Which Hyaluronic Acid Serums Actually Fight Signs of Aging? I’ve Tested Dozens - Here Are 5 Serums That Actually Work

This is the only serum on this list that consistently leaves skin looking smoother, brighter, more even, and visibly reduces fine lines by morning without irritation. I’ve been using Renew for over a year now and it continues to deliver fantastic results, which keeps it at the top of my list of the best serums and why I would heartily recommend it to any patient of mine looking for hydrated, raidant, & visibly age-defying skin.

And I’m not the only Dermatologist who thinks so. From Dermatologists I have connected with personally to others I connect with online I consistently see Renew at the top of Dermatologist  recommendations and for good reason! This serum delivers visible improvements fast with many users seeing results in a matter of days or weeks.

What sets Renew apart is that it does not rely on hyaluronic acid alone. It contains triple-weight hyaluronic acid, which is fantastic because it helps support hydration on multiple levels of the skin and reduces visible signs of aging, but it also combines both well-researched and powerful botanicals such as Ferulic Acid, Alpha Hydroxy Acid, Fruit Derived Vitamin C, Kakadu Plum, and Bilberry. I love that Renew is a multi-functional serum that visibly addresses some of my patients biggest skin concerns.

✅ Dark Spots & Brightening
✅ Fine Lines & Wrinkles
✅ Uneven Texture & Tone
✅ Exfoliation & Dull Skin
✅ Hydration

You wake up with skin that feels plump & hydrated, looks even & glowy, and is not irritated. It’s also lightweight, but effective, and absorbs without leaving a sticky residue. It’s great for those with mature skin, anyone who wants to get ahead of signs of aging, and those with active lifestyles.

Looking for a serum that’s thoughtful about both your skin and the planet? This serum is a perfect fit! Renew Resurfacing Night Serum is created with naturally-derived, botanical ingredients and is certified cruelty-free and vegan too! And an added bonus: their bottles are made with recyclable glass.

Marketing can be tricky, but clinicals don’t lie. Renew has been clinically proven to reduce the look of fine lines and wrinkles, hydrate skin, and visibly improve skin tone & texture.

So if you’re looking for a mult-benefit Hyaluronic Acid Serum that actually works and visibly reduces fine lines & wrinkles for more youthful looking skin then I would recommend trying Renew.

Coming in second place is Estée Lauder’s Advanced Night Repair Serum, which has packaging that reminds me of having an old-money, old Hollywood vibe.

This well-known serum has a silky texture that spreads very easily, and is very lightweight. I find it a bit more watery than other serums on the list.

The Advanced Repair Night Serum I think is particularly great for mature skin and would appeal to older women, similar to Renew, and is a group that makes up a large portion of my client base.

This serum contains hyaluronic acid, glycerin, tripeptide-32 as well as tocopheryl acetate. Great ingredients to support a radiant complexion. However, for those looking to avoid synthetic dyes I should note it contains Red 4 (Ci 14700) and Yellow 5 (Ci 19140).

The synthetic dyes combined with the higher price tag are two factors that put it as second and not at the top of the list.

Taking third place is La Roche-Posay’s Hyalu B5 Serum. You may be familiar with this serum as it is sold in many drugstores. This serum has a very clean, fresh fragrance that I personally enjoy when applying.

The serum itself is thick and has a bouncy gel texture that feels cushiony and hydrating, which can make it a great choice for those with very dry skin that enjoy a thicker serum.

Hyalu B5 Serum combines hyaluronic acid with B5 and madecassoside and is formulated to help replenish the natural moisture barrier. It can be a good entryway serum for a new patient, which combined with the supporting ingredients is in good part why it made it onto my list. For skincare pros and those looking for a more multi-functional serum they may want to try a more robust serum.

A solid starter serum although results are more subtle compared to multi-benefit formulas. 

Fourth on my list is Peter Thomas Roth’s Water Drench Hyaluronic Liquid Gel Cloud Serum. I came across this serum because a lot of my patients use it, and I wanted to try it myself.

The Gel Cloud Serum is the only serum on the list that includes Sodium PCA. Studies show this particular ingredient can visibly moisturize & hydrate your skin’s appearance.

When I tried this serum, I felt like it gave me a luminous glow. My skin felt very moisturized and I looked less dehydrated after using it.

I felt like this serum was more like a cream because of its thicker consistency. However, some of my patients do prefer this cream-like texture – especially my male patients.

Why’s this one lower on my list?

I personally found the mild odor to be a deterrent for me - it made me not want to use it - which is something you never want in skincare.

One of my biggest gripes with this serum is its lack of powerhouse ingredients. It’s missing out on some of the hero ingredients that other serums on this list have, such as Ferulic Acid, Vitamin C, Peptides, AHAs, and more.

It’s also worth noting this serum includes Hydrolyzed Silk and Honey Extract, meaning it isn’t suitable for vegans.

While I feel Peter Thomas Roth’s serum is a strong contender in the world of HA serums, the lack of my preferred ingredients loses me. Still, I believe it’s a good option for those looking for a thicker, creamier HA serum.
