. It can be used on a large area of the face and body. It is suitable for evenly introducing skin care products, improving dull skin, mild fine lines, dryness and peeling.
2. Derma Roller 192
Compared with the 540 needle style, Derma Roller 192 uses fewer needles and is relatively sparsely arranged. The stimulation is more concentrated and more suitable for deep repair, such as acne marks, scars and other treatments.
3. Derma Stamp 140
Derma Stamp 140 is not a traditional roller structure, but a stamp-like device with 140 needles. Its operation method is to press the needles vertically into the skin, which is obviously different from the above two devices.
It is more suitable for treating large areas, and it is slightly more laborious to use than the above two.
Precautions for Using Derma Roller
After learning the question, Which Derma Roller Size Is Best, there are some other suggestions which we should pay attention to.
Cleaning and disinfection are the first priority: the derma roller should be thoroughly disinfected with 75% alcohol before and after each use to avoid bacterial infection. Ensuring the sterility of the roller is the first step in the operation.
During microneedling treatment: do not repeatedly rotate back and forth in the same place many times, roll evenly on the whole face, and avoid too many small wounds in the same place, resulting in slow healing.
Postoperative skin care cannot be omitted: after the operation, you can use a mild repair essence or a special repair mask to achieve the effect of reducing swelling and relieving pain.
Maintain the frequency of use: too frequent use will damage the facial barrier and cause irreversible damage to the skin.
Replace the roller regularly: It is generally recommended to replace the derma roller with a new one after 4-6 uses to ensure that the needles are sharp and hygienic.
