A beauty editor"s honest La Roche-Posay Hyalu B5 serum review

Use—How bởi you use La Roche-Posay Hyalu B5 serum?

Pollution has been shown to tear tiny holes in our delicate skin barrier, causing water to leak out & irritants to lớn creep in. To protect against this type of damage, fill the dropper and apply three to lớn four drops of La Roche-Posay Hyalu B5 Pure Hyaluronic Acid serum onto clean skin.

By day follow with your best vitamin C serum for an added layer of free-radical protection and SPF—you could even use the matching La Roche-Posay Pure vi-ta-min C10 serum for the best results. At night, apply pre moisturizer, which should contain ceramides to lock in all the hydrating goodness from the serum.

Experience—How does the La Roche-Posay Hyalu B5 serum feel?

Like most hyaluronic acid serums, it has a gel-like texture, which at first cảm ứng feels quite sticky before quickly absorbing into the skin. If you have sensitive skin, don’t be put off by the blue bottle—the actual serum is clear so there’s no danger of artificial colors riling your skin.

I also like to keep the La Roche-Posay Hyalu B5 Pure Hyaluronic Acid serum in mini fridge for skincare in the summer months or after a night out as the texture feels delicious when taking down puffiness.

Results—What does La Roche-Posay Hyalu B5 serum do?

In a nutshell, this La Roche-Posay hyaluronic acid has both immediate & long-term effects for dehydrated, mature skin that’s losing volume. Upon application it’s lượt thích a tall drink of water that floods skin with moisture, plumping và ‘filling out’ dehydration lines & wrinkles.

With continued use, madeccassoside và vitamin B5 encourage collagen production and aid in the skin’s natural regeneration process for improved firmness, elasticity và less pronounced wrinkles.

It does so by combining two sizes of hyaluronic acid in one formula—the large sodium hyaluronate molecules plump the surface of the skin while small hydrolyzed (broken up) hyaluronic acid molecules bind water to collagen in the deeper layers of skin. The La Roche-Posay Hyalu B5 Pure Hyaluronic Acid serum also includes its proprietary soothing thermal water.

Value—Is the La Roche-Posay Hyalu B5 serum worth it?

For $36.99, this serum isn’t prohibitively expensive, but it is the most pricey hyaluronic acid serum that I’ve tested.

That said, it has a robust formula, the science stacks up & it tackles dehydration, wrinkles and volume loss, which makes La Roche-Posay hyaluronic acid a solid skin care purchase in my books.

How it holds up

Another French skin care brand that also includes thermal water in its hyaluronic acid serum is the Vichy Mineral 89 serum. For me, this serum is better suited to sensitive skin as it only contains 11 ingredients and is unscented. Despite the rigorous dermatological testing behind the La Roche-Posay Hyalu B5, its mild hint of fragrance could still irritate sensitive although the more well-rounded formula, which includes more anti-aging ingredients than the Vichy Mineral 89 serum, is appealing to those who are looking lớn target hydration as well as loss of firmness.

The biggest difference between the La Roche-Posay Hyalu B5 và The Ordinary Hyaluronic Acid 2% + B5 (apart from the price) is the concentration of hyaluronic acid. The Ordinary boasts a massive 2% whereas La Roche-Posay only contains 0.3%. Given cell renewal slows down with age, the fact that Medik8 Hydr8 B5 Intense also contains gently exfoliating lactic acid gives it an edge when it comes lớn a hyaluronic acid serum designed for mature skin. This one will cost you around $55, though.

My Imperfect Life’s verdict on the La Roche-Posay Hyalu B5 serum

I’m not going to lớn lie, I’m a big fan hâm mộ of The Ordinary Hyaluronic Acid 2% + B5, which is often my benchmark for other skin care formulations. But for me La Roche Posay is the personification of everything that’s amazing about French pharmacy skincare: it’s developed and tested by dermatologists, deploys active ingredients and is kind to your wallet. Basically, it feels very accessible.

I regularly use several products in the line as they slot effortlessly into my routine without causing flare ups and is excellent value for money. When I travelled a lot in my previous job you’d inevitably find a bottle of La Roche-Posay Hyalu B5 serum in my hand luggage (at 30ml it’s ideal) to ward off a Sharpie forehead from all that dry in-flight air. I loved how it immediately imparted a healthy glow despite the jet lag and made lines look more soft focus. But you don’t have to lớn take my word for it.

Trials by the brand are pretty impressive, too—there’s a 24% improvement in elasticity và firmness after four hours & skin is 70% more hydrated. After one month of use, 87% of subjects had a more elastic và even skin tone.
