The Philosophy "hope in a jar biome-balance glow serum" is a super lightweight hydrating formula that promises brighter, smoother, more even skin in a week. -- Love the dropper and opaque jar. This product contains Vitamin C, so protecting from light will prolong efficacy. One dropperful of product is enough for my entire face and neck. -- This serum does not have any noticeable scent (even though the ingredient list does indicate fragrance) and is colorless. It is thicker than water, but still runs down my cheek a bit fast. Move quickly and pat it in! There is a slight tacky feel after applying, but it disappears in a few minutes. -- I would definitely say my skin feels hydrated, glowing, and plump after using this. Fine lines, especially around my eyes, seem improved. This product works well underneath sunscreen and makeup to boost hydration. -- After 2 days of morning and night use, I do agree with what the packaging says about "immediate positive impact" of 24-hr hydration, glow, smoothness, and skin barrier protection.
