A case study using the Primelase diode laser highlights how advanced laser technology can deliver results for hormonal and medical-related facial hair
Laser hair removal using diode laser technology remains a highly effective modality for managing facial hair in female patients. This case by Cheryl Hanrahan from Oxford Natural Longevity & Aesthetic Clinic involved the use of the Primelase diode laser, a powerful CE-marked platform offering safe, efficient and long-term reduction of hair growth across all Fitzpatrick skin types.
Client profile
Age: 32
Fitzpatrick skin type: IV
Medical history: Polycystic ovary syndrome (PCOS)
Primary concern: Excess terminal hair growth localised to the chin
Hair characteristics: Thick, coarse, dark hair; presence of some grey hairs in the treatment zone
Clinical considerations: The presence of grey hairs was noted during the initial assessment. These were not responsive to treatment due to the absence of melanin. As diode lasers target melanin chromophores within the hair shaft, insufficient pigmentation precludes effective photothermolysis.
Treatment protocol
Device: Primelase Diode (810 nm)
Treatment area: Chin (with extension to jawline/neck based on growth patterns)
Treatment frequency: Every four weeks
Total planned sessions: 12 sessions with subsequent maintenance based on regrowth (typically around 12-week intervals)
Laser parameters (Skin type IV):
Patch test: 30 ms / 9 J/cm²
Session 1: 30 ms / 9 J/cm²
Session 2: 30 ms / 10 J/cm²
Session 3: 30 ms / 11 J/cm²
Session 4: 30 ms / 12 J/cm²
Session 5: 30 ms / 13 J/cm²
Session 6: 30 ms / 13 J/cm²
(Note: Parameters were adjusted based on skin response and patient tolerance.)
Pre-treatment protocol
The client was instructed to:
• Shave the treatment area within 24 hours prior to appointment
• Avoid all topical products (e.g., makeup, fake tan) on the day of treatment
• Cease topical prescription actives at least seven days before treatment
• Discontinue any photosensitising medications (e.g., antibiotics) in advance as appropriate All parameters and contraindications were discussed in a thorough consultation prior to treatment, and a patch test was performed 48+ hours beforehand.

Post-treatment care
Immediately post-procedure, aloe vera gel was applied to soothe the area, followed by Obagi SPF50 to protect against UV exposure. The client was advised to avoid sun exposure for a minimum of two weeks pre- and posttreatment and to use a broad-spectrum SPF50 daily.
Outcome after six sessions
The client demonstrated significant reduction in hair density and rate of regrowth, with noticeable improvement observed even after the first session. This early response had a positive impact, boosting her confidence and giving her a new lease of life – far away from her razor!
Further sessions are ongoing to achieve optimal results.
