Share
Top 1: How does it work?
1. Does Iris 1450nm help the deeper layers of the skin? Or the surface
The MimiSilk Iris 1450nm Advanced Skin Renewing Device is designed to target the deeper layers of the skin.
Its fractional technology ensures that the highly concentrated micro-beams deliver energy precisely to the dermis layer to efficiently stimulate collagen production, while avoiding unnecessary damage to the epidermis (the surface layer).
2. How deep does the laser penetrate?
The penetration depth of the 1450nm Iris laser is 300-600 micrometers, primarily reaching the superficial to middle layers of the dermis.
3. How long should the treatment be performed on each area(Iris 1450nm)?
Our device divides the entire face into five smart zones. The duration for each zone varies depending on the setting. At the same setting, the upper lip and periorbital area have the shortest treatment times, while the forehead and cheeks take longer. The total treatment time for the full face is approximately 5 to 10 minutes. Additionally, two beeping sounds will alert you when the treatment for each zone is finished.
4. Can Iris 1450nm help skin laxity and jowls?
Yes, Iris 1450nm targets different wrinkle areas on the face and neck, including the laxity and jowls. The lifting and tightening effects are achieved through collagen regeneration over 4-8 weeks. If you are looking for immediate results, an RF device would be better. However, for long-term effects, we still recommend the Iris 1450nm.

5. Can I use around my eyes on undereye wrinkles and hooded lids? Do I need eye protection when using around my eyes? Is it safe for upper eyelid?
The device is designed with 5 scanning areas separately based on facial features:
- FOREHEAD
- PERIORBITAL(left and right)
- CHEEK(left and right)
- UPPER LIP
- CHIN
Based on your needs, you can select one or more areas to scan. Theoretically, the undereye wrinkles and hooded lid area are acceptable. For the upper eyelid, please be careful to avoid the eyeball. Although 1450nm light is invisible and no goggles are required, please do not look directly at the laser port.
6. Can Iris 1450nm be used for neck anti-aging?
Iris 1450nm is designed for facial skincare. It's FDA & CE-cleared for treating wrinkles around the eyes and has been proven safe for use on all skin areas (excluding the thyroid area), regardless of skin type or tone. Many customers have reported visible wrinkle reduction on the full face, neck, chest, and hands. We plan to pursue further FDA clearance for these additional areas to ensure broader treatment claims.
7. Can Mimisilk be used on hands and neck?
Iris 1450nm is tailored for facial skincare but can also be applied to the neck, chest, and hands. It is FDA-approved for treating wrinkles around the eyes and has been shown to be safe on all skin areas, excluding the thyroid region, regardless of skin type or tone. Many users have noted visible wrinkle reduction on the face, neck, chest, and hands. For these areas, we suggest using the FOREHEAD mode.

8. How long does it take to see results? - Iris 1450nm
Typically, noticeable effects appear within 8 weeks. The functions of controlling oil, smoothing skin, shrinking pores, and reducing fine lines usually show significant results after 4 weeks of use.
- Significant improvements in skin texture and elasticity were observed in 83% of subjects, with an average reduction of 43% and a maximum reduction of 62%.
- In 89.7% of subjects with large pores, uneven skin tone, and dark spots, the average brightening improvement was 71%, with a maximum of 87%.
- 79% of subjects experienced substantial collagen repair, with an average increase in collagen production.
- All participants with blemishes and scars showed significant reductions after use, with an average improvement of 71% and a peak improvement of 89%.
9. Why does collagen regeneration take 60 days?
The 3-Phase Timeline of Collagen Regeneration:
- Inflammatory Phase (Days 1-5),
- 2. Proliferative Phase (Days 5-21),
- 3. Remodeling & Maturation Phase (Weeks 3 to 6+ months, peaking around 60 days). This is the critical, time-consuming phase that defines the "60-day" timeline.
Aesthetic Treatments (Lasers, Microneedling, Radiofrequency): These procedures create controlled micro-injuries to stimulate this process. The peak of neocollagenesis typically occurs between 4 and 12 weeks, with "60 days" (or 8 weeks) serving as a common clinical milestone to assess initial results. Therefore, the recommended use of Iris 1450nm involves continuous application for 8 weeks, followed by a 4-week break. Then, repeat the "8+4" cycle consistently to maintain optimal skin condition over time.
10. Frequency of MimiSilk Iris 1450nm Use?
The core period involves 3-4 sessions per week, and the collagen activation process lasts 8 consecutive weeks. This helps to invigorate the skin, activate the repair mechanism, and is the crucial stage for achieving significant results.
Upon entering the 4-week rest period, use will be suspended for 4 weeks. The achievements of the core period will be consolidated to allow the skin sufficient time to recover, adjust, and avoid excessive use.
Then repeat the "8+4" cycle continuously to keep the skin in good condition for a long time.
Tips: If during the "8+4" cycle, there is an interruption of 2 weeks or more, it is recommended to restart the 8+4 cycle to ensure the regeneration effect of collagen.
11. Can I use contact gel with the Iris 1450nm device?
The home-use laser device does not require gel, as it might interfere with light output and does not help reduce pain (if there is any). Other beauty devices, such as those using radiofrequency and microcurrent, use gel to conduct electricity.
For most people, the treatment process is nearly painless. For first-time users, we recommend starting with level 1 and progressing to higher levels if tolerated. Compared to the large-spot laser, our fractional laser produces a stronger stinging sensation, especially at levels 2 or 3 for the first time. This also indicates that the device is functioning properly.
12. How does it compare with a professional fractional laser treatment vs. an at-home fractional laser treatment(Iris 1450nm)?
The highest-level Iris 1450nm laser has a single-beam energy of 12 mJ, approximately one-quarter of the energy commonly used in clinical practice, resulting in less pain but requiring longer treatment time. Therefore, strictly adhering to the "8+4" cycle specified in the operating manual is crucial.
Top 2: Iris 1450nm Laser vs RF Devices
13. Can I use Iris 1450nm with my RF device?
The RF device and the Iris 1450nm device should be operated at least 24 hours apart.
14. Does the Iris 1450nm device cause complications for a future face lift?
No complications. If you mean the RF device for a facelift, whether used in the clinic or at home, that does not damage the skin surface, you can typically use Iris 1450nm after 24 hours, as the two devices work on different principles. The RF targets the muscle layer, while the 1450nm fractional laser primarily affects the dermis.
If the invasive surgery is performed by the clinic, its effects can generally last for some time. When issues that need stabilization occur again, you can wait until there are no obvious wounds or discomfort before using Iris 1450nm.
15. How would NAFL technology be different than fractional RF?
NAFL is like a team of skilled archers (laser beams) firing arrows that create precise, deep pins of injury in a fortress wall (your dermis). The wall then repairs itself stronger at each arrow point.
Fracture RF is like a team of sappers with heated spears (microneedles). They physically penetrate deep into the wall's foundation, deliver heat, and as they pull out, they create small cracks. This damages both the wall's surface and its underlying structure, prompting a more extensive rebuild at the foundation level, which can also affect the ground (fat layer) beneath it.
In essence: Choose NAFL for excellent texture and tone improvement with no downtime. Choose Fracture RF when your main goals are tightening, lifting, and contouring, especially if you want to address excess fat.
16. What are the differences between the microneedling radiofrequency device and the Iris 1450nm laser device, and which one is better for the jawline problem?
Radiofrequency (RF) technology falls into two categories: microneedling and fractional. Microneedling is invasive, whereas fractional is non-invasive, and both are available in professional and home-use versions. Professional-grade microneedling and fractional RF energy can penetrate into the subcutaneous tissue, thereby lifting the SMAS layer and effectively reducing significant jawline laxity. This approach is more suitable for individuals over 50 with noticeable facial sagging. Microneedling RF further enhances transdermal absorption through an invasive process. However, home-use microneedling RF, due to energy restrictions, cannot reach the subcutaneous SMAS layer. While it offers immediate visible effects on the jawline, its long-term benefits are similar to fractional laser treatments: stimulating collagen regeneration to tighten and lift the skin. Additionally, home-use microneedling RF requires a higher level of user skill compared to home-use non-ablative fractional laser devices. Thorough disinfection of the environment and face is essential before using microneedling RF.
Conclusion: In the home-use device market, for significantly sagging skin, if immediate results are a priority, fractional RF technology should be the first choice, while microneedling RF is not recommended. If long-term effects are more important, Iris 1450nm and fractional RF are excellent options.

Top 3: Brand Comparison
17. Iris 1450nm vs NIRA Laser
Both of us are FDA-cleared 1450nm non-ablative lasers. Iris 1450nm is a fractional laser, while our micro-beam has a diameter of just 100 micrometers (φ = 100 μm). NIRA 1450nm is a non-fractional laser with large-spot technology, φ = 2 mm. MimiSilk Iris 1450nm delivers more energy and higher efficiency, resulting in faster collagen regeneration (our maximum energy is 2.11 J/cm² compared to Nira Pro's 2.05 J/cm²). Our device stimulates natural collagen production for a more youthful look in 60 days (8 weeks), whereas Nira previously claimed it would take 90 days.
18. 1450nm vs 1064nm Laser(dermrays revive)
The 1450nm wavelength is ideal for stimulating collagen regeneration. It mainly targets water as its primary chromophore, penetrating the upper and middle layers of the dermis. It shows the highest sensitivity to both type I and type III collagen, thereby enhancing collagen production more effectively. This wavelength not only reduces fine lines and wrinkles but also helps diminish pigmentation and depressions, tighten pores, and improve skin tone.
On the other hand, the 1064nm wavelength primarily targets melanin, reaching the lower and middle dermis. Only a small amount of its energy is used for collagen regeneration. The 1064nm laser is more effective at reducing melanin levels. Therefore, the 1450nm wavelength is more effective than the 1064nm in reducing wrinkles, controlling sebaceous activity, minimizing pore size, and decreasing acne scars.
19. Iris 1450nm vs LYMA Laser
The Iris 1450nm is an FDA and CE-approved fractional laser device. LYMA, on the other hand, combines LED (620nm) and LLLT laser (808nm) technologies, both of which are FDA-approved. The main difference between these two laser technologies is that the Iris 1450nm fractional laser promotes collagen production and regeneration through micro-injuries, while the LLLT laser enhances existing collagen through phototherapy and also stimulates some collagen regeneration, but not to the same extent as the Iris 1450nm (a non-ablative fractional laser). Furthermore, the LLLT laser primarily increases type I collagen, which is responsible for maintaining skin firmness and smoothness, while only slightly increasing type III collagen.
20. Is the non-ablative fractional laser an old technology(like Tria)? What's the different between Iris 1450nm laser with LYMA and ZIIP device?
Non-ablative fractional lasers (such as 1450nm/1440nm) remain the gold standard for anti-aging and are not outdated. They are well-validated and widely popular worldwide. Most home-use phototherapy devices, including fractional lasers, can reduce sun sensitivity when used correctly with SPF 30+ sun protection, as noted in their manuals and on their websites. These lasers may cause slight discomfort due to their technical design. Our goal has always been to improve the customer experience.
Non-ablative fractional lasers are especially suitable for users over 40 with specific anti-aging concerns.
Core Benefits: Addresses oiliness, pores, mild scars, and wrinkles.
Perception & Results: You might feel a slight tingling, but collagen regeneration and improvements in skin texture are significant and long-lasting, making this ideal for deep anti-aging.
Devices like Lyma and ZIIP work by boosting cell metabolism through stimulating ATP production, primarily improving temporary fine lines associated with early aging. They are gentle and suitable for daily use.

Top 4: Spots and Pigmentation
21. I’m looking for a device to lighten sunspots, freckles and SK(Seborrheic Keratosis)
The main efficacy of Iris 1450nm is to reduce fine lines and wrinkles through collagen regeneration, eliminate acne marks, shrink pores, brighten skin tone, and even out skin color. The main benefit is not for treating pigmentation problems such as sunspots and freckles. However, it can achieve a brighter complexion by stimulating collagen production, thereby improving the appearance of pigmentation issues such as sunspots and freckles.
However, it is not the optimal wavelength range for removing pigment deposits.
For pots on the epidermis layer, it is recommended to receive pigment treatment at a clinic using 1927nm. Additionally, our 1927nm household device is currently in active preparation. We sincerely invite you to continue following our brand.
22. Does it reduce sun pigmentation? How does the device brighten skin tone?
The main benefit of Iris 1450nm is its ability to help reduce fine lines and wrinkles by encouraging collagen growth, as well as to diminish acne scars, tighten pores, brighten skin tone, and even out skin color. While it isn't specifically meant to treat pigmentation issues like sunspots and freckles, it can still contribute to a brighter look by stimulating collagen, which might improve the appearance of pigmentation spots.
23. Does the Iris 1450nm laser avoid creating dark spots on Asian skin?
Iris 1450nm is safe for all skin tones; it's FDA-cleared, and the highest-grade single-laser beam delivers 12 mJ, approximately 1/4 the energy of in-hospital equipment, so it won't darken any skin (including Asian skin). Typically, we recommend using it in the evening and applying a moisturizing mask. When heading out the next day, make sure to apply sunscreen.
Top 5: Acne Marks
24. Does Iris 1450nm helps poc marks or post-acne marks?
Iris 1450nm can remove acne marks and scars (depth ≤ 200 μm). The effect of "deep acne scars" will weaken, and the usage period needs to be extended. The specific duration depends on the type of acne scar:
1. Effective type: such as "boxcar" and "rolling" acne scars (depth less than 200 micrometers), a slight filling effect can be seen 8 weeks later, and the effect will be more obvious 12 to 16 weeks later.
2. Limited effect type: such as "icepick" acne scars (depth greater than 300 micrometers, narrow opening, deep bottom), since the laser only acts on the superficial layer of the dermis (300 to 600 micrometers), it cannot reach the bottom of the acne scar, 8 weeks may only improve the roughness at the tip of the scar, and it needs to be extended to 24 weeks (6 months), and combined with level 3 settings (requiring skin adaptation) to see the deepening of the scar;
3. Recommendation: Users with deep acne scars can combine "clinic fractional laser" (such as 1565nm non-ablative laser), and use the home equipment as "post-treatment maintenance". This not only enhances the effect but also extends the maintenance period after clinic treatment.
25. Is MimiSilk Iris 1450nm effective in deep acne scars?
The effect of "deep acne scars" will weaken, and the usage period needs to be extended. The specific duration depends on the type of acne scar:
- Effective type: such as "boxcar" and "rolling" acne scars (depth less than 200 micrometers), a slight filling effect can be seen 8 weeks later, and the effect will be more obvious 12 to 16 weeks later.
- Limited effect type: such as "icepick" acne scars (depth greater than 300 micrometers, narrow opening, deep bottom), since the laser only acts on the superficial layer of the dermis (300 to 600 micrometers), it cannot reach the bottom of the acne scar, 8 weeks may only improve the roughness at the tip of the scar, and it needs to be extended to 24 weeks (6 months), and combined with level 3 settings (requiring skin adaptation) to see the deepening of the scar;
- Recommendation: Users with deep acne scars can combine an "in-office segmented laser" (such as a 1565nm non-ablative laser) with home equipment for "post-treatment maintenance". This not only enhances the effect but also extends the maintenance period after in-office treatment.
