For example, wounds with a heavy bacterial load may do better with an antibiotic cream such as silvadene (silver sulfadiazine) while insect bites might need an antipuritic/antiinflammatant agent. Your doctor should be able to help you make individualized choices. ...Read more

If you haven't seen an insect bite him and in particular if this is a recurrent rash it's unlikely to be an insect bite. Eczema or allergic dermatitis are commonly associated conditions. See your pediatrician. ...Read more

Wedding ring rash back after cleared & rings cleaned. Not itchy. Starts with what looks like insect bite & sporadic rash around area. Fungus? Allergy?

Possible allergy: It sounds like you have wedding ring dermatitis as you are possibly allergic to a metal component of your wedding ring. The other cause is soap that gets stuck under the ring band. If the rash is isolated to the area where the ring touches your skin then it is most likely an allergic reaction. If you have similar looking rashes other areas, possibly other causes and would need to be evaluated. ...Read more

Can cetaphil help in preventing dark scar marks from occurring from insect bites and other skin rashes?

Won't prevent scar: But it will soften the area and help make it less noticeable. Normal insect bites shouldn't scar unless scratched open if this is a problem too try putting some Benadryl (diphenhydramine) cream on and covering with band aid. If you are dark pigmented and have dark scars try fade cream but don't use it close to your eyes. ...Read more
