In the realm of the facial hydrator, there is no shortage of choice. The Aesop skin care range features plentiful oils, creams, lotions, gels and serums, all enriched with efficacious ingredients to replenish and support a variety of specific skin types and conditions. But beyond texture, colour and aroma, the differences between products are not always apparent.

Having an abundance of potent hydrators to choose from is a pleasant predicament. Better still: understanding precisely what each product is, how it works, and when to apply it.

Beyond speaking directly with our expert consultants—both in-store and through the live assistance on aesop.com—it is ideal to have this information all in one place, so it can be referenced at will. This article is just such a compendium for facial serums, designed to illuminate what they are, explain how they work, and profile the selection available at Aesop.
