Medical aesthetics laser treatments have always been referred to as the "jack of all trades" for addressing different skin issues. So, how should you choose the laser treatment that suits your specific skin concerns?
First, let's understand the principles of laser beauty: based on the principle of selective photothermolysis, high-energy Q-switched pulse lasers are used to maximize the destruction of the "target tissue" while minimizing damage to surrounding tissues, achieving selective treatment. The "target tissue" mainly consists of melanin, hemoglobin, etc., each of which absorbs different wavelengths of lasers differently. Therefore, professional doctors use lasers of different wavelengths selectively to address various skin problems.
What are the most common skin problems that people are most concerned about? The importance of anti-aging is emphasized as we age and experience sagging skin. Irregular sleep patterns, stress, or hormonal imbalances can result in acne outbreaks. The presence of excess facial fat implies potential future sagging issues. So, which laser can improve these problems?
For initial anti-aging, using 5GMAX for firming and lifting:
Dual-wavelength (1064nm and 755nm) lasers are used to heat and firm the skin during treatment. This helps stimulate the production of collagen from within, effectively smoothing out wrinkles. It can also lift and tighten the skin. The dual-wavelength laser achieves more significant wrinkle reduction.
The 755nm laser targets skin pigments, abnormal blood vessels, hair follicles, and other skin lesions. It works on the superficial to mid layers of the skin, generating high heat that rapidly disintegrates the abnormal skin tissue. The body's immune cells then remove these tiny particles, achieving the goal of eliminating skin lesions and lightening the skin.
The 1064nm laser targets three main components: pigments, blood vessels, and water. It penetrates the skin to a depth of 4-6mm. The laser energy is concentrated in the deep layers of the dermis and subcutaneous fat, effectively heating and tightening the entire treated area. It promotes the production of type I and III collagen, significantly reducing wrinkles from the inside out, achieving firmness, rapid lifting, and facial contouring effects.
5Gmax can target three levels: the dermis, subcutaneous tissues, and the epidermis. In the dermis, it stimulates the reorganization of skin fibers, making the skin more elastic. In subcutaneous tissues, it causes fascia contraction and acts on the superficial fat layer, reducing fat and achieving facial slimming. In the epidermis, it targets hemoglobin and melanin, helping to fade blemishes and redness.
5Gmax offers five key functions: rapid lifting, wrinkle smoothing, revitalization and firming, whitening and brightening, and facial slimming and sculpting.
The secret to smooth skin, Fotona acne treatment:
What are the advantages of Fotona 4D in treating acne? First, in terms of sebum gland secretion, Fotona's acne treatment with 1064nm Nd:YAG laser can safely penetrate the skin, effectively targeting overactive sebaceous glands and reducing the risk of new acne inflammation. The Piano mode, with a pulse width of up to 5 seconds, can effectively heat the dermis and subcutaneous fat without damaging the skin, areas where sebaceous glands are located. Around 5 minutes of heating can raise the temperature in the dermis and subcutaneous tissue to 50-60°C, effectively inhibiting sebum secretion.
Secondly, regarding the overgrowth of local microorganisms, the long-pulse 1064nm laser heats the local sebaceous glands, inhibiting the proliferation of acne-causing bacteria such as Propionibacterium acnes, which has a bactericidal effect. In addition, the erbium laser's micropeeling effect effectively stimulates dermal collagen regeneration and improves skin texture.
Studies have shown that after 1064nm Nd:YAG laser treatment, acne patients experienced a significant reduction in inflammatory and non-inflammatory lesions, with lesion counts reduced by 50.06% and 15.95% from baseline to 4 weeks after treatment. The possible mechanism of action is the disruption of dilated superficial blood vessels by 1064nm Nd:YAG, leading to changes in inflammatory acne vasculature and cytokine release, including upregulation of TGF-β and downregulation of IL-8 and TLR-2, thus reducing inflammation.
For inflammatory acne: Fotona's high-power Nd:YAG laser can safely penetrate the skin to the optimal treatment depth, selectively targeting overactive sebaceous glands and blood vessels, achieving oil control, acne reduction, and redness reduction. Frac3 mode can be used to target inflammatory papules, inflammatory erythema, and post-inflammatory hyperpigmentation areas, with the endpoint being a fading of redness. Then, the Piano mode can be used for extensive heating and maintenance on areas with obvious acne, including oily or acne-prone areas, for about 5 minutes. Finally, the Superficial mode can be used for 1-2 passes on areas with blackheads, enlarged pores, post-acne erythema, and scars.
For acne scars: For treating problematic acne scars, Fotona 4D's erbium laser targets water, allowing for gentle melting of scars and skin repair. The 2940nm erbium laser in Smooth mode provides the necessary superficial surface repair with minimal penetration depth, helping to improve skin texture and discoloration. Unlike chemical peels and CO2 laser resurfacing, erbium laser surface skin repair allows precise control of penetration depth. The laser gently grinds the surface of acne scars, revealing healthy, undamaged skin below.
For acne scars with depressions, the R11 handpiece + MSP mode can be used to grind the edges of the scars to match normal skin. Then, the XLP handpiece can be used to treat the central depression, promoting skin regeneration. The Smooth mode can also be used to stimulate dermal regeneration.
Treatment frequency: According to Fotona 4D's recommended treatment frequency, treatments can be done once a month, with additional skincare and, if necessary, oral medication. If the acne is severe, the treatment interval can be shortened to 1-2 weeks based on the patient's tolerance. Patients should follow specific post-treatment care, such as avoiding hot water on the day of treatment, using masks for hydration, and using gentle cleansers and moisturizers.
Clear V-line for the jawline, Fotona fat dissolution:
Fotona 4D Pro features the Piano deep heating lipolysis mode, which tightens the dermis and reduces subcutaneous fat, resulting in body contouring and reduction of localized excess fat. This mode uses an ultra-long pulse 1064nm laser to deeply heat specific treatment areas, instantly raising the temperature to about 40 degrees. It can penetrate to a depth of 1.5-2cm below the skin's surface, directly affecting the superficial fat layer and subcutaneous fat.
Excess fat is dissolved without damaging the epidermis. It promotes the metabolism of fat deposits, producing glycerol and fatty acids. The body naturally burns these substances through physical activity, achieving body shaping and reducing localized excess fat.
In summary, when choosing laser treatments, it's essential to address your specific concerns, in order for REALR team to best help you achieve your desired goals and select the correct treatment to begin you journey.
