Reviews Summary
Customers say this serum has a lightweight, easily absorbed texture that doesn't feel sticky. Many reviews mention reduced oiliness, especially in the T-zone area. The formula helps with uneven skin texture and appearance. While most users report positive experiences, some note it may not suit sensitive skin. Reviews frequently highlight the product's gentle nature and smooth application. Many are repeat purchasers, though some wish for a larger bottle size.
