10 Best Hyaluronic Acid Serums 2025 in the United States

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 Eucerin Radiant Tone Dual Serum Dark Spot Corrector targets those looking to reduce persistent dark spots and achieve more radiant skin. One of its primary strengths is the combination of Thiamidol and Hyaluronic Acid, where Thiamidol is known for its effectiveness in reducing dark spots, and Hyaluronic Acid helps in hydrating the skin and smoothing fine lines and wrinkles. Its concentration of Hyaluronic Acid is a notable benefit, catering to those looking for both hydration and anti-aging benefits.

The formulation is clinically proven and suitable for all skin types, which is a significant advantage for those with sensitive skin or varying skin concerns. The serum’s lightweight and non-sticky nature make it comfortable for daily use, and it won't clog pores, which is ideal for maintaining clear skin. Users have reported visible results in as little as two weeks, making it an attractive option for those seeking quick improvements.

However, the product does come in a relatively small 1 Fl Oz bottle, which may not last long with regular use. Despite this minor drawback, the product's blend of effective ingredients and its suitability for all skin types make it a promising option for those looking to improve skin clarity and reduce dark spots.

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.
