Description

Restore the look of skin radiance in just 7 days* with cult-favourite C-Tetra.

Formulated with a stabilised form of vitamin C (7%) called tetrahexyldecyl ascorbate (pronounced 'tetra-hexul-deckul as-CORR-bate'), this lightweight serum works to visibly brighten uneven skin tone and reduce the look of fine lines and wrinkles, while remaining gentle on sensitive skin.

Fortified with vitamin E, this antioxidant powerhouse also protects the skin against the ageing and damaging effects of free radicals for a more youthful and healthy-looking complexion overall. The perfect option for those who are new to vitamin C, or those with sensitive skin.


*Proven via independent consumer study conducted over 4 weeks on 52 participants with sensitive skin.

Comfortable, Supportive, and Worth Every Dollar
Color: Black, Item Shape: Classic, Color: Black, Item Shape: Classic
I didn’t realize how much tension I was carrying in my legs and lower back until I started using this footrest. The memory foam is firm but comfortable — it doesn’t flatten out like cheaper ones. I love that it’s height-adjustable, so I can customize it depending on how I’m sitting. It instantly improved my posture and took pressure off my hips and lower back, especially during long desk and gaming sessions. The build quality feels premium, it stays in place on the floor, and the cover is soft and easy to clean. After using it for a few days, I noticed less stiffness and way better overall comfort while sitting. If you spend hours at a desk, do yourself a favor and get this. Simple upgrade, huge difference. Highly recommended.

Foot rest
Color: Gray, Item Shape: Classic
It's very sturdy. It's very comfortable. It's not too soft. It's not too hard. I like it. I flip it when I sit in my chair when I'm on my iPad I can use the lower level when I'm relaxing. I flip it over and I use the the round part of it. It's just perfect for me.. I have plantar fasciitis and it really helps the heels of my feet.

Good product.
Color: Black, Item Shape: Classic
It is helpful for sure. I had knee surgery and this helped me keep my knee comfortable while working. I wish it was able to raise my leg up a bit more but for the price this is fine.

Great for short peeps!
Color: Gray, Item Shape: Teardrop
the best for a too tall desk or table or not correct height chair. 5’3, always too short for things and this has definitely helped since working at home! super soft too and different surfaces and heights!
