What is Biodroga Hyaluronic Complex Serum?
Biodroga Medical Institute Skin Booster 3% Hyaluronic Complex Serum is a hydration serum for maximum moisture with a depot effect. Specifically, four different hyaluronic acid molecular weights work together across different layers of the skin. As a result, the formula can protect against moisture loss at the surface. At the same time, it can support the skin’s own hyaluronic acid synthesis deeper down.
This 15 ml bottle is Biodroga’s retail size, sized for a multi-week daily routine.
Key benefits of Biodroga Hyaluronic Complex Serum
- Layered hydration: Biodroga combines four hyaluronic acid forms so they work at different depths of the skin.
- Helps protect against moisture loss: Biodroga formulated the depot effect so that skin keeps feeling hydrated for longer.
- Supports elasticity: Biodroga also designed the complex to help activate the skin’s own hyaluronic acid production.
- Firmer, plumper-looking skin: in Biodroga’s own testing with an outside dermatological test institute, skin looked up to 37% plumper after use.
Key ingredients
Based on the product’s published ingredient list, the Hyaluron Complex combines Sodium Hyaluronate, Hydrolyzed Sodium Hyaluronate and Sodium Acetylated Hyaluronate. Biodroga chose these three molecular weights so that they hydrate at different skin depths. In addition, Acetyl Tetrapeptide-2 is the featured power peptide. Gluconolactone (a PHA) also adds gentle exfoliating support.
How to use Biodroga Hyaluronic Complex Serum
- Before applying, cleanse the skin thoroughly.
- Then apply the serum to the face and pat in gently, avoiding the eye area.
- Afterward, follow with your usual Biodroga moisturizer.
- Use morning and evening for ongoing hydration support.
Who it is for
This serum suits dry and normal skin that wants a noticeable, layered hydration boost. It also suits anyone looking for a lightweight base step before their regular moisturizer.
