Hyaluronic Acid Complex

Hydrate • Plump • Support

Hyaluronic acid is a naturally occurring substance found within the skin with an exceptional ability to bind water. Because the molecular size of hyaluronic acid influences how it interacts with the skin, combining different forms and molecular weights can provide a more comprehensive approach to hydration.

The 4D+ complex utilizes multiple forms and molecular weights to support both immediate surface hydration and longer-lasting moisture retention.

• High Molecular Weight Hyaluronic Acid

Primarily supports hydration at the skin’s surface, helping create a smoother feel while supporting the moisture barrier.

• Mid Molecular Weight Hyaluronic Acid

Helps maintain hydration and supports the skin’s natural moisture balance.

• Low Molecular Weight Hyaluronic Acid

Provides hydration within the more superficial layers of the skin, complementing the surface activity of larger HA molecules.

• Sodium Hyaluronate

A salt form of hyaluronic acid valued for its ability to attract and hold water. It helps reduce the appearance and feel of dryness and flaking while contributing to softer, more supple skin.

Picea Abies - Norway Spruce Extract

Soothe • Comfort • Support

Derived from Norway spruce, Picea abies extract provides botanical support for stressed and sensitized skin. Its soothing properties make it particularly valuable in a hydration formula intended for sensitive skin and post-treatment care.

Organic Botanical Antioxidant Blend

Protect • Soothe • Nourish

A blend of organic horsetail, hibiscus, pomegranate, dandelion, and bilberry extracts provides naturally occurring antioxidant compounds that help support skin exposed to everyday environmental stressors.

• Horsetail - Equisetum arvense

A mineral and antioxidant-containing botanical traditionally valued in skin-supportive preparations.

• Hibiscus - Hibiscus sabdariffa

Rich in naturally occurring plant compounds and antioxidants that complement a bright, healthy-looking complexion.

• Pomegranate - Punica granatum

A polyphenol-rich fruit extract that provides antioxidant support against environmental oxidative stress.

• Dandelion - Taraxacum officinale

A botanical source of antioxidant compounds used to support and condition the skin.

• Bilberry - Vaccinium myrtillus

Naturally rich in anthocyanins and other polyphenols that provide antioxidant support.

Apply to freshly cleansed, slightly damp skin, gently massaging over the face, neck, and décolleté morning and evening after cleansing and toning. Follow with additional treatment products and moisturizer.

When using exfoliating acids or retinoids, apply 4D+ Hyaluronic Serum first, then continue with your treatment products. Follow with moisturizer to help maintain hydration.

During the day, complete your morning skincare ritual with Mineral Tinted SPF 30.

Think of hyaluronic acid as a water magnet rather than a moisturizer itself.It attracts and holds water within the skin, while your moisturizer provides the emollient and/or occlusive components that help reduce moisture loss. Pairing the two creates a more complete hydration ritual.

For particularly dehydrated skin, mist with Ginseng Mineral Toner to lightly dampen the skin, then apply 4D+ Hyaluronic Serum. Follow with Ceramide+ Bioshield Crème for additional barrier support, then layer Radiant Antioxidant Moisture Crème to complete your hydration ritual.

Can I use it every day?

Yes. 4D+ Hyaluronic Serum is designed for twice-daily hydration and can be incorporated into both morning and evening routines.

Is it only for dry skin?

No. Dehydration refers to a lack of water within the skin and can occur in dry, normal, combination, and oily skin types. Even oil-rich skin can benefit from appropriate hydration.

Can I use it with retinoids or exfoliating acids?

Yes. Apply 4D+ Hyaluronic Serum first to provide a hydrating layer before your exfoliating acid or retinoid, then continue with the rest of your ritual. This can be especially helpful when using active products that may contribute to dryness or dehydration.

Can I use it on sensitive skin?

The formula is designed to be suitable for sensitive and easily stressed skin. As with any new skincare product, individual sensitivities can occur, so patch testing is recommended when appropriate.
