Hi..
Welcome to HEALTHCARE MAGIC..
As per your query it seems to be
hyperpigmentation causing blackish discolouration around the lips and forehead..
As the creams that you have used causes red rashes it is due to
allergic reaction to the most probable steroid component present in the creams or even the other products.
First of all let the reaction to subside, take Levocetrizine for it and do cold compresses..
Once the reaction subsides you can start using Kojic acid and
glycolic acid containing creams over the face as it is safe for long term use and also cause lightening of the dark areas..
Apply Vitamin E oil at night..
Exfoliate your skin twice a week..
Take vitamin C supplements..
For lubrication apply aloevera gel and avoid all kind of chemical cosmetics..
If you still do not find improvement you can go for galvanic facial,
microdermabrasion or
chemical peels..
Hope this information helps..
Thanks and regards..
