Sodium hyaluronate is the salt form of hyaluronic acid and has a smaller molecular weight, which allows it to absorb more readily into the skin's surface. It works by attracting and binding water molecules, which helps keep skin hydrated throughout the day. Over consistent use, this can visibly soften fine lines and improve the overall texture of the skin.

Yes. Despite what many people assume, oily and acne-prone skin can be dehydrated, and using a hydrating concentrate like this one can actually help balance oil production over time. The formula is lightweight and absorbs quickly without leaving a greasy residue. Squalane, one of the key ingredients, is non-comedogenic and well-tolerated by most skin types.

Absolutely. Applying this concentrate before your moisturizer is actually an ideal layering strategy. The sodium hyaluronate draws water into the skin, and your moisturizer then acts as a seal to help prevent that hydration from evaporating. This combination directly addresses trans epidermal water loss, which is one of the primary causes of chronic skin dryness.

The formula does contain lavandin oil and camphor bark oil, both of which contribute a subtle natural scent. These are essential oils rather than synthetic fragrance additives. If your skin is highly reactive to any essential oils, we recommend checking with one of our estheticians before use.

Squalane is a lipid that closely mimics the skin's own natural oils, making it an effective barrier-supporting ingredient. In this concentrate, it works alongside sodium hyaluronate to reinforce the skin's surface so that moisture is less likely to escape. It absorbs without feeling occlusive, which makes it suitable for all skin types including those that tend to feel congested.

Rosehip fruit oil is a source of essential fatty acids, including linoleic acid, that help support a healthy skin barrier. A compromised barrier is one of the main reasons skin loses water so quickly, so including rosehip in a hydration concentrate makes practical sense. It also contributes a nourishing quality that benefits drier and photo-aged skin types.

The formula uses extracts from two species of honeysuckle, Lonicera caprifolium and Lonicera japonica, as a natural preservation system. These extracts are commonly used in professional formulations as a gentler alternative to parabens and synthetic preservatives. O-cymen-5-ol also contributes antimicrobial support to help keep the formula stable and safe for use.
