✨ Meet Medik8 C-Tetra Advanced — vitamin C, but seriously upgraded. ✨
If brighter, smoother, more even-looking skin is on your wish list, this is one we are VERY excited about at Angela Kay’s. 💚
C-Tetra Advanced is Medik8’s next-generation vitamin C serum, combining:
🍊 20% stabilised vitamin C
🌿 Phyto exosomes to support skin resilience
✨ Acetyl zingerone, a powerful antioxidant that helps defend against free-radical damage
And the clinical results are pretty impressive…
💚 100% saw visibly brighter skin in just 7 days
💚 100% noticed visible improvements in skin tone and hyperpigmentation in 7 days
💚 Clinically proven to visibly reduce wrinkles in 7 days
💚 Clinically proven to leave skin visibly smoother in 7 days
💚 0% barrier disruption in the independent clinical study
💚 Scientifically proven to reduce pollution-related damage to the skin’s surface by up to 90%
So you get high-performance vitamin C without the idea that stronger automatically has to mean harsher.
It’s perfect for helping to target:
✨ Dullness
✨ Uneven skin tone
✨ Pigmentation
✨ Fine lines and wrinkles
✨ Uneven texture
✨ Environmental damage and premature ageing
And it has a beautiful lightweight gel-serum texture, so it fits easily into your morning skincare routine before moisturiser and SPF.
Even better at Angela Kay’s…
