Abstract
A
ging is a physiological process which affects all body organs but when it comes to skin aging it becomes a very distressing matter, because it affects all aspects of person’s life. Skin aging occurs by combined mechanisms, intrinsic as hereditary factors or hormonal factors and extrinsic as UVR and smoking. The combination of these factors and others lead to the appearance of signs of aged skin clinically in the form of atrophy, sagging, laxity, dyspigmentation, dryness, wrinkle and telangiectasia.
These distressing signs lead to increased research in the area of preventing and treating skin aging. Skin aging treatment has become a very important concern in the recent times, many lines of treatment are available for each sign of skin aging as botulinum toxin, fillers, mesotherapy, PRP, IPL, laser etc.
Intense pulsed light (IPL) system is a high –intensity light source that emits non –coherent, non -collimated and polychromatic light in the broad wavelength range of 5oo-1200 nm.
Owing to this property, IPL is used to treat different skin problems in a variety of skin types using various optical filters. IPL was shown to be effective in skin rejuvenation and reduction of wrinkles, unwanted pigmentation and also vascular lesions. Individual light pulses are of a specific intensity, duration and spectral distribution allowing for a controlled and confined energy delivery into tissues. During the treatment, the IPL raises the temperature of the skin. The heat of skin stimulates renewal of the epidermis and increases the production of collagen.
The present study aimed to evaluate the efficacy and safety of IPL therapy in facial skin rejuvenation.
To achieve our goal, we included 21 female patients between 30 and 40 years complaining of facial photodamage signs. They were recruited from dermatology outpatient clinic of Ain Shams University Hospitals from June 2018 to January 2019. IPL was applied at 2 weeks interval for four sessions to the whole face and followed up one month after last IPL session.
All patients were subjected to full history taking, general and dermatological examination with assessment of severity of skin aging according to Glogaue scale, also photographic documentation by digital and Antera 3D camera before and one month after last IPL treatment session. Evaluation of treatment response was done according to Antera 3D camera, GAIS and patient’s satisfaction score.
Our results showed that IPL was efficient in treatment of skin photodamage as shown by significant decrease in indentation index of wrinkles, roughness index of skin texture and average melanin level measured by Antera 3D camera. Moreover, all patients reported significant improvement in facial wrinkles, texture and pigmentation.
Regarding side effects, only mild post procedure pain and mild erythema which disappeared without treatment in 1-2 hours were reported.
In conclusion, IPL is an effective, safe, non-invasive and affordable therapy for skin photodamage with minimal complications and no downtime.
