Smooth and Stellar were designed to work better together — delivering visible results in just two effortless steps. Smooth uses high molecular weight hyaluronic acid to draw moisture into the skin, plump fine lines, and boost elasticity. Stellar, a clinically backed blend of antioxidant-rich oils, seals it in and strengthens the lipid barrier with ingredients proven to improve firmness, calm inflammation, and reduce signs of fatigue. Hydration meets nourishment. The result: skin that feels calm, looks radiant, and gets stronger over time.

Your skin barrier, supported from the first layer

The Skin Barrier Duo combines two powerful layers:
Smooth Serum delivers deep hydration with hyaluronic acid to plump and soften the skin. Stellar Serum seals it in with antioxidant-rich oils like prickly pear and vitamin K — calming inflammation, locking in moisture, and supporting a resilient skin barrier.

This two-step routine is made with natural ingredients your skin actually recognizes and absorbs. Whether you're streamlining your routine or building one for the first time, this pair works beautifully its their own or alongside the products you already love. Calm, hydrated, glow-worthy skin — no complicated steps required.

KEY INGREDIENTS

SODIUM HYALURONATE – plant-derived hyaluronic acid that draws moisture into the skin and holds it there, helping to visibly plump and hydrate.

PRICKLY PEAR SEED OIL – deeply nourishing and rich in antioxidants; ideal for sensitive or reactive skin.

ROSEHIP OIL – supports skin regeneration and elasticity with natural vitamin A and essential fatty acids.

BERGAMOT OIL – Known to help reduce cortisol levels when inhaled; offers a calming, mood-lifting effect during application.

STEP 1

Apply 3 drops of Smooth Serum to damp skin.
Hyaluronic acid acts like a moisture magnet — it draws hydration into the top layer of skin, plumps fine lines, and leaves your complexion smooth and fresh.

STEP 2

Follow with a few drops of Stellar Serum to seal in hydration and nourish the skin barrier.
Inhale clary sage, bergamot and frankincense to balance your mood and lower cortisol levels.

For most people these products will last 3-4 months if you use them daily.
If can be for both. Or either. The Smooth and Stellar is very effective in the morning as it sets you up for the day, plumping and hydrating skin while the Stellar moisturises and protects skin. As a nighttime routine, Smooth infuses skin with hydration (and we lose the most water through our skin at night) and the Stellar is an excellent night serum. Whatever works for your schedule and preferences.

The Smooth is a water-based hyaluronic acid that adds and holds hydration. The Stellar is a facial oil that will seal in that moisture as well as nourish and protect your skin. Smooth is your hydrator, Stellar is your moisturiser. They work synergistically to deliver glowing skin.
