Hi Loyiso, thank you for the question.
This is a difficult question to answer accurately over the internet and your best option would be to consult with a dermatologist who can examine the areas of concern and advise you on the appropriate treatment option.
From your description the darker patches may be some form of pigmentation and there are various causes:
Endocrine (hormonal changes), metabolic (renal failure, liver failure, vitamin B12 deficiency, etc.), neoplasia (advanced forms of cancer), rheumatologic (arthritis, Still’s disease, etc.), and systemic drugs
I do not know of any of the medication groups you mentioned causing pigmentory changes but one should check with your physician.
The most probable cause is sun damage or as a result of post inflammatory changes to the skin. The pigmentation can be treated and one has various options: topical regimes (glycolic acid peels with depigmenting creams), laser pigment removal and light based technology pigment removal. It is of the utmost importance that if you choose the route of technology that the area is treated by a medical doctor only trained in the use of the machine and that the technology used is safe for darker skin types. Whatever treatment modality you choose it is important to wear a SPF 30 or higher that contains zinc oxide and/or titanium dioxide.
