Q: How do I apply and do I leave it on to put other face products like eye creams etc.

    Brand expert
  • A: Hello Alondra! Thank you for your question about the application of our Hyalu B5 Face Serum. It's an excellent product designed to replump and hydrate your skin! Here's how we recommend incorporating it into your routine: First, after cleansing and toning your face, dispense 3-4 drops of the Hyalu B5 Face Serum onto your fingertips. Gently apply the serum to your face and neck, pressing it lightly onto the skin and then smoothing it out. The texture is designed to absorb beautifully, leaving your skin feeling fresh and hydrated. Yes, you should definitely leave it on! Serums are concentrated treatments meant to deliver active ingredients deep into the skin. After applying the Hyalu B5 Face Serum, allow it a moment to absorb fully—typically just a minute or two. Once absorbed, you can then proceed with your other facial products, such as your eye cream, followed by your moisturizer. This layering ensures that each product can penetrate and work effectively, with the serum providing its targeted benefits before the heavier creams seal in the hydration and active ingredients.

Q: This productwill help to repair acne scars, and which treatments work best for dark spots versus textured scars?”

submitted by G - 7 months ago
  • A: Hello G! Thank you for asking about our Hyalu B5 Face Serum. It's excellent for hydration and repairing your skin's moisture barrier. This helps with overall skin quality and suppleness. For dark spots (post-inflammatory hyperpigmentation), the serum's hydration supports healthy skin tone. This can contribute to their improved appearance. For textured scars, these involve changes in skin structure. While our serum is beneficial for skin health, significant textured scars often need more targeted treatments beyond a topical serum.

  • A: Hey G, Great question! We recommend to check out the La Roche Posay Mela B3 Dark Spot Serum with Melasyl and 10% Niacinamide to help visibly reduces a range of skin discolorations, including sunspots, age spots, and post-acne marks.​ Don't forget to wear a daily sunscreen to protect your skin.

Q: Is this good for rosacea?

submitted by Meldvs - 1 year ago
  • A: Hello there Meldvs! Thank you for your interest in our Hyalu B5 Face Serum. This product's hydrating formula may be suitable for some with rosacea, but we strongly recommend consulting a dermatologist before use. While hyaluronic acid and vitamin B5 are generally well-tolerated, individual reactions vary. Always perform a patch test before applying to your entire face to check for any irritation. A dermatologist can best assess your specific rosacea and recommend an appropriate skincare routine.

    submitted byLa Roche-Posay Product Expert - 1 year ago
    Brand expert
  • A: Great question. Our products are dermatologist tested, allergy tested, sensitive skin tested and suitable for all skin types, including sensitive skin. If you have concerns about incorporating new products into your skincare routine or if you have a pre-existing skin condition, we would always first and foremost recommend consulting with a doctor or dermatologist to ensure that you receive advice tailored to your individual needs and we would also suggest carrying out a patch test 24 hours prior to first use

Q: is it 100% pure hyaluronic acid

submitted by Unhappy - 24 days ago
  • A: Hello Unhappy. Thank you for your interest in La Roche Posay Hyaluronic Acid Serum, Hyalu B5 Face Serum - 1.01 fl oz. No, the La Roche-Posay Hyalu B5 Face Serum is not "100% pure Hyaluronic Acid." In the world of skincare, a serum is almost never 100% pure hyaluronic acid because the pure powder form of hyaluronic acid is incredibly potent; even a 1-2% concentration is considered very high and effective for the skin.If you were to apply 100% pure hyaluronic acid powder to your face, it would actually draw moisture out of your skin rather than into it. Hyaluronic acid works best when formulated in a water-based serum (usually at a concentration of 0.5% to 2%) so it can carry that moisture into your skin cells. We hope this information has been helpful and that you will try our products soon!

    It doesn’t work any better than “The Ordinary” hyaluronic acid that costs a fraction of the price. And the scent is too strong, I don’t even want to use it.

    Great!

    I have been using the Hyalu B5 Serum for a couple of years now. Many reviews say it is sticky, but I find if I slightly moisten my fingertips and then apply, it goes on smoothly and absorbs into skin rapidly. I have no need for an additional moisturizer. Scent is strong as many complain, but only for a minute. I am allergie and sensitive to many chemicals found in skincare products so this one is my holy grail. Love this stuff!!

    Hello Clionah! It is wonderful to hear that the serum delivered the results you were looking for, though we sincerely regret that the fragrance prevented it from being a perfect match for your routine. We carefully craft our scents to ensure they meet our strict safety standards for sensitive skin, but we completely understand that sensory preference is a very personal part of any skincare experience. To help manage the presence of a scent, you might find that applying the serum to slightly damp skin and immediately following with a fragrance-free moisturizer helps to lock in the formula and allows the aroma to dissipate more quickly. Your feedback is incredibly important to us as we continue to develop products that prioritize both high efficacy and the diverse needs of our community.

    Hydrating but very scented

    Hydrates skin but wish there was a non fragranced version. Despite being allergy tested, I don’t think this is a great fit for very sensitive types unfortunately. Would rebuy only if they ever came out with a fragrance free version.
    1 reply from Consumer Care Center team - 15 days ago
    Hello Kitkat7! We truly appreciate you sharing your experience with the Hyalu B5 Serum and are glad to hear it provided the hydration your skin needed. We understand that even with rigorous allergy testing, fragrance can be a personal preference or a concern for those with particularly reactive skin. Your feedback regarding a fragrance-free version is incredibly valuable as we are constantly looking for ways to better serve our community of sensitive skin users. For those experiencing heightened sensitivity, it can be very helpful to perform a small patch test on the inner forearm for 24 hours before full facial application to monitor how your skin responds to the formula. Additionally, ensuring your skin is slightly damp before application can help the hyaluronic acid lock in moisture more effectively while minimizing the potential for irritation. Thank you for choosing us for your skincare journey and for providing this honest insight.

    Hello bsky! We appreciate your honesty and are sorry to hear that the texture of the Hyalu B5 Serum was not to your liking, especially as a fan of our other products. The "sticky" sensation you described is actually a common characteristic of high-concentration hyaluronic acid as it begins to bond with moisture and "plump" the skin's surface. To minimize this tackiness, we suggest applying the serum to slightly damp skin and using only two to three drops for your entire face. Gently pressing the product into the skin with your palms and allowing it to absorb for about sixty seconds before applying your moisturizer will help the formula set more comfortably. We value your feedback as a loyal consumer, as it helps us understand the diverse texture preferences within our community.

    Issues with Absorption and Layering

    I found that this product did not really absorb into my skin. I attempted to use it during both my morning and evening routines, but I encountered significant issues during the day. Because the serum is very thick and sticky, I am unable to apply any additional products over it, such as sunscreen or moisturizer. I tried using different tools and various product combinations to see if it would make a difference, but nothing could be layered on top of this serum without issues. Due to the texture, I have been forced to use it only at night.
    1 reply from Consumer Care Center team - 18 days ago
    Hi SKIM! We are sorry to hear that the texture of the Hyalu B5 Pure Hyaluronic Acid Serum has made it difficult to integrate into your daytime routine. This serum is formulated with a high concentration of two types of pure hyaluronic acid, which creates its signature "plumping" and moisture-binding effect, resulting in a richer, slightly more viscous consistency than traditional watery serums. To help the serum absorb more effectively and reduce any sticky sensation during the day, we suggest applying just two to three drops to thoroughly cleansed, slightly damp skin. Using a gentle pressing motion with your palms—rather than rubbing—allows the formula to integrate more seamlessly with your skin's surface. Waiting a full sixty seconds after application before moving on to your moisturizer or sunscreen can also help the product "set," which typically prevents any pilling or layering issues. We appreciate your persistence in trying different combinations, and we are glad it is at least providing nighttime benefits for you!
