The Key Four is a simple, science-led routine designed to support the essential needs of healthy skin - cleansing, hydration, protection and targeted treatment.

Suitable for all skin types and life stages, these four products work together to strengthen the skin barrier and support consistent, visible results.

This bundle is perfect for anyone new to Skingredients and wanting to build a consistent skincare routine and contains:

This bundle includes:

PreProbiotic Hydrating Cleanser: A gentle, hydrating daily cleanse that removes oil, SPF, pollution and makeup without stripping the skin. Powered by prebiotics, probiotics and polyhydroxy acid (PHA), it supports the skin barrier, reduces dehydration and helps keep dullness at bay. Non‑comedogenic and barrier‑friendly.

Skin Veg Hyaluronic Acid Serum: Daily hydration serum with hyaluronic acid, antioxidants, and pro-collagen peptide. Use twice daily to rehydrate tight, dull skin, smooth fine lines caused by dehydration and boost brightness.

Skingredients Skin Protein Anti-Ageing Retinoid Serum: A multi‑tasking anti‑ageing serum with retinyl palmitate, a gentle form of vitamin A. It supports collagen, improves texture, reduces dullness and helps balance oil. Ideal for softening fine lines and keeping skin strong and smooth.

Skin Shield SPF50 PA+++: A high‑protection, mineral SPF that defends against UV damage while giving the skin a natural glow. Ideal for sensitive or reactive skin, this smoothing formula doubles as a primer, helping simplify your morning routine without compromising protection.

Our 90-day Skin Confidence Guarantee

We're so confident in the Key Four, we're offering a 90-day money-back guarantee for customers!*
