Thank you for the enquiry.
for the possible Tinea Versicolor one should consul a dr/dermatologist, as it may be a fungus and a script would be required for either topical cream or oral tablets.
For Hyperpigmentation the following: Blemish Lotion, spray 2 x pd on affected areas, leave on. This product can be used longterm.
Blemish Repair, apply 2 x pd on the affected areas and leave on. This product should only be applied for a 6 week period, rest for 1 month and re-apply again for 6 weeks.
The Safari SPF40 sunscreen should be applied afterwards as both products make one sun-sensitive.
The Glycolic Acid will improve the texture and appearance of the skin and should preferably be applied and rinsed off (a few times per week), a while before applying the above.
