How it works

Vitamin C is a potent antioxidant that helps reduce the visible effects of environmental damage and promotes a more luminous complexion. MSM (methylsulfonylmethane) is a sulfur-containing compound that can support skin’s structure and texture. Together they help promote an even tone, reduce the appearance of dullness, and encourage smoother-looking skin.

Ideal for

• Dull, uneven or tired-looking skin
• Skin showing early signs of hyperpigmentation or sunspots
• Anyone looking to add antioxidant protection to their routine
• Most skin types (introduce gradually if you have sensitive skin)

Directions for use

1. Cleanse and tone.
2. Apply 2–3 drops of serum to face and neck, gently patting until absorbed.
3. Follow with your moisturizer. In the morning, always finish with broad-spectrum sunscreen.
4. Start by using every other day if you have sensitive skin, then increase to once or twice daily as tolerated.

Texture & packaging

• Lightweight, clear/serum texture that layers well under other skincare and makeup
