KEY INGREDIENTS

Hyaluronic Acid (HA): A polysaccharide (carbohydrate polymer) found naturally within the skin. When used in a formula, HA is an effective humectant that can hold a large amount of water to help maintain the skin's moisture.
Madecassoside: Derived from the Centella Asiatica plant, madecassoside is known for its nourishing properties.
Glycerin: Derived from vegetable sources, it's an excellent humectant. It helps hydrate skin by absorbing water from the surrounding environment.
Vitamin B5: Panthenol (provitamin B5) is a key ingredient used in some La Roche-Posay formulas to help the skin feel soothed and moisturized.
Dimethicone: A silicone-based polymer used as a skin protectant to help reduce water loss.
La Roche-Posay Prebiotic Thermal Water: A soothing water sourced in the town of La Roche-Posay in France and a core ingredient in most of our products. It contains a unique combination of minerals, trace elements, and a high concentration of selenium, a natural antioxidant.

Rated 5 out of 5 by from Love Love Love the B5 Serum I have extremely dry skin with rosacea and this product has been a lifesaver. I use it morning and night and sometimes add the triple moisturizer on top of it for extra protection in the winter and before bed. Love this stuff.

Rated 3 out of 5 by from Just ok This was just ok. I don’t think it’s worth the price. This product was heavily scented. The texture of the product was good. I felt like it didn’t absorb that well. There are more affordable options out there.

Rated 5 out of 5 by from Results from first time This is one of the best hyaluronic acid I’ve ever put on my skin. You see results immediately! The smell is great, better than others on the market and it absorbs so quickly! My skin literally drinks it.

Rated 5 out of 5 by from Best Serum I have tried This serum does wonders for all over face moisturizing without any allergies. I have sensitive skin and always get irritation when applying serums all over face, but not this one. It has done so well for my crows feet and tightened up my under eye skin noticeably. I use it morning and once at night and my face drinks it up. Best serum and I have many expensive ones in my collection.

Rated 5 out of 5 by from This serum is great This serum is great I wash my face with the face wash, then put a tiny amount of this all over my face before the day time lotion. I think it really helps.
