Reviews Summary
Customers say this serum has a silky, light texture that absorbs quickly into the skin. Many reviews mention immediate improvements in skin softness and hydration. While most find it effective for moisture retention, some note issues with pilling under makeup. Reviews are mixed on long-term hydration benefits, with frequent users praising its plumping effects while others report limited results. The serum's consistency receives widespread appreciation, though some find it needs more product than recommended for full coverage. Most users describe it as non-greasy and comfortable for daily use.
