I’ve used many hyaluronic acid serums over the years and never noticed a meaningful difference. When a bottle ran out, I could go months without replacing it and my skin looked and felt exactly the same. I eventually assumed HA serums simply weren’t capable of doing much for my skin. This one proved me wrong.

I use several active ingredients, including tretinoin, so I knew my skin was prone to dryness. What I hadn’t realized was that it had gradually developed chronic low-grade dryness, sensitivity, redness, and inflammation. After about a month of using Bay Harbor Beauty’s Ceramide & Hyaluronic Acid Serum, my skin barrier finally felt restored. My skin became properly hydrated—full, supple, soft, calm, and glowing. Fine lines appeared softer, and my skin regained the smoothness and structure that give it a healthier, more youthful appearance.

The texture is thicker than I typically associate with a serum, so it took me a few applications to realize that it doesn’t need to be applied like an moisturizer. A thin layer is all you need. Give it a moment to absorb, and it layers beautifully under moisturizer, sunscreen, and makeup without feeling heavy.

This is the only HA serum that has ever made a visible and lasting difference in my skin, including compared with expensive medical-grade and med-spa brands. The ingredients are purposeful and thoughtfully chosen, and the value per dollar is excellent—especially when you apply the small amount actually needed. I’ve already repurchased it, and it’s now an essential part of my routine to keep my skin barrier healthy.

I previously spent $185 on a similar vitamin C serum. Although I never saw a noticeable improvement in my skin, I continued buying it because I believed the antioxidant protection justified the price. Bay Harbor Beauty’s Vitamin C E Ferulic Serum delivers the same proven antioxidant combination at the same concentrations—but with a far more thoughtful and skin-friendly formula.

What surprised me most was realizing that my former serum had been causing persistent low-grade irritation, redness, and dryness. I didn’t fully recognize it until I switched to this one. The added calming ingredients make an enormous difference: I can use it every day, even on sensitive areas, without irritation. It absorbs beautifully, layers well, and leaves my skin looking healthy and radiant.

This is quality science paired with quality ingredients—a proven formula made even better through thoughtful formulation. It’s concentrated rather than padded with pointless ingredients, so a little goes a long way. It’s also ethically priced by a company that clearly values its customers instead of taking advantage of them.

I’ve already repurchased it and will continue to do so. It has become a permanent staple in my routine, and I will never go back to the overpriced serum.

After just 4–6 weeks, this copper serum genuinely changed my skin for the better. My complexion looks noticeably healthier, more even, radiant, and supple. My skin feels smoother, better nourished, and more resilient, with a natural glow that I wasn’t getting from other products (and I’ve tried all the costly med spa products).

The formula is elegant, absorbs beautifully, and layers well with the rest of my routine. It’s made with quality, purposeful ingredients and isn’t diluted with unnecessary fillers, so a little truly goes a long way. I also appreciate that it’s ethically priced—especially for a serum of this quality and effectiveness.

So few skincare products deliver visible results beyond temporary hydration or cosmetic effects. This one has made a meaningful difference in the overall health and appearance of my skin. It has earned a permanent place in my routine, and I’ve already repurchased.

Love every product I’ve ever ordered and I have ordered multiple times! Sake cleanser and moisturizer, body butter in citrus mimosa and soleil blanc are divine. The hydrating essence and ceramide/hyalaronic acid serum are helping my sensitive face tremendously! Will continue to purchase!

I’m loving this advanced silk renewal body lotion. Even my husband commented on how good my skin feels. Full transparency: I bought this to see if it would help my numerous SKs, and it did not. But Julie educated me that SKs often need more intensive treatment. That aside, it absolutely works for exfoliating and renewing your skin. I’ll be keeping this in my daily routine!

I have added the Copper Serum to my BHB skin care regimen 1 month ago. I haven't noticed too much of a difference in my skin since adding it. I'm sure it will take longer to notice a difference. I have been using BHB products since the end of March and I have noticed a big difference in my 57 yr old Scottish / Irish menopausal skin! My fine lines & crows feet are almost unnoticeable. BHB skin care line has changed my skin and made it look and feel so much better!

The oil perfume from Bay Harbor is definitely a favorite of mine! I always wear it on my wrists each morning, and I can still catch a whiff of it all day long. Plus, it lasts way longer than any other oil perfume I’ve tried before.

I’m obsessed with all of these products! I’m already ordering a second time. There are other things I must try. Thank you, Julie!

Love this serum, the integrity of the texture of the skin on my face is improving. This and copper are a great combination.
