TREATMENT
GentleLase Pro-U Alexandrite Hair Removal
Alexandrite Laser Hair Removal: Mechanism and Operation
The Alexandrite laser operates at a wavelength of 755nm and is based on the principle of selective photothermolysis. Melanin in the hair absorbs the laser's heat energy, causing damage and shrinkage to the hair follicle, which inhibits hair growth and leads to hair shedding. Due to variations in hair thickness and growth cycles across different areas of the body, each session typically removes about 20-30% of the hair, making a full course of treatment about 4-6 sessions.
The Alexandrite laser is equipped with an intelligent cooling system, DCD (Dynamic Cooling Device), which sprays a cooling agent on the skin before treatment. This protects the epidermis from overheating or burns, eliminating the need for gel application, as is required in IPL treatments, and shortens the treatment time. The process is fast, clean, and comfortable. Additionally, the heat stimulation helps tighten pores, improving skin concerns such as uneven pigmentation and enlarged pores.
Areas Suitable for Alexandrite Laser Hair Removal
Advantages of Alexandrite Laser Hair Removal
- High Efficiency: The Alexandrite laser effectively targets melanin, allowing for quick and efficient hair removal. Fewer sessions are needed to achieve noticeable results.
- Comfort: Modern Alexandrite laser devices are typically equipped with cooling systems that lower the skin temperature during treatment, minimizing discomfort.
- Long-Lasting Results: After multiple sessions, the hair follicles are permanently damaged, leading to slower or even halted hair growth, resulting in long-term hair removal.
- Safety: Alexandrite laser hair removal is relatively safe for most skin types, with minimal side effects.
Alexandrite Laser Hair Removal Treatment Process


Pre- and Post-Treatment Guidelines for Alexandrite Laser Hair Removal
Pre-Treatment Guidelines:
- Avoid plucking hairs, as it can reduce melanin and impact treatment effectiveness or cause folliculitis, preventing laser treatment.
- Refrain from applying any irritating products, scrubs, or exfoliating creams to the treatment area for one week prior.
- If your skin is inflamed, experiencing an allergic reaction, or dry and rough, treatment should be postponed.
- Shave the treatment area clean one day before the session.
- On the day of treatment, wear loose clothing to minimize friction on the treated area post-procedure.
- Contraindications: Those who are pregnant, have darker skin tones that are sensitive to light, have sunburn or excessive sun exposure in the treatment area, or have wounds or allergic reactions in the treatment area should avoid this treatment.
Post-Treatment Care:
-
Avoid using products containing fruit acids, brightening agents, fragrances, exfoliants, or alcohol in the treated area for one week.
-
You may shower with body wash or soap, but keep the water temperature slightly cooler.
-
While there won’t be open wounds post-treatment, mild redness may occur. Applying ice packs and moisturizing lotions will help reduce it within a few hours to a few days.
-
If small black hair roots appear, they will fall out about a week after treatment.
-
Strengthen hydration and sun protection post-treatment. Avoid high-temperature environments such as steam baths, saunas, and swimming pools for a week.
With its efficiency, comfort, and long-lasting results, Alexandrite laser hair removal is an ideal choice for those seeking smooth, hair-free skin. By undergoing treatment at a professional medical clinic, patients can achieve their desired results safely and comfortably. If you’re looking for an effective long-term hair removal solution, Alexandrite laser hair removal is undoubtedly a worthy option to consider.
