Renewal That Works Around The Clock

The Ammuri 24-Hour Retinol 5% Serum with Apple Stem Cell is a high-performance anti-ageing treatment formulated for those ready to take their skincare seriously. Combining one of dermatology's most studied actives — Retinol — with the regenerative potential of Apple Stem Cell technology, this serum works continuously to support skin renewal, visibly reduce the signs of ageing, and restore a firmer, more youthful-looking complexion.

This is not a quick fix. It is a long-term investment in your skin's future.

Why Apple Stem Cell Technology Sets This Serum Apart

Most retinol serums stop at Vitamin A. This one goes further.

The Apple Stem Cell Extract in this formula is derived from a rare, long-lived Swiss apple variety — Uttwiler Spätlauber — specifically selected for its exceptional cellular longevity. In skincare research, this extract has been shown to help protect the vitality of skin's own stem cells, which are responsible for generating new, healthy skin tissue.

As we age, skin stem cell activity naturally declines — leading to slower renewal, loss of firmness, and the gradual deepening of lines. Apple Stem Cell Extract works at this foundational level, supporting the skin's capacity to regenerate from within. Paired with Retinol's proven ability to accelerate surface cell turnover, the result is a dual-action approach: renewal from the surface down, and resilience from the cellular level up.

This is what separates the 24-Hour Retinol Serum from a standard retinol product.

Ingredient Spotlight

Retinol 5%
One of the most extensively studied ingredients in skincare, Retinol is a Vitamin A derivative that accelerates skin cell turnover, stimulates collagen production, and visibly reduces the appearance of fine lines, wrinkles, and uneven skin tone.

Apple Stem Cell Extract
Derived from the rare Uttwiler Spätlauber Swiss apple, this extract supports the longevity and vitality of skin stem cells — the foundation of healthy skin renewal. It works synergistically with Retinol to enhance the skin's natural regenerative processes at a cellular level.

Hyaluronic Acid
A powerful humectant that draws moisture into the skin and helps retain it throughout the day and night, counterbalancing the potential drying effect of Retinol.

Niacinamide (Vitamin B3)
Supports the skin barrier, minimises pore appearance, and helps reduce redness and uneven tone.

Peptides
Short-chain amino acids that signal the skin to produce more collagen and elastin, contributing to improved firmness and resilience over time.

How To Use

Evening Routine (PM) — Primary Application

1. Double cleanse to remove SPF and impurities
2. Apply toner or essence if used
3. Dispense 3–4 drops onto fingertips
4. Press gently into skin — do not rub or drag
5. Follow with a nourishing night moisturiser or facial oil

If new to Retinol, begin with evening use only, 3 nights per week. Gradually increase to nightly use as your skin builds tolerance over 4–6 weeks.

Results Timeline

Weeks 1–2: Skin may experience a brief adjustment period — mild dryness or sensitivity is normal.
Weeks 3–4: Skin texture begins to feel smoother. Early improvement in radiance and tone becomes visible.
Weeks 6–8: Visible reduction in fine lines and improved skin firmness.
Long-term: The most significant anti-ageing results are seen at the 3–6 month mark and beyond.

Complete Your Anti-Ageing Routine

Frequently Asked Questions

Is 5% Retinol suitable for beginners?
If you are new to Retinol, start slowly — use every third evening for the first two weeks, then build to nightly use over 4–6 weeks.

Can I use this with other actives?
Retinol pairs well with Hyaluronic Acid and Peptides. Avoid AHAs, BHAs, or Vitamin C in the same application. Use Vitamin C in the morning and Retinol in the evening.

Why is SPF so important with Retinol?
Retinol increases skin cell turnover, making skin more sensitive to UV radiation. Daily SPF 50 is non-negotiable.

Can I use this during pregnancy or breastfeeding?
No. Retinol is not recommended during pregnancy or breastfeeding.
