Breaking the Barriers in Acne Clearance with IPL

When treating acne, time is of the essence. LHE works fast, offering a complete treatment in 30 days. LHE's addition of heat intensifies the chemical process and decreases overall treatment time. Patients often look and feel better within 2 weeks of starting treatment. In clinical trials LHE has demonstrated up to 90% clearance of acne lesions after a 4 week treatment course with bi-weekly treatments.

LHE Acne Phototherapy

Propionibacterium acnes synthesize and store a large amount of porphyrins. Once the porphyrin is exposed to visible light it becomes chemically active and transfers to an excited state, resulting in the formation of singlet oxygen, which combines with cell membranes to destroy P.acnes. This process is dependent on the rate of production of excited porphyrins, the concentration of photons, the temperature and the wavelength of the photons. LHE acts as a catalyst to produce the required photochemical reaction from porphyrin activation to oxygen production. This ability is based on three controlled parameters, those of wavelength, overall concentration of photons and temperature.

Wavelength: Although porphyrin is thought to be most reactive to wavelengths in the 400-430nm, the blue spectrum does not penetrate as well as other wavelengths. Often, not enough protons reach the target. To optimize the tradeoff between the penetration depth required and porphyrin activation efficacy, LHE utilizes a higher range of the light spectrum including green, yellow and red.

Photons: This offsets the loss in absorption with a more direct targeting of actual porphyrin. More photons reach the target and less photons are wasted at ineffectual depth penetrations.

Temperature: The Arrhenius equation describes the rate of production of excited porphyrin molecules as a function of temperature. For most chemical reactions, elevating the temperature by 10°C will double the speed of the reaction. By combining direct heat with the light pulse, LHE further raises the temperature inside the follicle affecting a much faster chemical reaction time than light alone would generate. The generated heat also aids in reducing inflammation, opens pores and soothes the pain often associated with acne.

How LHE Acne Phototherapy Works

	Light is drawn to the melanin in the hair, raising the temperature of the hair follicle.
	LHE clears acne safely and effectively with a series of concentrated pulses of light and heat. The green wavelength light penetrates deep into the skin to cause an increase in porphyrins, resulting in the destruction of P .acnes.
	The red wavelength produces anti-inflammatory results. The addition of heat, unique to LHE, increases the effectiveness by opening the skin pores and promoting a faster chemical reaction.

Science Behind Acne

• Hormonal changes increase sebum production in the hair follicle, resulting in a blocked pore. This creates an anaerobic (oxygen-free) environment.
• Propionibacterium acnes (P. acnes bacterium), the main cause of acne breakouts, is an anaerobic bacteria and thrives in reduced oxygen environments. As the P. acnes bacteria reproduces, it produces compounds called porphyrins.

Light Treatment

• Green light causes the porphyrin molecules to release lone oxygen radicals. The oxygen radicals attack the P. acnes and destroy it.
• Red light produces anti-inflammatory results and reduces swelling. The additional heat intensifies the process and gently opens the pores to release the clog and soothe the inflammation.
