Treatment-related problems are considered to be normal in IPL treatments and in thisstudy included skin reactions following treatment up to and including severe erythema in hair removal, mild to normalerythema in acne cases and darkening of pigmented areas or temporary crusting. In the case of pigmentation treatments,temporary crusting of epidermal lesions, which sloughs off within 7-10 days during normal washing was distinguished fromtransient hyperpigmentation that lasted several weeks to several months and was considered a true side effect.T. Alster reported a significant incidence of side effects [25] in darker skin phototypes following laser treatment andrecommended prophylactic application of SPF30+ sun screen initiated at least three to four months before laser surgery toavoid post-inflammatory hyperpigmentation. No such precautions were taken in this study when using IPL therapy.Normal side effects No. Patients (%) No. incidents Av. pain score Areas Side effect(s)Acne 5 (14.3) 5 39.8 Face Mild erythemaHair removal 12 (28.8) 17 45.5 Face Mild erythemaPigment 20 (33.9) 21 46.6 Face, thigh (1), chest (1) Mild erythemaTrue side effectsAcne 0 (0) 0 n/a n/a n/aHair removal 3 (5.7) 5 47.5 Face, legs (1) Burns (1), erythemaPigment 2 (3.7) 3 48.7 Face Burns (1), erythema (2)The standard descriptions of side effects used in this study by the expert clinical assessor were graded as follows:Hair Removal:Table 5—Side effects0 = None,1 = Mild Erythema,2 = Erythema (e.g. Perifollicular Oedema),3 = Severe Erythema,4 = Crusting (eg. including transient hyperpigmentation),5 = Severe Superficial Burns (eg. including hypopigmentation).8
Acne:0 = None,1 = Mild to Normal Erythema,2 = Hyperpigmentation,3 = Severe Superficial Burns.All acne patients showed a reduction in the number of inflamed lesions with no side effects. The reduction of acne spotsobserved was similar to results reported in the literature for lighter skin types treated with IPL.Pigment:0 = None,1 = Mild to Normal Erythema / darkening of pigmented lesion / crusting,2 = Hyperpigmentation,3 = Severe Superficial Burns,4 = Hypopigmentation.Normal erythema was only seen in about one third of patients suggesting an over-cautious approach. Side effects wereseen with increased fluence. Two cases of post hair removal treatment burns were reported. The consequentialhyperpigmentation resolved in both of these cases within 3 months (See figures 7-9).PainPain experienced by the patients during all of the treatments was graded using a blank visual analogue scale (0 = no painat all and 10 = worst pain imaginable). Average pain scores for hair removal, acne and pigmentation were 4.5, 4.7 and 4.2respectively. Most subjects found the level of discomfort easily tolerated and no subjects felt the pain was unbearable as noscores were recorded above 7.0 (See figure 10).9
