Is the La Roche Posay Hyaluronic AcidπŸ’¦ serum the miracle product to save dry skin?

Two words; hyaluronic acid. Is the La Roche Posay Hyalu B5 Pure Hyaluronic Acid Serum another hydration saver for those dreaded dry patches? Have we found the best hydrating serum for dry skin? Let’s put it to the test!


Dry skin sufferers and skin influencers alike have been raving about this one key ingredient to help boost dry and dehydrated skin into plump and supple glowing skin. It’s one of the beauty industry's best kept secrets and the latest buzz worthy craze for skin care enthusiasts. Hyaluronic acid (HA) is an ingredient commonly found in beauty products that is capable of retaining large amounts of moisture and water. Basically, it’s a holy grail ingredient for my dry skin peeps out there.

One HA product that gained popularity and a mass cult following is The Ordinary Hyaluronic Acid 2% + B5 serum. The product is affordable, it contains few and simple ingredients and it yields the exact results the brand claims. Since its popularity, other brands have followed suit and HA has been appearing in skin care products across the market.

For those of you wanting to up your hydrating skin care game, beauty lovers have discovered the La Roche Posay Hyalu B5 Pure Hyaluronic Acid Serum. This anti-aging and ultra-hydrating facial serum comes in two different sizes and retails anywhere from $33.99 to $53.99. The key ingredients in this serum are a concentrated pure hyaluronic acid, madecassoside and vitamin B5. This serum claims to visibly plump the skin, reduce the appearance of fine lines and wrinkles and will help replenish your skin’s natural moisture barrier. Our Glowish influencer Ji Moon decides to put these claims to the test and see if this miracle serum lives up to its hype.

Ji Moon has very dry and sensitive skin, so she is very selective with what she puts on her face. Many products that claim to be safe for sensitive skin types often end up irritating her skin. Right off the bat, she notices the appearance of the serum. It’s a more cloudy and opaque look compared to the usual clear and transparent appearance in most hyaluronic acid serums. The texture of the serum also seems to be much thicker in consistency and ultimately very sticky. With the first application, the influencer noticed that it absorbed fairly quickly. However, for some reason it still left a very sticky and tacky feeling to the skin.

After the first few days of testing out the product, the serum made her skin feel great and she was able to visibly see a difference in the hydration of her skin.

β€œLiterally my dry patches were gone, it’s amazing.”

-Ji Moon

By the end of the first week, the influencer saw more positive results in terms of her skin complexion. But one aspect of the product she still isn’t a fan of is the strong fragrance.

β€œHonestly, I’m getting used to the feeling of the stickiness. The only thing I’m not getting used to is the fragrance. The fragrance is so strong. It smells like a very nice smelling bathroom. It’s just not the greatest fragrance I would put into skin care.” – Ji Moon

During the second week of her honest review test, things started to take a negative turn when her skin started to become extra sensitive and she began having a rash-like reaction on her cheeks where she had been applying the hyaluronic acid serum. At the very beginning her skin was perfectly fine and even began to show signs of improvement, so to have this unfortunate turn of events was very disappointing.

β€œI realized after looking through the ingredients and kind of researching that the third top ingredient was a type of alcohol … I really don’t like it … I think if you have really sensitive skin, I don’t recommend this product.”

- Ji Moon

The final verdict for Glowish influencer Ji Moon, a 2.5/5 star rating for the product. Though the product didn’t work for her skin specifically, she does reiterate that the product does work for those with dry skin because she did see visible results at the beginning of her experiment. But is it safe to use for sensitive skin types? Probably not, says the influencer, who advises those with sensitive skin to stay away from this product.
