Visibly plumper and hydrated skin thanks to the synergy of four pure, organic molecular weights. The hyaluronic acid serum is an intensive facial treatment formulated to retain skin moisture and counteract signs of ageing. This pure active ingredient by La Saponaria combines four molecular weights to hydrate both deep and superficial layers, ensuring an immediate plumping effect and more elastic skin for 24 hours. ORGANIC HYALURONIC ACID SERUM The effectiveness of four different molecular weights Unlike many traditional serums, this organic formula acts at different skin levels. Low and very low molecular weights penetrate deeply for a structural anti-ageing action, while high weights form a protective film on the surface for a visible plumping effect.

This active ingredient by La Saponaria is formulated with 4 different molecular weights precisely to overcome this limitation. Low and very low molecular weights penetrate the deeper layers of the epidermis for a long-term plumping action, while medium and high weights work on the surface to maintain immediate hydration and smooth expression lines. Must it necessarily be applied to damp skin or is that just an urban legend? Applying hyaluronic acid serum to slightly damp skin is recommended because the molecules attract and retain moisture. However, thanks to its formula enriched with rose and melissa constitutional waters, this serum ensures excellent hydration even on dry skin without causing an unpleasant tight feeling. How many drops are really needed to avoid wasting product while getting results? The formula is extremely concentrated: 3 or 4 drops are enough to cover the entire face and neck. If used as a booster in your moisturiser, just 1 or 2 drops are sufficient. This approach avoids waste and prevents pilling caused by excess unabsorbed product. What is the difference between ordinary recycled plastic and the bottle's re-bottle plastic? Re-bottle plastic is post-consumer recycled plastic derived from household plastic waste that has actually been used and recycled. Compared with industrial recycled plastic, re-bottle has a much lower environmental impact because it closes the loop on municipal waste recycling, helping to reduce the production of virgin plastic. Can it cause breakouts or spots on combination or oily skin even though it is natural? No, this hyaluronic acid serum is completely oil-free and non-comedogenic. Its light, watery texture absorbs immediately without clogging pores, making it perfect for combination or oily skin that needs deep hydration without the heaviness of oils or butters. It is also dermatologically tested for the most sensitive skin.
