Both scented and unscented (no fragrance added) options appear. Textures are commonly described as lightweight, non-greasy, fast-absorbing, and some are characterized as milky or pearlescent.
Pack sizes in this set range from about 0.5 fl oz up to 4 fl oz, with several common sizes around 1 fl oz and 1.69 fl oz.
Instructions generally recommend applying the serum to cleansed face and neck once or twice daily. Products note using a few drops or a pump dispense and advise applying the serum before moisturizer and makeup.
Advertised anti-aging effects include reduction of wrinkles and fine lines, firmer or plumper-looking skin, smoother texture, improved tone or brightness, and increased hydration.
Formats include single serums and multi-formula products. One listing describes a two-in-one pump that dispenses both a translucent and a milky formula to address multiple signs of aging in a single application.
