Geek & Gorgeous 101 C-Glow - 15% Vitamin C Serum, super-light + Ferulic acid & vitamin E, gives environmental protection, boost collagen & evens skin tone - all skin types, 30ml

Best value for money Vitamin C serum. I’ve repurchased this serum many times before from Amazon and it comes fresh and clear every time. It’s a serum which I’ve found to give brightening and effective results almost immediately and layers well with my other skincare. I have dry skin but I find this product soaks into my skin quickly as it’s very watery and doesn’t irritate my skin. One thing to note is that because Geek & Gorgeous tends to make their products in batches, the serum doesn’t last long. However, if you keep your vitamin c serum in your fridge and take out a small amount each time, then it’s no issue. I’ve got a smaller 5ml bottle which I pipette the serum into and keep refilling as I need from the original bottle. This helps keep the product lasting for awhile. A small price to pay for such a good value product.

Really great product and excellent value for money. It’s lightweight and feels very comfortable to use, no irritation at all. I’d love to try more of their products in the future and will definitely purchase again. It’s been 10 days since I started using it, and I’ve already seen significant improvemen.

I’ve tried quite a few vitamin C serums and this one has become one of my favourites. The texture is super lightweight, sinks in quickly, and doesn’t leave my skin feeling sticky or oily. After a few weeks of use, my skin looked brighter, smoother, and a bit more even overall. It layers really well with the rest of my skincare and sits nicely under makeup too. One tip: keep the bottle in the fridge after opening to help keep the vitamin C fresh for longer. I use it in the morning before moisturiser and SPF. For 30ml, I think it’s great value for money and feels much more expensive than it is. Really happy with it so far!

Lightweight, fast‑absorbing, and effective. The 15% vitamin C really brightens my skin, and the ferulic acid + vitamin E make it feel more stable and potent. Great daily antioxidant serum.

There is no doubt this benefits the skin in terms of brightness. It has a consistency like water. Very mild 'hot dog water' smell as per all unscented Vitamin Cs, but not a strong as some and very tolerable. The reason for my 3 stars is it makes my skin feel sticky despite going on smoothly.

The best most affordable version is L-absorbic acid on the market! The ingredients are almost a perfect dupe of the skinceuticals serum! Amazing find, highly recommend.

Very good quality pure vitamin C, not too strong but it does sting a bit. It arrived completely clear and in date, I kept it in the fridge and it stayed completely fresh until I used it up. The price is also very reasonable, so it is great for a pure fresh vitamin C that is not too irritating. I didn't use it long enough to notice any brightening effects as such, but compared to other vitamin C serums I have used, this was less irritating and easy to incorporate into my routine.

Hi, I tried this product only once, and my skin started itching and burning. Please don’t use this product if you have acne or sensitive skin. I’m trying to return it, but it’s not eligible under the return policy. I feel stuck now since I spent £24 on this product after reading all the positive comments.

It is very successful to contain 15% vitamin C. I love to use it

Llevo tiempo usando este suero y estoy encantada. La relación calidad/precio es de 10. Es una fórmula muy ligera, casi como agua, que se absorbe enseguida y deja la piel luminosa, más uniforme y con ese efecto “buena cara” que todas buscamos. Hay que guardarla en el frigorífico y, si no me equivoco, dura unos 2 meses. Pero a diferencia de otras marcas más caras (tipo La Roche-Posay), cuando toca tirarla porque se ha oxidado, no duele tanto, porque el precio es mucho más asequible. Y lo mejor: nunca me ha causado irritación ni reacción rara, cosa que sí me ha pasado con otros sueros de vitamina C. Es ideal para pieles sensibles, y que al llevar ácido ferúlico y vitamina E, potencia el efecto antioxidante sin añadir grasa ni pesadez. También ayuda a mejorar el tono desigual y a prevenir el daño ambiental, algo que se nota con el uso constante. Si estás buscando una vitamina C eficaz, bien formulada y que no te vacíe el bolsillo, esta es una opción fantástica. Yo ya la he recomendado a varias amigas y todas han repetido.

wodnista konsystencja, dla mnie to bardzo ważne. Chyba najlepsze w tym przedziale cenowym.
