What's in the kit and what does each product do?

Hydroxy Cleanser: A soap-free, pH-balanced cleanser (pH 4.5–5) that removes impurities without disrupting the skin barrier or stripping hydration. It contains low concentrations of Glycolic Acid, Lactic Acid, and Salicylic Acid to gently prep the skin surface and keep it receptive to the actives that follow.C Forte: A morning serum with 16% L-Ascorbic Acid (Vitamin C), Vitamin E, and Ferulic Acid. L-Ascorbic Acid is one of the most studied antioxidants in skincare — it neutralises free radicals generated by UV exposure, inhibits melanin production, and supports collagen synthesis. Ferulic Acid has emerging evidence suggesting it enhances the stability and effectiveness of Vitamin C, which matters because L-Ascorbic Acid is notoriously prone to oxidation. The airless, opaque packaging exists for exactly this reason.Zinc Shade: A broad-spectrum SPF 15 matte day cream using Zinc Oxide. UV exposure is the single biggest driver of extrinsic skin aging — without daily sun protection, the other actives in this kit are working against a headwind. Applied over C Forte each morning.Smooth Serum: A night serum with Glycolic Acid (3%), Lactic Acid (1%), and Gluconolactone (1%). Alpha-hydroxy acids increase the rate of surface cell turnover, which improves skin texture, supports more even pigmentation, and helps other actives penetrate more effectively. Use this before Ultimate A Gold at night.Ultimate A Gold: The centrepiece of this kit. A night cream combining Retinal (Vitamin A), Niacinamide, Lactobionic Acid, 4-n-Butylresorcinol, Ceramides, Hyaluronic Acid, and Ectoin. Retinal converts to retinoic acid in the skin and has the strongest evidence base of any cosmeceutical ingredient for improving skin texture, cell turnover, and fine line appearance. The supporting cast of Niacinamide (barrier support and pigment inhibition), Ceramides (barrier repair), and 4nB (tyrosinase inhibition for pigmentation) means this product addresses multiple aging concerns in a single step.

Retinal

Also known as Vitamin A, Retinal is a next-generation retinoid used in skincare to help refine skin texture and improve the appearance of uneven tone and visible signs of ageing. It’s well tolerated and suitable for most skin types, including those that find traditional retinoids too harsh.

Niacinamide

Also known as Vitamin B3. Niacinamide is a well-studied ingredient that helps maintain a healthy skin barrier and supports an even-looking skin tone. It is well tolerated and suitable for all skin types, making it a versatile addition to many skincare formulations.

Glycolic and Lactic Acid

Also known as Alpha Hydroxy Acids. Glycolic and Lactic Acid exfoliate and smooth the skin surfaces.

L-Ascorbic Acid

Also known as Vitamin C, L-Ascorbic Acid (Vitamin C) is a well-studied antioxidant that helps improve the appearance of uneven skin tone and supports smoother-looking skin.

4-n-butylresorcinol

4-n-Butylresorcinol helps improve the appearance of pigmentation and supports an even-looking skin tone.

Ferulic Acid

Ferulic acid’s emerging evidence suggests it can improve the effectiveness of Vitamin C and help to reduce the appearance of fine lines and wrinkles.

Ceramides

Emerging evidence suggests that smaller ceramides support the skin’s surface and help maintain hydration and the appearance of a healthy skin barrier.

Hyaluronic Acid

The optimum size of Hyaluronic Acid for skincare is still a topic of research. Emerging evidence suggests that medium-size HA can support skin hydration and help improve the appearance of skin smoothness and plumpness.

Lactobionic Acid

Lactobionic Acid is a Polyhydroxy Acid (PHA) that works as a gentle exfoliant and humectant. It helps to smooth skin texture and improve the appearance of dullness without the irritation often associated with stronger acids. PHAs like Lactobionic Acid also attract moisture, supporting hydrated and visibly refreshed skin.
