What could be the cause of non-itchy red rashes on my torso? (photos)

It appears that you are experiencing eczema that is not responding to your moisturiser regime. These are a couple of steps you can try to improve your condition: 1. Emollients You can consider using a water-based one like Cetaphil as the base moisturiser, and then add on a protective oil-based moisturizer like paraffin. This is particularly important for cold, dry climates. 2. Exfoliation A very gently done exfoliation with a sponge can help remove the keratinised layer of skin, and improve the moisturising effect of the emollients. Don’t overdo it. Once a week is safe. 3.

Sorry to hear that your skin rashes are breaking out all over. Sandfly or insect bite reaction is due to a hypersensitivity response of your body to the insect bites. In susceptible individuals, the body mounts a hypersensitive or ‘allergic’ response to the foreign protein deposited in the skin from the bite. The reaction can persist for weeks to months after the initial insect bite. People with atopy (ie asthma, eczema or allergic rhinitis/sinus) may be more susceptible to insect bite reactions.
