Hyaluronic Acid 2% + B5 (New Formulation)
The 2024 reformulation significantly improved this cult classic by adding 5 forms of HA and ceramides while removing the sticky texture. It remains the best entry-level serum for pure hydration efficiency.
Quality & Materials
Uses low-, medium-, and high-molecular weight HA, plus a cross-polymer and pro-vitamin B5. Now includes ceramides to lock in the moisture that HA attracts.
Evidence & Testing
While the specific formula lacks large-scale RCTs, the individual components (HA and Ceramides) are among the most studied in dermatology.
Brand Transparency
DECIEM provides full ingredient percentages and pH levels (6.50 - 7.50) for every batch.
Value Assessment
Unmatched value. It provides the core necessity of an HA serum for less than $10, making high-quality skincare accessible.
Why Not Alternatives?
It beats the Inkey List's HA by offering a more complex multi-molecular weight profile and added ceramides for the same price point. It avoids the unnecessary essential oils found in many 'clean beauty' HA serums at Sephora.
