- Scar Removal
- Melasma Treatment
- Eye Area Skin Tightening
- Anti-Aging and Wrinkle Removal
- Dark Circle Removal
- Shrink Pores (Pore Tightening)
- Breast Lifting
- Hair Regrowth
- Oral Contraction (Face Slimming)

Real and effective application details of 1927nm Thulium laser and 1927/1550 Thulium Erbium include:
Acne Treatment
Thulium laser is very effective in treating acne. According to Liton Laser’s clinical experience and customer feedback, improving acne often only requires one treatment to achieve excellent results.
1. Before Treatment (Preparation)
Before thulium laser treatment of acne, postoperative products should be prepared in advance, including skin care products for improving acne and moisturizing. This is because thulium laser treatment can open the skin channels, so the products can be fully absorbed and better treatment results can be obtained.
CE-level glasses and eye masks are used by beauticians and patients respectively to avoid laser irritation to the eyes and protect human safety.
2. Treatment Process (Details)
During the treatment, when the beautician starts the machine, the 1927nm Thulium laser machine handpiece should be selected. For acne treatment, Liton Laser recommends using the epidermal tip in the fractional handpiece.
For the machine parameters, including power, pulse width, dot spacing, pattern, mode, etc., you can refer to the “1927nm Thulium Laser Aesthetic Treatment Guide” provided by Liton Laser. According to the guide, set the parameters appropriately. During the treatment, the whole face should be lasered twice, and for areas with severe acne, an additional single area treatment should be performed.
3. Treatment Results (Before and After Photos)

This is a before and after photo of 1927nm Thulium laser treatment for acne. Before the treatment, the patient had severe acne on her face and redness in the facial area. After the treatment, the patient’s acne was greatly reduced, and the treatment results were very obvious. And this was a one-time treatment.High-quality machines and the most appropriate treatment parameters can achieve the best treatment results.

Scar Removal
Thulium lasers are also effective for scar treatment, whether they are hypertrophic scars or depressed scars. Using micro-ablative treatments, scar removal can be done in a similar way to CO2 lasers.
1. Treatment Preparation
After the 1927nm thulium laser treatment, skin care products must be combined for treatment, so scar repair plasters or products should be prepared in advance.
Secondly, glasses and eye masks are also necessary for treatment. Since thulium laser scar removal is a minimally invasive treatment, in order to increase the comfort of the treatment, you can appropriately prepare a cold air machine (physical cooling, reducing the patient’s epidermal temperature) and anesthetics (similar to CO2 laser treatment, some patients are more sensitive to pain, so anesthetics are needed to relieve pain).
2. Treatment Details
For thulium laser ablative treatment of scars, we usually choose a large-area fractional epidermal tip handpiece. In treatment, the power and pulse width need to be larger, and the point spacing needs to be smaller to ensure that each small area has enough energy. For specific treatment parameter settings, you should refer to Liton Laser’s “1927nm thulium laser aesthetic treatment guide”. When the treatment is over, the scar should have a slight scab.
3. Treatment Results
1927 Thulium laser scar treatment usually requires 3 or 4 treatments, each with a recovery period of 2 months. After treatment, the scar will return to smooth skin.
Melasma Treatment
The treatment of melasma is also the key treatment target of thulium laser. Other pigment spots can be effectively improved by using fractional 1927nm thulium laser. But be careful to avoid the occurrence of pigmentation.
1. Preparation
There are many melasma treatment products on the market, and you can prepare a relatively high-quality one at will. In order to ensure the effectiveness of the treatment, the doctor or beautician should determine the type of melasma in advance.
From the perspective of the cause of occurrence, check whether it is pigmented melasma or vascular melasma. From the perspective of skin layers, check whether the melasma is in the dermis or epidermis.
2. Treatment Details
For the treatment of melasma, since we need to avoid pigmentation and epidermal burns, Liton Laser has prepared a fractional dermal tip handpiece. The focus of this dermal tip is on the dermis, so the energy is directly input into the dermis, and the heat is accumulated in the dermis, directly acting on the pigment cells, which can avoid epidermal burns and reduce the occurrence of pigmentation.
For the parameter settings of its treatment, you can also refer to Liton Laser’s “Thulium Laser Aesthetic Treatment Guide”, or if you have enough treatment experience, you can try more parameter values yourself. When the skin is slightly red and slightly hot to the touch, the treatment can be ended.
3. Before and After Treatment

Thulium laser treatment of melasma usually requires 4 to 5 treatments, but each treatment can make the spots lighter, thereby improving the spots.
The above pictures are photos of melasma before and after the 1927nm thulium laser treatment. Before the treatment, the patient’s melasma area and location were very obvious, and there was severe pigment accumulation at the junction. After a one-time treatment, the patient’s melasma became lighter, and the pigment accumulation problem was alleviated at the junction of the spots and normal skin. The contrast before and after the treatment is large, and the patient has achieved excellent treatment results! After more treatments, better results will be obtained.

Eye Area Skin Tightening
Thulium laser is also very effective in removing wrinkles around the eyes. It can stimulate collagen regeneration through the photothermal effect, making the skin around the eyes smooth again.
1. Preparation
Prepare a regimen containing anti-aging and skin firming repair products, and observe whether the wrinkles around the eyes are dynamic wrinkles, and then determine the order of treatment.
2. Treatment Process
In Thulium laser tightening of the skin around the eyes, Liton Laser usually recommends the use of a small area roller tip handpiece. Since the area around the eyes has dynamic wrinkles and sagging skin, the roller handpiece can also have a certain lifting effect during the heating process.
For the parameter selection and setting during the treatment, please refer to the “1927nm Thulium Laser Aesthetic Treatment Guide”. It should be noted that tightening around the eyes usually only requires two rolling treatments.
3. Treatment Results
The treatment of tightening the periorbital area usually requires long-term persistence. Due to the frequent activities in the eye area, 5 to 6 treatments are required, and the treatment cycle is also one month.

The above pictures are before and after photos of using 1927nm Thulium laser to remove fine wrinkles under the eyes and tighten the skin around the eyes. And this is the result of 1 session of treatment.
You can see that before the treatment, the client had many fine wrinkles around the eyes and the skin was loose. After the treatment, all the fine wrinkles were removed and the skin around the eyes was tightened, achieving excellent treatment results.

Anti-Aging and Wrinkle Removal
Skin rejuvenation is also one of the main functions of thulium laser. Anti-aging and wrinkle removal are key. Anti-aging treatment ranks first in beauty needs all over the world. Liton Laser’s thulium laser is also quite effective in anti-aging and wrinkle removal.
1. Advance Preparation
Before anti-aging and wrinkle removal, you should prepare anti-aging skin products, diagnose the skin condition and treatment area, and mark the areas with severe subcutaneous wrinkles and deep wrinkles, and focus on repeated treatments during treatment.
2. Treatment Process
In Thulium laser anti-aging and wrinkle removal, when choosing machine treatment handpiece, you can choose between large area roller tip and fractional dermis tip. The treatment parameters also refer to the “1927nm Thulium Laser Aesthetic Treatment Guide” provided by Liton Laser. During the treatment, repeat the treatment of the key area 3 times, and end the treatment when the skin is hot.
3. Before & After Pictures

The above picture shows an Iranian visitor trying our thulium laser at Liton Laser’s Türkiye exhibition in 2023. The patient’s skin photos at three stages: before treatment, one week after treatment, and one month after treatment.
It can be seen that the anti-aging treatment with thulium laser is very successful. Before the treatment, the patient’s skin color was dull and the facial wrinkles were obvious. After the treatment, the skin was smooth and bright, most of the wrinkles were completely removed, and some dynamic wrinkles only left shallow marks.

Dark Circle Removal
1927nm thulium laser and 1550nm erbium laser are very effective in removing pigments. In fact, dark circles are caused by the accumulation of melanin. Through the photothermal effect of thulium erbium laser, the black pigments around the eyes can be deactivated and removed through metabolism, thus achieving the effect of removing dark circles.
1. Pre-treatment Work
Before treatment, the patient should clean the facial area, and the doctor or beautician should prepare the treatment products (containing whitening ingredients such as niacinamide or arbutin) and repair products (replenishing moisture and collagen) for the treatment.
To treat dark circles with thulium laser, you should choose Liton Laser’s dermal tip thulium laser handpiece.
2. Treatment Details
Choose thulium laser or thulium erbium laser machine treatment, set the treatment parameters and mode in advance, and refer to the “Thulium Erbium Laser Treatment Guide” provided by Liton Laser. For dark circles treatment, only low-power, narrow pulse width non-ablative treatment is required.
When the patient’s dark circles become red and hot, end the treatment immediately and apply whitening skin care products to get better treatment results.
3. Before and After Photos

This before and after treatment photo shows the result of combined treatment with thulium laser and erbium laser, which successfully solved the patient’s dark circles and enlarged pores.
After 1 session of Thulium laser treatment, the patient’s skin was greatly improved. As can be seen from the above picture, before the treatment, the patient had dark circles around the eyes and very large pores on the cheeks. After the treatment, the dark circles have been removed, the skin is left slightly red, the facial pores are instantly shrunk, and the skin issues are well resolved.

Shrink Pores (Pore Tightening)
1927nm Thulium laser can be used to shrink pores. It uses the photothermal effect to shrink the collagen inside the large pores, thereby shrinking and tightening the pores. After real trials by Liton Laser, our 1927nm Thulium laser can instantly shrink pores and tighten large pores.
1. Preparation Before Treatment
Before treatment, the patient’s area with large pores should be cleaned, and in addition to moisturizing products, skin care products containing collagen should be prepared. And determine the treatment mode. If the area is small and irregular on the nose, a random treatment mode should be used.
2. Treatment Process
Using thulium laser to shrink large pores, make them tight and small, is also a basic application of thulium laser. During the treatment, it is recommended to use a fractional epidermal probe. You can choose different sizes of handpiece tip according to the area, or you can choose the treatment pattern area in the operation interface.
Usually use low power, short pulse width, and repeat the treatment back and forth until the skin is red.
3. Photos Before and After

The above picture shows a student in Liton Laser’s China Beauty Laser Training Course. She actively tried the 1927nm Thulium Laser treatment during the training. The picture shows her before and after using Thulium Laser for 1 session to tighten and shrink her pores.
It can be seen that before the treatment, this student had more pores on her nose, which were larger than ordinary pores. After the Thulium Laser non-ablative treatment, the pores shrank immediately, greatly improving the skin concern of large pores.
Breast Lifting
Thulium laser for breast enhancement is not common in the current market, but feedback from Liton Laser customers and treatment and confirmation by Dr. Hong (a famous Chinese laser training professor) proves its safety and effectiveness.
1. Preparation
Before treatment, in addition to preparing appropriate restorative products, the client should also undergo a professional diagnosis. Since the treatment area is relatively fragile, it is necessary to determine in advance whether thulium laser treatment can be tried.
2. Treatment
During the treatment, Liton Laser recommends using a dermal tip handpiece. Safety must be ensured at all times, so that energy can be concentrated in the dermis and the epidermis is safe and warm enough.
When the skin surface turns red and slightly warm, the treatment can be ended. For some patients who are sensitive to heat, a small fan or air cooler can be used to cool down.
3. Results
The 1927nm thulium laser breast lift treatment can achieve results in one treatment, but the recovery period is longer and takes three months.
Hair Regrowth
Thulium laser treatment for hair regeneration and prevention of hair loss is also valued by many customers. After continuous real-life treatments by Liton Laser, it was found that low-energy 1927nm fractional thulium laser has a positive effect on scalp care and hair regrowth.
1. Hair Growth Preparation
Before hair growth, you also need to prepare hair growth products, and if you use an LED light therapy machine, you can also use LED red light therapy for 15 minutes first.
2. Hair Growth Treatment
Thulium laser hair regeneration treatment usually uses a large-area roller tip handpiece. Rolling treatment can stimulate hair follicles and use low-power energy to provide slow thermal stimulation. Detailed treatment parameter recommendations can be obtained from Liton Laser.
During treatment, treatment should be done slowly, using random or continuous mode. Try rolling back and forth 3 times until the scalp feels warm and the client feels a slight tingling sensation, then the treatment can be ended.
3. Before and After Photo

The above picture is a before and after comparison of fractional thulium laser hair regrowth. Two months before and after the treatment, the patient’s head hair has changed greatly.
Before the treatment, the patient’s head had a large gap between the hair and the head could be easily seen, and some areas of hair were severely missing. Two months after the treatment, the patient’s hair increased significantly and the gap between the hair became smaller.

Oral Contraction (Face Slimming)
The fundamental purpose of thulium laser for oral contraction and tightening is to slim the face. Liton Laser is also the first manufacturer to try thulium laser for oral treatment, and we have achieved excellent treatment results.
1. Preoperative Preparation
Before oral treatment, rinse your mouth and check the oral condition to ensure that the patient can receive treatment normally.
2. Treatment Process
During treatment, the oral mode of thulium laser should be selected, and the oral tube handpiece should be used. To ensure cleanliness and hygiene, a medical grade set should be added to the oral tube. The treatment parameters should refer to the “1927nm thulium laser aesthetic treatment guide”. The treatment can be ended when the patient feels the heat inside the mouth and the cheeks are slightly red.
3. Final Result
Thulium laser is used for oral treatment, and better results can be seen after two treatments. Through non-invasive laser treatment, facial contours and areas can be indirectly improved, which is more suitable for patients with fat cheeks.
Vaginal Tightening
Fractional thulium laser can also be used for vaginal tightening. Its principle is similar to that of fractional CO2 laser. When thulium laser is used for high-power treatment, its treatment effect is infinitely close to that of CO2 laser.
However, vaginal tightening treatment requires professional medical knowledge. Considering the safety and professionalism of the treatment, it is recommended that beauticians and doctors who are experienced and have used CO2 laser or other vaginal tightening laser treatments use it.
