What if hyaluronic acid serum (topical use) is injected in forehead linear scar instead of HA fillers?

Hello,  HA dermal fillers are sterile products specifically formulated for injection under the skin.  HA serums are liquids. If you inject the liquid if will be absorbed in a few minutes, it is also not sterile and will cause infection and severe complications.  Please DO NOT do it. Please speak to a professional and only use high quality products for your face.  One cheap product can ruin your face for life!  Hope this helps. Serums are for topical use only. Best, Dr.Avaliani

Injectable fillers are formulated to be safe for injection. Serums are formulated to be applied topically. Always consult with a physician to get a personalized plan, have treatments performed in-office, and go home with a complementary regimen. If you are looking for an at-home topical hyaluronic acid serum, we recommend SkinCeuticals H.A. Intensifier. This product is a multi-functional serum proven to amplify and maintain skin’s hyaluronic acid levels. Hope this helps.

I would not suggest injecting yourself with a product to save money. It could likely lead to an infection as your body will react to it as a foreign substance , it would have limited duration of effects if any at all. It has no cross linking for stability or G prime required by other FDA approved fillers.
