goop Exosome Hydration Therapy Serum — 1.0 fl oz Hydrating Gel with Cica Leaf Exosomes & Polyglutamic Acid for Plump, Smooth Skin

This serum combines plant-derived exosomes with polyglutamic acid, hyaluronic acid, red sea moss, and snow mushroom in a viscous, cooling gel designed to boost skin hydration and support the barrier. The formula targets dryness and sensitivity by attracting and holding water in the skin while forming a protective layer that helps skin feel softer and appear plumper. Clinical testing on a sample group showed substantial immediate hydration and improved elasticity after short-term use.

How does the exosome technology help my skin?

Exosomes in this product are sourced from cica leaf and incorporated to deliver concentrated plant-derived signalling components within a hydrating base. They are paired with humectants so the skin retains water more effectively, which can reduce the look of tightness and fine dryness lines.

• Over 3 million cica leaf exosomes per bottle for targeted delivery.
• Clear gel texture disperses exosomes evenly across the skin.
• Works with humectants to maximize moisture retention.

What ingredients deliver and lock in moisture?

This serum uses a trio of hydrators—hyaluronic acid, polyglutamic acid (PGA), and snow mushroom—alongside red sea moss to both attract and seal in water. PGA can hold more moisture than hyaluronic acid, while red sea moss and snow mushroom contribute antioxidant and film-forming benefits that help maintain surface hydration.

• Hyaluronic acid: immediate water-binding humectant.
• Polyglutamic acid: long-lasting moisture retention and plumping support.
• Red sea moss & snow mushroom: create a protective, smoothing layer.

How do I include this serum in my routine and how often should I use it?

Use one to two drops applied to clean skin on the face and neck before your moisturizer, morning and night. The gel texture layers well under creams and sunscreen without pilling, and a small amount spreads broadly, so a little goes a long way.

• Apply after cleansing and any lightweight treatment serums.
• Follow with moisturizer and SPF in the morning.
• Use twice daily for consistent hydration results.

What results can I expect and when will I see them?

Clinical measurements on a sample cohort showed a large immediate increase in skin hydration after a single use and measurable elasticity improvements within a week. Individual results vary by skin type, baseline condition, and full routine compliance.

• Immediate hydration boost reported in clinical testing.
• Improved skin elasticity observed after short-term use.
• Best results when used consistently with moisturizer and sun protection.

Who is this for: goop Exosome Hydration Therapy Serum is formulated for people seeking a high-performance hydrating step that calms sensitive or irritated skin, supports barrier repair, and enhances plumpness and smoothness.
