Vitamin C provides antioxidant protection, protecting the skin from the damage of free radicals in the environment like UV light and pollution. Vitamin C can help reduce hyperpigmentation and red spots and maintain collagen and elasticity, thus helping wrinkles.

Depending on the form, vitamin C can be unstable and irritating. It is sensitive to heat, light and oxygen.

I have never used a vitamin C product for my skin previously and after looking at different brands and products, I bought Medik8 CE-Tetra. Medik8 is a British professional grade skincare company with roots in science and technology to manufacture effective and stable products.

The Medik8 CE-Tetra is targeted towards those with normal, dry and redness-prone skin. I have oily skin, but purchased this as the oil-free vitamin C product targeted to oily skin was more expensive.

This product comes in an amber glass bottle to protect it from light and dispenses from a dropper. The first ingredient, jojoba seed oil, derived from the jojoba shrub, is a source of fatty acids that the skin recognizes and can use to help the skin repair itself, defend against UV light and stimulate collagen production. It is noncomedogenic and is fast-absorbing. Next are two silicones, cyclopentasiloxane and cyclohexasiloxane. Silicones are used in skincare as conditioning and lubricating agents, providing slip and giving the skin a silky feeling. I don’t usually like using skincare with silicones; I find my skin feels heavier or extra oily when I do. However, this has been in moisturizing lotions and lotion sunscreens, which I no longer use on my face. A serum with silicones probably won’t feel as heavy. Next is the vitamin C form tetrahexyldecyl ascorbate (7%). This is a mild vitamin C derivative that is stable in light and air for up to 18 months. It is oil soluble and used in skincare for brightening, collagen production and repairing and preventing effects of environmental damage. On the box, it says that this form of vitamin C has the equivalent potency of 28% L-ascorbic acid (which is unstable). There is tocopheryl acetate (vitamin E). Vitamin E and vitamin C are used together to prevent UV damage, therefore indirectly increasing the efficacy of sunscreen. PPG-12/SMDI copolymer is a film-forming agent that has water binding properties and gives a smooth feeling to the skin. The last ingredients are grapefruit peel oil, limolene, citral and linalool. These last ingredients are generally used as aroma compounds from plants to provide fragrance – the grapefruit peel oil, limolene and citral give a citrusy scent, and linalool comes from many different plants and provides a floral scent with a bit of spice. The box says fragrance-free, so I’m assuming this means no added chemical fragrances. These plant fragrances and oils can be irritating to the skin.

I used this in the morning after cleansing and toning and used one drop for my forehead, one drop for each cheek area and one drop for the chin and jawline. When I first used this product, I was surprised by how thin it is; a water-like consistency. This made it hard to see and feel if each drop was being spread over each area. After a few days of use, though, I got used to the consistency and found the drops were being spread around. When putting this on, it absorbed immediately and made the skin feel very silky upon application (due to the silicones). It smells great; like oranges (this fragrance, though natural, is probably not necessary). After applying the serum and waiting a few minutes I only used my Colorescience Sunforgettable powdered sunscreen on top because I wanted to see how my skin reacted to the vitamin C and how it performed on its own. I usually otherwise use YBF Balance in the morning to absorb the oil on my skin throughout the day.

By the end of the first week of use I thought my skin looked a little brighter; it was very subtle. At the end of week 2 I started to get breakouts; a couple on my forehead, four small ones between my eyebrows, and a big one on the right cheek. I get breakouts every couple months, but not so many at once, and they come and go. The left side of my lower cheek breaks out every couple months and lasts a long time, and has come and gone for a long time. I have two theories about the increased breakouts during this time. My skin could have been getting used to a new product or my already oily skin does not like the extra oil from this product. Because of this, I am going to add my YBF Balance back in the morning. This is a product that absorbs oil and prevents breakouts. This product doesn’t have an effect on fine lines or hyperpigmentation, so I should still be able to see a difference in my skin with the use of Medik8 CE-Tetra.

After this one month of the Medik8 CE-Tetra use I am not seeing any difference in my fine lines or hyperpigmentation yet. Some products take time to see results. I will continue use and update in another 2 months.

While the lighting and focus looks better, unfortunately, I’m not noticing a lot of difference after the 90 days of use – the hyperpigmentation has not faded noticeably (if at all). The fine lines on my forehead have also not diminished. I do notice that my skin does look overall brighter and feels much softer than it has in a long time. As I had noted at one months, I felt that my skin had more breakouts than usual. These have mostly calmed down other than the right side of my face where breakouts seem to occur every couple weeks to month. I’m beginning to think these are hormonal breakouts. The serum, specifically the jojoba oil, doesn’t seem to make my skin oilier than it usually is, which is something I was worried about.

Despite not noticing much difference in the fine lines and freckles while using this vitamin C serum, I am going to continue use; I still have about two-thirds of the bottle left and I think that vitamin C is very beneficial for the skin. Once I’m done the bottle I might try the vitamin C serum from Mad Hippie, it’s much less expensive and I feel like I should see more results by now from an expensive product such as this from Medik8 (of course expense doesn’t guarantee results). I am also tempted to try another vitamin C serum also from Medik8 called CE-Thione, a “step-up” from the CE-Tetra.
