When you use a product like humaworm which causes pathological organisms to die quickly and in great extent, you create a die-off effect in the body. Your liver becomes so overwhelmed with toxins that it must send some of these toxins through the skin instead of the normal elimination routes.
You should probably wait this period out before buying any topical creams. It would be like putting a band-aid on a wound and not cleaning the cut. Let the humaworm work its course (internal), then worry about the cosmetic problems.
