Why Choose Luowei Medical Aesthetics Clinic for Laser Hair Removal in Nanjing
Different skin tones, hair types, and body areas require different devices — using the wrong one can mean zero results, or worse, burns and pigmentation changes. Our approach is built on a multi-device clinic, Fitzpatrick-based safety profiling, and physician-grade standards.
Multiple devices available
Diolaze / Soprano XL SHR / AI BBL HEROic / Fotona Nd: YAG Covering a full range of skin tones and body areas, we select the device based on your specific profile — not a one-size-fits-all approach “One device for all”.
Safe classification across all skin tones
For deeper skin tones, 1064 nm Nd: YAG is the preferred choice; for sensitive individuals, SHR is recommended — both approaches help avoid the burns and post-inflammatory hyperpigmentation (PIH) that conventional lasers can cause on darker skin.
Medical clinic standards
Physician-supervised and performed by trained technicians, with parameters individually calibrated to your skin tone and hair type — a meaningful distinction from the fixed settings used at beauty salons.
High efficiency for large areas
High-energy diode laser with a large spot size — ideal for legs, back, and full-body treatments, delivering efficient, time-saving results over large areas.
Comfort-first approach
SHR Gliding motion combined with contact cooling makes treatment virtually painless, even in sensitive areas.

What Is Laser Hair Removal?
Laser hair removal works by having laser energy absorbed by Melanin within the follicle absorbs The absorbed energy is converted into heat, impairing the follicle’s ability to regenerate and achieving long-term hair reduction. Because the process relies on melanin absorption,Contrast between hair color and skin tone The choice of device wavelength directly determines both efficacy and safety.
Hair follicles cycle through three phases: anagen (growth), catagen (regression), and telogen (resting).Only follicles in the active growth phase Follicles rich in melanin can be effectively targeted by laser energy — which is why multiple sessions spaced according to the hair growth cycle are necessary.
Different devices operate at different wavelengths and penetration depths: 808–810 nm is well-suited for large areas and standard skin tones; 1064 nm (Nd: YAG) penetrates deeper and is safer for darker skin tones; SHR (Super Hair Removal) uses repeated low-energy pulses to maximize comfort and safety.
Key Points
- How It Works Melanin absorbs laser energy → heat destroys the follicle
- Duration of results Only follicles in the active growth phase respond to treatment (multiple sessions required)
- Realistic goals 70–90% Permanent hair reduction
- treatment 6–10 sessions, spaced 4–8 weeks apart
- Maintenance 1–2 sessions per year after completing the initial course
- Recovery period Minimal to none; normal activities can be resumed right away
How to Choose Among the Four Devices?
| Device | Wavelength / Key Features | Best suited for |
|---|---|---|
| Diolaze | 808nm Diode · high energy | Large areas, coarse hair, efficiency |
| Soprano XL SHR | 810nm In-motion heat accumulation | All skin tones, sensitive areas, pain-sensitive clients |
| AI BBL HEROic | Sciton BBL Broad-spectrum light | Hair removal + skin rejuvenation combination |
| Fotona Nd: YAG | 1064nm Deep penetration | Deeper skin tone, coarse hair |
The key to device selection is your skin tone, hair thickness, and treatment area.
How Laser Hair Removal Works
Laser energy is absorbed by melanin in follicles that are actively in the growth phase, converting to heat that disables the follicle’s ability to regenerate. Multiple sessions timed to the hair cycle are required, and the correct wavelength must be matched to your skin tone for safe treatment.
Consultation & Skin Tone / Hair Assessment
We assess your Fitzpatrick skin type, hair thickness and color, and treatment area to select the most appropriate device and wavelength.
Shaving & skin preparation
Shave the treatment area beforehand (this preserves the follicle while removing the surface hair shaft), wear protective eyewear, and confirm there has been no recent sun exposure.
Laser delivery + cooling
Laser pulses are absorbed by melanin in the hair follicle, disabling it at the root. Contact cooling or SHR in-motion gliding simultaneously protects the epidermis and enhances comfort throughout the treatment.
Hair shedding
Treated hairs gradually shed over 1–3 weeks, some appearing as “Paradoxical regrowth” shed naturally afterward.
Repeat each cycle
Sessions are spaced 4–8 weeks apart to target the next cycle of follicles entering the active growth phase, progressively building hair reduction with each visit.
Safe hair removal on deeper skin tones depends entirely on the right wavelength selection
Darker skin contains more epidermal melanin, meaning standard wavelengths risk inadvertently damaging the epidermis, causing Burns and post-inflammatory hyperpigmentation (PIH). The safe approach is to use 1064nm Nd: YAG or SHR, with energy levels adjusted downward according to skin tone.
Fitzpatrick Classification
Wavelength and energy are selected based on skin tone; 1064nm is used for deeper skin tones
Epidermal cooling
Contact cooling and SHR gliding modes protect the epidermis and reduce the risk of burns
Avoid recent sun exposure
Treatment should not be performed on recently tanned skin, to reduce the risk of pigmentation and burns
Am I a Candidate for Laser Hair Removal?
Most people are good candidates, but laser hair removal is ineffective on very light hair, and deeper skin tones require careful device selection. Suitability and device choice are determined during your consultation.
You may be a good candidate if…
- Hair is black or dark brown (melanin-containing)
- Seeking long-term hair reduction and freedom from frequent shaving
- Underarms / bikini / legs / back / facial hair
- Deeper skin tones (1064nm or SHR can be used safely)
- Razor-induced folliculitis and ingrown hair concerns
- Able to complete multiple sessions on schedule
Treatment is not recommended or requires assessment if you have any of the following…
- Light-colored hair (blonde / white / grey) — laser is ineffective; electrolysis is required
- Recent intense sun exposure or visibly tanned skin
- Pregnancy (recommended to wait until after delivery)
- Active infection in the treatment area / active herpes simplex outbreak
- Oral Accutane use within the past 6 months
- Photosensitizing medications not yet discontinued

Pre-Treatment Instructions · Treatment Process · Post-Treatment Care
Proper pre-procedure shaving and post-procedure sun protection are essential to safe, effective laser hair removal.
Pre-Procedure Preparation
- Avoid sun exposure and self-tanning for 2 weeks before treatment
- Shave the treatment area the day before your session (do not wax, tweeze, or use depilatory creams — the follicle must remain intact)
- Discontinue exfoliants and retinoids in the treatment area for several days beforehand
- Disclose any photosensitizing medications, history of Accutane use, and current skin conditions
During the treatment
- Wear protective eyewear
- A sensation similar to a rubber band snap (SHR is virtually painless)
- Contact cooling and gliding motion simultaneously protect the epidermis
- 10–45 minutes per session, depending on the area
Post-treatment care
- 48 hours of treatment, avoid hot showers, saunas, and activities that cause heavy sweating
- Apply SPF 50+ sunscreen daily and avoid sun exposure for 2 weeks post-treatment
- Treated hairs shed naturally within 1–3 weeks; gentle exfoliation can help the process along.
- Do not pick, scratch, or tweeze; shaving is the only permitted hair removal method between sessions
- Temporary redness and mild swelling around hair follicles are normal responses
Timeline After a Single Session
| Duration | Status |
|---|---|
| D0 (same day) | Peri-follicular redness and mild swelling, resolving within a few hours; diligent sun protection is required |
| D1–D3 | Redness subsides and you may resume normal activities; avoid heat and excessive sweating |
| D7–D21 | Treated hairs gradually shed (“Paradoxical regrowth” then shed) |
| 4–8 weeks | A new cohort of follicles enters the growth phase — proceed with the next session |
