The RF device and the Iris 1450nm device should be operated at least 24 hours apart.

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.

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.

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.

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 mainly targets melanin, reaching the lower and middle dermis layers. 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.

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, with only a small increase in type III collagen.

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 prevent sun sensitivity when used correctly with SPF 30+ sun protection, as noted in manuals and on 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.

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.

The main efficacy of Iris 1450nm is to reduce fine lines and wrinkles through collagen regeneration, eliminate acne marks, shrink pores, brighten the skin tone, and regulate uneven 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 755nm, 1064nm or 1927nm.

First, you need to determine if the melasma is in a stable phase. For example, has the existing melasma worsened after sun exposure? If not, you can try the first setting on an area without melasma and observe the results.

The primary benefit of Iris 1450nm is to reduce fine lines and wrinkles through collagen regeneration, eliminate acne marks, shrink pores, brighten the skin tone, and even out skin color. It is not mainly intended for treating pigmentation problems, especially melasma. However, it can help achieve a brighter complexion by stimulating collagen production and improving the appearance of sunspots, freckles, and epidermal melasma.

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.

Iris 1450nm can remove acne marks and scars(depth ≤200μm). 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.

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.
