What should you know about salmon DNA mesotherapy?

Mesotherapy places small injections into the skin rather than adding volume in the way a traditional filler is designed to do. Products described as salmon DNA may contain purified nucleic-acid fragments from a marine source, but the exact ingredient, concentration, manufacturing standard, and intended use vary between products. The phrase is therefore not enough to identify what will be injected.

Possible short-term effects include pinprick bleeding, swelling, redness, tenderness, bruising, or itching. Infection, allergic reactions, prolonged inflammation, or an unexpected skin reaction are less common but clinically important possibilities. Results should be described as variable rather than promised.

Ask to see the product name, ingredients, expiry information, storage details, and the clinician’s qualifications. Tell the provider about allergies, pregnancy or breastfeeding, immune conditions, active acne or cold sores, skin infection, medicines that affect bleeding, and previous reactions to injections. Avoid treatment over inflamed or infected skin. Discuss whether a regulated [Skin Boosters](/treatments/injectables/skin-booster-treatment/) option better matches your goal and what aftercare is required.

Contact the provider if redness, warmth, swelling, pain, or drainage is worsening rather than settling. Seek urgent medical help for breathing difficulty, facial or throat swelling, faintness, severe pain, rapidly changing skin colour, or vision symptoms after injections. Do not wait for a routine follow-up when these symptoms occur.

What exactly is in this product, and why is it suitable for my skin? Who manufactured it and how is it stored? Which effects are expected, which are concerning, and how will a complication be treated? What alternative has clearer evidence for my specific concern?
