Hydrating Serum or Face Oil: Which Should You Buy?

If you want a lightweight, milky layer before cream, consider our BLEMISH THIRST RESCUE SERUM. If you want an oil finish after moisturizer, consider our SUPER GLOW DEW. If avoiding fragrance or essential oils is a priority, check those ingredient requirements before choosing by texture.

BLEMISH THIRST RESCUE SERUM

What would you like to add to your current cream?

When you want to keep your cream and add just one product, a hydrating serum and a face oil can seem like competing options. Start with the texture you want and where you want it in your routine, rather than assuming one will be more powerful.

Here, we're comparing two PURE'AM products by texture, official application order, and ingredients you may wish to avoid. This is not a ranking of how well all hydrating serums and face oils moisturize. If you're already happy with your cream's moisture and finish, there's no need to rush into another purchase.

Want a lightweight, milky layer before cream?

We describe BLEMISH THIRST RESCUE SERUM as a lightweight milky fluid that breaks into a water-light texture as you spread it. It's an option to explore if that is the kind of layer you'd like before your cream. See our serum texture description.

The featured ingredient combination includes ectoin, niacinamide, and plant-derived squalane. The full ingredient list also includes jojoba seed oil. A hydrating serum is not necessarily oil-free: this one is a lightweight serum that also contains lipid ingredients. Check our serum's featured ingredients and full ingredient list.

Our official directions are to apply it evenly to the face and neck after cleansing and toning, then follow with AUTHENTIC BARRIER CREAM BALM. That makes it the option to consider when you want a serum step before cream. See the serum application directions.

Want an oil finish after cream?

SUPER GLOW DEW contains squalane and plant oils. Its full ingredient list includes sweet almond, chia seed, sunflower seed, and jojoba seed oils, and we describe its texture as lightweight and silky. These are useful distinctions when deciding whether you want an oil finish. See our face oil texture and ingredient information.

Our official directions are to apply it evenly to the face and neck after moisturizer. In the morning, follow with sunscreen. Even if the product page calls it a serum, follow its product-specific directions rather than moving it before cream based on the name. See the SUPER GLOW DEW application directions.

Consider this option when you want to keep your cream and add an oil finish afterward. Being an oil is not, by itself, a reason to conclude that it moisturizes better than the hydrating serum.

Does avoiding fragrance or essential oils change the choice?

If avoiding particular fragrance ingredients or essential oils is a purchase requirement, apply that filter before choosing your preferred texture.

  • BLEMISH THIRST RESCUE SERUM: We label it fragrance-free and essential-oil-free on the official serum page.
  • SUPER GLOW DEW: Its full ingredient list includes Rosa Damascena Flower Oil and Citrus Aurantium Bergamia (Bergamot) Fruit Oil. Check the face oil ingredient list.

If you avoid rose or bergamot oils, SUPER GLOW DEW does not meet that ingredient requirement. You could look first at our serum, which is labeled fragrance-free and essential-oil-free.

Those labels are not a guarantee that a product will be irritation-free for everyone, nor do they establish a safety ranking between the products. Use them as a starting point, then check the full list for individual ingredients you avoid.
