Frequently Asked Questions


What is hyaluronic acid?

Hyaluronic acid is a moisturizing ingredient that occurs naturally in the skin. It attracts moisture to the skin and defends against dehydration over time. It replenishes the top layers of the skin, causing it to look smoother and plumper.

What is B5?

Vitamin B5 is a water-soluble vitamin that hydrates and nourishes the skin.

How is Hyaluronic Acid 2% + B5 different than other hyaluronic acid serums?

This product contains three types of hyaluronic acid with different molecular weights, allowing it to penetrate mutiple layers of the skin for deep hydration.

Will Hyaluronic Acid 2% + B5 work with my skin type?

This product works with all skin types. It is non-comedogenic and won’t cause irritation.

Does Hyaluronic Acid 2% + B5 treat acne?

This product doesn’t treat acne directly, although it’s a great lightweight hydrator for acne-prone skin. We recommend Salicylic Acid 2% Solution, Niacinamide 10% + Zinc 1%, or Azelaic Acid Suspension 10% for acne.

I’m pregnant or breastfeeding. Is Hyaluronic Acid 2% + B5 safe for me?

This product is considered safe for use while pregnant or breastfeeding, but it’s best to check with your healthcare provider first.

It’s up to you. If your skin is oily, you may not need another moisturizer. Those with dry skin may prefer to apply a heavier moisturizer over it.

Can I mix or layer Hyaluronic Acid 2% + B5 with other products?

Yes. It’s especially useful as a base serum that helps the skin absorb other treatments.
