Es la tercera vez que compró esta vitamina C y ¡me encanta! He probado muchos sérums de vitamina C, de todas las texturas, concentraciones y precios del mercado, y me quedo con este sin duda. Después de ser muy constante, este año he conseguido con este sérum difuminar mis manchas del sol. Además, me encanta su olor, su textura de aceite seco que se absorbe rápido, y no ensucia tanto la piel y los poros como otros que se oxidan muy rápido al contacto con el aire y la luz. Mi madre se ha comprado su versión Advanced tipo gel y también está encantada.

Ik ben echt mega blij met dit product. Allerlei dure merken heb ik geprobeerd, waarbij ik netjes alle stappen aanschaf en de stappen opvolg maar echt geen resultaten zie. Dit Serum heeft mij na 7 dagen laten zien dat het werkt. Mijn pigment vlekken en rode vlekken op huid en decolleté zijn écht stukken lichter en op sommige plaatsen al verdwenen. Het is echt een dikke 10!

Primera vitamina C que uso y mi piel sensible no se ha quejado. Se absorbe rápido, todavía no he visto resultados

With summer in full effect I swapped the daily radiance 2-1 moisturizer to something a bit lighter and with higher SPF. I found I was missing the vitamin C so ordered this trial size which is actually a lot of product in that little bottle, just a couple of drops on each side of the face… it goes on really smooth absorbs nicely lovely citrus sent and then I layer with my clarity, peptides and moisturizer on top. A great way to keep C tetra in if you find the daily radiance a bit heavy on your face

Unlike other vitamin C serums that I’ve used, I’ve experienced no burning with C-Tetra. C-Tetra is very light on my skin and doesn’t make it feel heavy. Skin feels bright. Other products I’ve used cause “pilling” when my face cream was applied. There is no pilling with C-Tetra.

Muy bueno. Es muy líquido a la hora de aplicarlo me gustaría que fuese un pelín más denso para que se pudiera aplicar más cómodo pero en cuanto a eficacia es fabulo. Estoy encantada

C-Tetra is one (of many) of my favorite products from Medik8. To have it available now in a travel size is fantastic! Great product. Highly recommended.
