What you get: A beginner-friendly Retinol serum that targets early signs of aging and uneven skin tone - without the irritation.

Why it works: 1% slow-release Retinyl Acetate gently boosts cell turnover to smooth fine lines, wrinkles and pigmentation. Squalane adds hydration and helps calm the skin.

How it feels: Lightweight, silky and non-greasy. Skin feels soft, nourished and gradually more even over time.

When to use: PM only, 2–3 nights a week to start. Once skin builds tolerance, you can move up to our 1% Scar, Mark and Wrinkle Solution.

    Effective but a bit runny so it's a little messy getting it from the bottle
