What you get: A beginner-friendly Retinol serum that targets early signs of ageing 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.

  • Before and after showing results of Retinol Serum Duo
    "So I must tell you my skin used to look really dull and highly pigmented. I came across your products specially having acne scars and spots I thought of going with Retinol Serum and Vitamin C Serum, and now I can't believe how my skin looks. It just boosted my confidence and makes me feel sooo good. Thank you!"

Reviews Summary
Customers say this serum is gentle and effective, with many reporting smoother, plumper skin and reduced fine lines after several weeks of use. Users appreciate the lightweight, non-greasy texture that absorbs well and works well for sensitive skin. Many mention starting slowly with twice-weekly application before building up frequency. Common feedback includes improved skin radiance, firmness, and reduced appearance of wrinkles around eyes and forehead. Some note an unpleasant acidic or chemical smell, while others find the runny consistency challenging to dispense. A few users report no visible results after months of use, but most praise its gentleness and value for money.
