What side effects should I watch for with GHK-Cu serum?
Short answer
GHK-Cu serum may cause skin irritation or an allergic reaction to an ingredient. Watch for redness, itching, burning, rash, or swelling. Safety data for compounded topical GHK-Cu are limited. Stop use and contact your physician for a concerning reaction. Seek emergency help for trouble breathing or throat swelling.
Skin irritation and allergic reactions are possible with GHK-Cu serum. Watch for redness, itching, burning, a rash, or swelling where you apply it. A reaction could come from GHK-Cu or another ingredient in the serum. Reliable side-effect rates for this compounded formula are not established.
Stop using the serum and contact your prescribing physician if you develop a concerning reaction. Do not assume burning or a rash means the product is working. Tell your care team when the reaction began, how much you applied, and what other products you used that day.
Seek emergency care for trouble breathing, throat swelling, fainting, or a rapidly worsening reaction. These symptoms need urgent assessment rather than an online message or a change in your skin care routine.
Share any history of skin allergies or sensitive skin before treatment. Compounded medications are prepared by a licensed pharmacy for one patient and are not FDA-approved. FDA does not review compounded drugs for safety, effectiveness, or quality before they are marketed.
