Advanced 810nm diode laser with built-in cooling delivers fast, comfortable permanent hair reduction for virtually all skin types.
Understanding the Hair Removal Struggle
Unwanted body and facial hair affects millions of people, turning daily grooming into a time-consuming burden. Shaving causes razor burn, stubble, and irritation within hours. Waxing is painful and temporary, lasting only weeks before regrowth begins. Many people spend hundreds of hours and thousands of dollars over their lifetime on hair removal methods that never deliver permanent results. Ingrown hairs, dark spots from repeated irritation, and the constant planning around hair growth cycles leave you feeling frustrated and self-conscious -- especially during Michigan's warm-weather months when skin is most visible.
DiolazeXL laser hair removal breaks the cycle by targeting hair follicles at the root with concentrated 810nm diode laser energy. The laser selectively heats melanin in the hair shaft while InMode's built-in sapphire cooling tip protects the surrounding skin, disabling the follicle's ability to produce new hair. Using the largest spot size in its class, our team can treat large areas like legs and back quickly and efficiently. After a series of treatments, patients experience dramatic, long-lasting hair reduction -- freeing you from razors, wax strips, and the daily grooming routine for good.
The Science of Permanent Hair Reduction
DiolazeXL is an FDA-cleared 810nm diode laser system by InMode designed specifically for permanent hair reduction on the face and body. It features one of the largest treatment spot sizes in its class -- measuring 10mm by 28mm -- combined with a built-in sapphire contact cooling tip that protects the skin throughout treatment. This combination of high peak power (up to 3,000 watts) and advanced cooling allows for safe, effective treatment across virtually all skin types, including Fitzpatrick skin types I through VI with proper settings.
The laser works through a process called selective photothermolysis, where the 810nm wavelength is absorbed by melanin in the hair shaft. This concentrated light energy converts to heat, traveling down the hair to the follicle and damaging the growth cells responsible for producing new hair. Because the laser targets melanin specifically, surrounding skin tissue remains unaffected. The sapphire 3PC (Pre-cooling, Parallel cooling, Post-cooling) tip maintains a comfortable skin surface temperature throughout the pulse, preventing burns and minimizing discomfort. Clinical evaluations of 810nm diode lasers demonstrate an average hair reduction of approximately 70% at three- and six-month follow-up intervals.
Hair grows in three phases: anagen (active growth), catagen (transition), and telogen (resting). The laser is most effective during the anagen phase when melanin concentration is highest and the hair is fully connected to the follicle. Because only 20-30% of hair is in the anagen phase at any given time, a series of approximately eight treatments spaced four to eight weeks apart is needed to catch each hair during its active growth cycle and achieve optimal permanent reduction.

DiolazeXL Laser Hair Removal
DiolazeXL Laser Hair Removal
Most patients notice hair shedding beginning one to two weeks after their first DiolazeXL session. Visible hair reduction becomes increasingly apparent with each subsequent treatment, with optimal results typically achieved after approximately eight sessions spaced four to eight weeks apart. Results are long-lasting, with most patients experiencing permanent hair reduction of 70% or more. Individual results vary based on hair color, skin type, hormonal factors, and the treatment area.

Finding Your Best Results
DiolazeXL laser hair removal is ideal for adults who want a lasting solution to unwanted body or facial hair without the ongoing maintenance of shaving or waxing. During your consultation, our team will evaluate your skin type, hair color, and treatment goals to create a personalized laser hair removal plan.
Unlike older laser systems that were limited to lighter skin tones, DiolazeXL's advanced 810nm diode platform with sapphire cooling can be safely calibrated for Fitzpatrick skin types I through VI. Our team adjusts the energy settings, pulse duration, and cooling parameters specifically for your skin tone to ensure safe, effective treatment. All candidates undergo a thorough skin assessment and test patch when appropriate before beginning their treatment series.

What to Know
The most common side effects include temporary redness, mild swelling, and a warm sensation in the treatment area immediately following the session. These reactions are a normal skin response to laser energy and typically resolve within a few hours to one day. Some patients experience mild follicular edema -- slight bumps around hair follicles -- which indicates effective energy absorption and usually fades within 24 hours.
Less common effects include temporary hyperpigmentation or hypopigmentation (changes in skin color), which occur more frequently in patients who have sun exposure before or after treatment. Blistering is rare, occurring in fewer than 1% of treatments when proper protocols are followed. Paradoxical hypertrichosis -- stimulation of new hair growth near the treated area -- is an uncommon occurrence reported in a small percentage of patients, typically in areas with fine vellus hair.

Your Questions Answered
Most patients require eight treatments spaced four to eight weeks apart for optimal permanent hair reduction. The exact number depends on the treatment area, your hair color and thickness, skin type, and hormonal factors. During your consultation, our team will evaluate your specific situation and recommend a personalized treatment plan.
Most patients describe DiolazeXL as significantly more comfortable than other laser hair removal systems and far less painful than waxing. The built-in sapphire 3PC cooling tip maintains a comfortable skin temperature throughout treatment. Most patients feel a brief warm snap with each pulse, similar to a light rubber band flick, which is very manageable.
Yes, DiolazeXL can be safely used on Fitzpatrick skin types I through VI when properly calibrated. The 810nm wavelength and adjustable parameters allow our team to customize settings for your specific skin tone and hair characteristics. A test patch may be performed for darker skin types to confirm optimal settings before your full treatment.
Yes, shaving is allowed and encouraged between sessions because it removes the hair shaft above the skin without disturbing the root. However, you must not wax, pluck, thread, or use depilatory creams between treatments, as these methods remove the hair root that the laser needs to target during your next session.
Treatment times depend on the area being treated. Small areas like the upper lip or underarms take approximately 15 minutes, while larger areas like full legs or back may take 30 to 45 minutes. DiolazeXL's large spot size allows it to treat areas significantly faster than many competing laser systems.
DiolazeXL and waxing should not be performed on the same treatment area simultaneously, as waxing removes the hair root needed for laser targeting. However, you can use waxing on different body areas while undergoing DiolazeXL treatments on others. Our team can create a comprehensive hair removal plan that incorporates both options.
DiolazeXL is FDA-cleared for permanent hair reduction, meaning it significantly and permanently reduces the total number of hair follicles in the treated area. Clinical data shows approximately 70% hair reduction after a complete treatment series. Some patients may need occasional maintenance sessions once or twice per year to address any hormonal hair regrowth.
Laser hair removal is considered a cosmetic procedure and is typically not covered by medical insurance. We offer flexible financing through Cherry to make treatment accessible and affordable for all budgets.
