Hi Helen. Does this rash itch or hurt or burn?
Yes, an allergic dermatitis can create this sort of rash. If the culprit is the serum and you stop it, the rash should resolve within a week or so. Taking an antihistamine such as benedryl or claritin, and applying a mild corticosteroid cream such as hydrocortisone 1%, would help it to resolve sooner. If it does not improve, consider rosacea, which is a type of adult acne, that can also produce this sort of rash in the distribution you describe. It is very common, and can usually be managed with topical metronidazole.
You're welcome. Let me know if there is anything else I can do for you.
