10 Best Hyaluronic Acid Serums 2025 in the United States

The Ordinary Hyaluronic Acid 2% + B5 serum combines a high concentration of 5 types of Hyaluronic Acid with ceramides and Pro-Vitamin B5 to provide multi-depth hydration. Its strengths lie in its formulation, which aims to hydrate various skin layers, making the skin appear plumper and smoother. The addition of ceramides is beneficial for locking in moisture and supporting the skin’s barrier, which enhances skin health and reduces fine lines and wrinkles.

Pro-Vitamin B5 further boosts moisture retention and supports the formation of essential barrier components, making this serum suitable for all skin types. The product is fragrance-free, which is a plus for those with sensitive skin or allergies to scents. The packaging, featuring a 1 fl oz bottle in a pack of two, offers convenience and good value. However, some users might find it less appealing if they prefer single larger bottles.

The Ordinary has a solid reputation for affordable yet effective skincare, but the serum's efficacy can vary based on individual skin types and issues. It is ideal for those looking for an affordable, multi-functional hydrating serum that addresses various skin concerns, although individual results may vary.

The La Roche-Posay Hyalu B5 Pure Hyaluronic Acid Serum is a strong contender in the hyaluronic acid serum market, especially for those looking to tackle fine lines, wrinkles, and dehydrated skin. This serum features a concentrated blend of pure hyaluronic acid, which is known for its hydrating and plumping properties. The inclusion of Vitamin B5 and madecassoside adds to its skin-repairing benefits, making it particularly effective for dry and sensitive skin types.

Users have reported noticeable improvements in skin hydration, softness, and suppleness within just four weeks of use, which is impressive. The product is also oil-free, noncomedogenic, and allergy-tested, ensuring it is safe for all skin types, including sensitive ones. However, the serum does have a scent, which may not be suitable for everyone, particularly those with fragrance sensitivities.

The packaging is practical and the serum is easy to apply, but the small bottle size (1.45 ounces) might mean you’ll need to repurchase it relatively frequently if used daily. La Roche-Posay is a reputable brand with positive reviews, giving consumers confidence in the product’s effectiveness. This serum is ideal for those looking to add a potent anti-aging and hydrating step to their skincare routine.

The Ordinary Natural Moisturizing Factors + Hyaluronic Acid is a lightweight, non-greasy hydrator designed to support and strengthen the skin’s natural moisture barrier. It combines hyaluronic acid with skin-identical ingredients such as amino acids, ceramides, urea, and fatty acids, offering both immediate hydration and longer-term skin barrier benefits. The formula is unscented, which is great for sensitive skin and those who prefer no added fragrance. It suits all skin types and can be applied as the last step in a skincare routine.

The Ordinary brand is well-known for affordable, effective skincare and has a strong reputation supported by many positive reviews. Packaging is simple and functional but not luxurious, reflecting the brand’s focus on value. While it hydrates well, it is more of a moisturizer than a pure serum, so those looking for a concentrated hyaluronic acid serum might want to consider that.

This product is a great choice if you want an easy-to-use, lightweight moisturizer with multiple hydrating ingredients from a trusted brand, especially if you’re new to hyaluronic acid or want to support your skin barrier without heaviness.
