The INKEY List Ectoin Hydro-Barrier Serum, Lightweight Daily Hydration — 2% Ectoin & 2.5% Hyaluronic Acid for Plumper Skin

The INKEY List Ectoin Hydro-Barrier Serum is a lightweight, dual-action serum that hydrates skin and supports a healthier skin barrier using ectoin, multi-weight hyaluronic acid and a barrier complex.

This serum combines targeted moisture delivery with barrier-supporting actives to help skin look plumper and feel more resilient. Its milky, fast-absorbing texture layers easily under creams and makeup and is designed for everyday AM and PM use. Formulated to lock in hydration quickly and help restore barrier function, the product is suitable for a wide range of skin types and routines.

How does this serum increase hydration so skin feels bouncier?

The formula uses a multimolecular hyaluronic acid system at 2.5% to attract and hold moisture at different skin levels while 2% ectoin further supports water retention and cellular hydration. Together these ingredients help improve immediate and sustained skin moisture, creating the appearance of plumper, smoother skin.

• 2.5% multi-weight hyaluronic acid for surface and deeper hydration
• 2% ectoin to support moisture preservation and cellular resilience
• Light, milky texture that spreads and absorbs quickly

What does the barrier complex do and how fast will I notice changes?

The 1% Barrier Complex is formulated to reinforce the skin’s natural protective layer and improve moisture retention. In consumer testing, users reported quicker hydration and visible improvements in texture within days, while ongoing use supports stronger barrier function over time.

• 1% Barrier Complex to aid barrier repair and moisture locking
• Visible improvements in hydration and texture reported in short-term studies
• Designed to be layered under moisturisers and sunscreen without pilling

How should I use this serum in my daily routine?

Apply the serum twice daily after cleansing as your first serum step, both morning and evening. Use a pea-sized amount for face and neck, pressing it into slightly damp skin to maximise hydration, then follow with any targeted treatments and a moisturiser to seal benefits; always finish with SPF in the morning.

• Use AM and PM after cleansing — apply to damp skin for best results
• Pea-sized amount for face and neck; pat in gently
• Layer under treatment serums, moisturiser and SPF (AM)

Is this serum suitable for sensitive or combination skin?

The lightweight, non-tacky formulation was designed to suit a broad range of skin types, including sensitive, dry and combination skin. Its focus on hydration and barrier support reduces the likelihood of irritation, but those with very reactive skin should patch-test new products as a precaution.

• Milky, fast-absorbing texture that won’t feel heavy on combination skin
• Targets redness, dryness and dullness associated with compromised barriers
• Patch-test recommended for highly reactive skin

Who is this for: The INKEY List Ectoin Hydro-Barrier Serum is for anyone wanting to boost hydration and strengthen their skin’s barrier without a heavy finish — ideal for people experiencing dryness, dullness, sensitivity tied to a weakened barrier, or anyone who wants a reliable everyday serum that layers well under moisturisers and makeup.
