What It Is

This high-strength 5% retinol serum is designed for experienced users seeking intensive anti-ageing and skin renewal results. It supports the skin's natural overnight renewal process to visibly reduce fine lines, wrinkles, and uneven texture while improving tone, radiance, and firmness. Hyaluronic acid helps maintain skin hydration and comfort as your skin adjusts to this advanced formula.

What It Does

• Visibly reduces the appearance of fine lines and deeper wrinkles with consistent use
• Accelerates skin cell turnover for faster texture improvement and radiance
• Stimulates collagen production to improve skin firmness and elasticity
• Fades the appearance of dark spots, pigmentation, and post-acne marks
• Refines pores and smooths uneven skin texture
• Hyaluronic acid supports hydration and comfort during the adjustment period

Who It's For

Designed exclusively for experienced retinol users who have built tolerance over several months at lower concentrations (2.5%–3.5%). Ideal for those in their 40s–50s targeting more significant signs of ageing, or anyone who has plateaued at lower strengths and wants maximum renewal. Not recommended as a starting point — always build up through 2.5% and 3.5% first.

How to Use

Evening only (retinol breaks down in sunlight). Apply 2–3 drops to clean, dry face and neck. Follow with a rich moisturiser. Always apply SPF 30+ the following morning — our Vitamin C Day Cream SPF50 is the ideal morning companion. Begin with 2–3 nights per week and increase to nightly as your skin builds tolerance.

Frequently Asked Questions

Is 5% retinol safe to use?
Yes, when used correctly by experienced retinol users. Our encapsulated formula releases retinol gradually to reduce irritation risk. Always start 2–3 nights per week and build up slowly.

Can beginners use this?
No — this is an advanced formula. Beginners should start with our Retinol 2.5% Serum and build tolerance over several months before stepping up.

Do I need SPF with retinol?
Yes — always. Retinol increases photosensitivity. Apply SPF50 every morning without exception. Our Vitamin C Day Cream SPF50 makes this easy.
