Customers say this primer controls oil effectively and keeps makeup matte throughout the day. Many report it works best for very oily skin, with some noting it requires a small amount and works particularly well on the T-zone. Common feedback mentions the smooth application and long-lasting results, though some users experience patchiness or flaking if not applied correctly. A few report it feels cakey or doesn't perform well in extreme heat or humidity. Most praise its ability to prevent shine and keep makeup in place for extended periods.
