Prime Ingredients

Hyaluronic Acid

Even if you are a skincare enthusiast, you would know how much of a magical ingredient hyaluronic acid is in hydrating your skin. When you know your moisturizer, serum, lotion, or any cream is supposed to hydrate and moisturize your skin, you know it is probably this ingredient. This humectant power can hold vast amounts of water so your skin doesn’t feel thirsty and turn dry. It quenches down the thirst of your skin. 

Vitamin B5

Vitamin B5, or Pantheonol, helps moisturize and protect skin. It also possesses healing and soothing properties, so skincare products containing this usually help your skin feel calm and relaxed. It helps enhance the skin’s natural barrier and hence helps with hydration. 

La Roche-Posay Thermal Water 

Sourced from France, this ingredient is one of the most essential ingredients in most skincare products the brand offers, hence the name. It is often used for its soothing and anti-irritating properties, which help calm redness or irritated skin. Moreover, Thermal Water contains a blend of minerals and Selenium in high concentrations, as it has antioxidant properties that help protect the skin from oxidative stress or environmental stressors. Because of these benefits, Thermal Water becomes suitable for those with sensitive skin.

Customer Feedback | Hyalu B5 Serum Before And After Reviews

A user named Julianna commented, ‘It works very well for sensitive skin. I have dry and sensitive skin, and I like how it works. I could literally say that it made my skin more soft and hydrated. I had problems with my moisture barrier, and it helped with that as well. The one thing I would want to change in it is it’s fragrance. It isn’t overpowering or unpleasant; considering how the serum works, I can overlook it. However, being free from fragrances or having a very light and mild fragrance would make people more happy with this serum.’

Hyalu B5 Serum Before And After Reviews

Another user, DignDevour, disappointedly said, ‘The formula of this serum is very thick and sticky. It does not get absorbed into my skin and just sits there, making me doubt if all the ingredients are getting into it. The scent is light and pleasant, so that is not much of a concern. Since I opened it already, I will be using it, but I will not rebuy it. Though I have purchased other skincare products from this brand and was impressed by the ingredients, I still don’t think this particular serum was for me!’

Ashley happily commented, ‘This was like a miracle for my combination skin. My dermatologist recommended it because I had combo skin and dry cheeks. Honestly, this serum was a game-changer for me. It has done an excellent job of keeping my skin hydrated and not dry. I usually search for lotions and serums, but now I have found ‘the one.’ I will continue to repurchase this. Though it is a little expensive, it is worth it because a little goes a long way!’

Another user, P. Brock, said, ‘The serum makes your skin hydrated, but it also makes it look and feel oily and greasy. It also gives you a tacky feel. To tell you, I have normal skin. I used this serum and applied moisturizer later, but it still gave the same oily feel.’

Hyalu B5 Serum Before And After

A user named JHack commented, ‘The scent is so strong, I have difficulty handling it every night. I know that these types of skincare products, like serums, are not supposed to have fragrances or perfumes, but this serum has a very strong and unpleasant one. I want to know why the brand has done this, especially with sensitive skin products.’
