Good afternoon Rachel, Thank you so much for taking the time to leave you review.
Our Hyaluronic Serum increases the skin's internal water content, which helps to keep skin firm and plump at a cellular level, whilst balancing and strengthening barrier function. As it's Water Based, it does need to be followed by a Moisturiser in order to nourish the skin. Without one you could be left feeling dry as it absorbs into the skin without leaving a barrier.
If you ever have any questions, please feel free to reach out to us at any time. We are always here to help :-)
