Philosophy of Flowers

Irish Sea Moss, Raw Bull Kelp, Wild Marshmallow Root, Bog Myrtle, and Dulse Sea Blossom come together in a marine-floral blend that restores balance and harmony to the skin.

How to Use – The Ritual

After cleansing, mist your face with toner or flower water. While the skin is still slightly damp, press 3–5 drops of serum into the face, neck, and décolleté. Massage gently in circular motions until fully absorbed.

Use daily, morning and evening. For extra nourishment or repair, follow with your favorite facial balm or serum concentrate.

Active Botanicals

Irish Moss

Sustainably hand-harvested from the pink sandy shores of Prince Edward Island and the coast of Nova Scotia. You may notice light brown sediment in the bottle — this is the natural sea moss extract. Its silky texture delivers a rich source of calcium, sulfur, magnesium, potassium, vitamin A, and vitamin K. Irish Moss helps soften the look of fine lines, deeply hydrate the skin, and protect against environmental stress. It is non-comedogenic and naturally rich in mucilage, making it ideal for dry and irritated skin.

Dulse & Bull Kelp

These nutrient-dense seaweeds are packed with vitamins and minerals. Ethically hand-foraged, they help feed the skin with essential phytonutrients that support a fresh and radiant complexion.

Hibiscus Flower

Known for its natural firming and toning properties. Hibiscus contains alpha-hydroxy acids (AHAs) that encourage gentle exfoliation and cellular renewal. It helps improve elasticity and supports clearer-looking skin.

Marshmallow Root

A natural humectant that attracts and holds moisture in the skin. Rich in flavonoids and soothing plant compounds, marshmallow root supports hydration while helping to calm and protect the skin from environmental stress.

All ingredients are organic, wild-crafted, sustainably harvested, ethically sourced, and regionally selected to ensure the highest quality.
