Ana tried out the Stay In Line Lip Liner in Luminous color by Jason Wu Beauty. She was searching for a nude lipstick that would complement her tan skin. However, she found the color to be a little more brown than she expected. Despite this, she was impressed with the lip liner's performance, especially since she wasn't wearing any foundation. Ana believes that it will look even better once she applies foundation. Overall, the Stay In Line Lip Liner in Luminous color seems to be a good product, providing a smooth and precise application. However, the shade may not be suitable for those looking for a lighter nude color.
