Ellipse Hair Removal: the clinical proof

Hair Removal is the basis for many clients seeking Intense Pulsed Light treatment. For the clinic owning the equipment, it is equally important to know that the system used removes hair, and that it stays away.

Hair removal with second generation broad spectrum intense pulsed light source – a long-term follow-up. Agneta Troilius et. al (Journal of cutaneous laser therapy 1999; 1: 173-178)

The first published study by Ellipse investigated the bikini line hair of 10 Swedish patients. A hair count was made before, 4 months (1 hair cycle) after and 8 months (2 hair cycles after) 4 treatments (1 month between treatments).

Troilius Study

Before and 8 months after 4 treatments

The study showed hair reduction of 75% at 4 months and 80% at 8 months

Hair reduction using a new intense pulsed light irradiator and a normal mode ruby laser. Peter Bjerring et al. (Journal of cutaneous laser therapy 2000; 2: 63-71)

In 2000, use of ruby laser for hair removal was the norm, and this study found that 93.5% of patients treated with Ellipse I2PL achieved measurable hair loss, compared to only 55% with the ruby laser.  Figures for both systems were lower than  would now be expected, as treatment parameters and intervals have evolved in the subsequent 13 years.

Comparison of different methods of photo epilation. S. Strangl et al. ( Med. Laser Appl. 17: 349 (2002))

An interesting German study that compared Ellipse 2nd generation Intense Pulsed Light with a first generation system (ie the effect of dual mode filtering) and with Diode and Alexandrite lasers. Various body sites were treated with each system. “The best results were obtained with the second generation  IPL system Ellipse”

Photoepilation results of axillary hair in dark-skinned patients by intense pulsed light: comparison between different wavelengths and pulse widths. Jong Hee Lee et. al. (Dermatol Surg 2006; 32: 239-245) 

Jong Hee Lee study

A Korean study comparing the HR and HR-D applicators  when treating axilla. The HR-D gave an average clearance of 83%, with no side effects.

Hair removal with Ellipse Flex intense pulsed light system. Zeng et. al. (Chinese Journal of Aesthetic Medicine. Nov. 2006. Vol.15. No.11)

A huge study of 365 patients, that showed the HR applicator to remove and average of 96% of hair after 3-7 treatments.

Hair removal of hirsutism caused by endocrinological disease or drug induced – a retrospective study of 253 patients. Lo Rumar et al. (EADV 2008)

An interesting Swedish study that looked at hair removal in various groups of “problem” patients, transsexuals, those with hormone problems (including Polycystic Ovary Syndrome – PCOS – and those whose hirsutism was caused by medication. The number of treatments required to get results is naturally higher, but the study concluded that (Ellipse) IPL was equally as effective in patients with hormonal problems as those without.

Intense pulsed light photoepilation turns out to be permanent at 5-9 years follow-up. Peter Bjerring, MD et al. (White paper, 2011)

Hair reduction with intense pulsed light – is it permanent? – a 5-10 years follow-up investigation gives the answer. Peter Bjerring, MD et al. (22nd World Congress of Dermatology, Seoul, Korea, 24-29 May, 2011)

Two papers on a very long term follow-up study (5-9 years after treatment) ended, that found only very modest regrowth after this time, and concluded that treatment could be considered as permanent hair removal.
