For anyone who's given up on oils because they felt heavy, greasy, or caused breakouts, this changes the equation.

What it does for your skin:

  • Absorbs completely — no greasy residue, no heavy finish
  • Leaves skin looking smoother and more luminous
  • Preps a hydrated base so makeup goes on smoother and lasts longer
  • Gentle enough for reactive, rosacea-prone, and sensitive skin

Fragrance-free. Formulated by a licensed esthetician.

  1. Shake well before each use.
  2. Apply after Water Elixir, while skin is still slightly damp.
  3. Warm one pump between palms and press into face and neck — don't rub.
  4. Follow with Water Balm (AM) or Intense Barrier Cream (PM).
  5. Use morning and evening. Two pumps in dry winter months.

Scared of Face Oil? This One’s Different.

Peptide serum meets featherlight facial oil for skin that looks fresher, juicier, and better under makeup.

1. Shake well

Shake before every use to evenly blend the oil and water phases.

2. Warm between palms

Warm one pump between your palms so it spreads smoothly and absorbs evenly.

3. Press Into Damp Skin

Press into skin while it is still slightly damp from Water Elixir.

For extra-dry skin, use the Skin Prep Brush in light, upward strokes for a smoother, more even application.

4. Seal It In

Follow with Water Balm in the morning or Intense Barrier Cream at night.

It’s Not Just an Oil
