INTERVENTION: Patch test on forearm will be performed in all patients before starting treatment to check the sensitivity. Site of burn in the enrolled patients will include either cheek or forehead and total area (cm2) on each of above mentioned sites will be divided into two equal halves; one for tranexamic acid mesotherapy (maximum 5cm2) and other for glutathione mesotherapy (maximum 5cm2). Flip coin method will be used to decide which site and which half to be treated with tranexamic Acid or glutathione. Gentle cleansing of the affected area will be done Tranexamic acid is available in 500mg/5ml formulation, 1ml (100mg) of tranexamic acid will be taken and diluted in 10ml of 0.9% N/S i.e. 10mg/ml.This 10mg/ml of diluted formulation will be used for mesotherapy. intradermally 1cm apart to the selected site using 1cc disposable syringe with 4mm depth 30G needle.4mm depth of intradermal injection will be controlled manually by the researcher on specific area of face. Maximum dose of tranexamic acid microinjections will not exceed 12.5 mg/5cm'. Glutathione is available in 600mg powder formulation and will be prepared by dissolving in 5ml of distilled water. 1ml (120mg) of glutathione will be diluted in 10ml of 0.9% N/S i.e. 12mg/ml.This 12mg/ml of diluted formulation will be used for mesotherapy. Multiple microinjections, each 0.05ml (0.6mg) will be given intradermally 1cm apart to the selected site using 1cc disposable syringe with 4mm depth 30G needle. Maximum dose will not exceed 15mg/5cm2. All patients will be kept under observation for 20-30 minutes after each session to address any side effects (bruising, bleeding, pain etc.) and they will be advised to apply sunscreen of SPF 50 on whole of the face before sun exposure. After initial treatment session, patients will undergo six more treatment sessions with the same protocol at the interval of 2 weeks ( 2, 4, 6, 8, 10,12 weeks) and follow-up will be done monthly after the last session i.e. 4th, 5th and 6th month. Final assessment will be done at 6th month. All clinical dermatoscopic photographs will be taken with Nikon D810 digital camera with dermlite 3 dermoscopy lens before the start of treatment, at each treatment session and then at each follow-up in same pre-settings, light and from same distance.
NCT07133204
The aim of this study is to evaluate the efficacy of a topical cream infused with Scutellaria baicalensis extract in reducing hyperpigmentation on the face.

NCT05165524
The treatment of leg veins and varicosis with sclerotherapy is one of the most frequently performed medical intervention in the western world. The most common local side effects of this treatment are hyperpigmentations caused by hemosiderin deposition in the skin as well as post inflammatory hyperpigmentation. Although skin hyperpigmentation after sclerotherapy is a common over several months up to years lasting side-effect with a strong aesthetic impact, scanty data exist about treatment options. Quality-Switched (QS) lasers are efficient in the removal of exogenous and endogenous pigments, such as tattoos as well as epidermal and dermal melanin deposits. The laser light is absorbed by pigment particles, leading to a fragmentation of these particles by a photothermal and photoacoustic effect. Smaller particles can be then phagocyted by macrophages, and transported via the lymphatic system into the lymph nodes. Furthermore, the positive effect of QS lasers in the management of cutaneous siderosis in stasis dermatitis and after sclerotherapy has been described in several cases. Triple cream including hydroquinone, tretinoin and a topical corticosteroid (eg dexamethasone), is the first line therapy in the treatment of post inflammatory hyperpigmentation. This randomized controlled study aims to evaluate the efficiency of two well-known depigmentation methods (QS laser and triple cream) for treatment of post sclerotherapy hyperpigmentation, compared with a control group performing no treatment.

NCT06213987
The goal of this randomized intra-individual design with a split-side axillary approach is to comparing the efficacy of 0.025% tretinoin cream against a cream-based formulation in the treatment of axillary hyperpigmentation associated with acanthosis nigricans. The main questions it aims to answer are: * The efficacy of 0.025% tretinoin cream and cream based in the treatment of axillary hyperpigmentation associated with acanthosis nigricans. * The safety of 0.025% tretinoin cream and cream based in the treatment of axillary hyperpigmentation associated with acanthosis nigricans. Participants were randomly assigned to apply both 0.025% tretinoin cream and the cream-based product on opposing sides of the axillary region.

NCT05206318
Post-inflammatory hyperpigmentation is a common pigmentary skin disorder that is refractory to treatment. The treatment for postinflammatory hyperpigmentation is limited. Recent studies have shown that the topical skin care product cysteamine cream has a significant decrease in melanin index without obvious side effects in other dark spots such as melasma. The goal of this study is to determine the safety and efficacy of topical cysteamine in the treatment of post-inflammatory hyperpigmentation.
NCT04704245
Subjects were randomly assigned to groups for treatment with either an EGF-containing ointment (the study group) or the vehicle alone (petrolatum; the control group). The EGF ointment included recombinant human EGF (1 μg/g). Random numbers used for assignment to groups were provided by the randomization function of SAS. The subjects received one session of laser treatment with a Q-switched (QS) 532-nm Nd:yttrium aluminum garnet (YAG) laser of their solar lentigines after enrollment. . The end point of laser treatment for lentigines was immediate whitening. The subjects then applied the EGF ointment or vehicle twice daily (morning and evening) to the lesion for 4 weeks after laser treatment.
