What should you know about Vichy 89 skin booster?

The word booster describes a cosmetic skincare product, while injectable skin boosters use a needle to place material within the skin. Vichy 89 is applied to the surface and may help skin feel more hydrated and comfortable. It should not be treated as a replacement for medical care for a rash, persistent redness, or a changing lesion. If your concern is texture or visible sun exposure effects, read about [Sun-Damaged Skin](/conditions/photoaging/). [Skin Boosters](/treatments/injectables/skin-booster-treatment/) are a separate treatment category.

Apply the product as directed on clean skin, then use a moisturiser or sunscreen if those are part of your routine. Introduce one new product at a time so irritation can be traced more easily. Keep it away from broken skin and the eyes. Stop using it if burning, swelling, or a persistent rash develops. A patch test on a small area may help people with reactive skin, although it cannot predict every reaction. Check the ingredient list if you have known sensitivities.

Seek medical advice for facial swelling, blistering, intense burning, eye symptoms, or a rash that continues after stopping the product. Ask for assessment if dryness, roughness, or pigmentation does not improve with a simple routine, because eczema, allergy, acne, or sun-related change may need a different approach. If you were offered an injection rather than a serum, confirm the product, technique, and expected aftercare before proceeding.

Ask whether the serum suits your skin condition, which ingredients could irritate you, and how it fits with retinoids, exfoliating acids, or prescription creams. If someone has described it as an injectable, ask whether they mean a [Hyaluronic Acid Filler](/materials/hyaluronic-acid-filler/) or a different treatment, because the risks and aftercare are not the same.
