Medik8 C tetra Reviews

Developed by Medik8, a renowned skincare brand known for its innovative and effective formulations, C Tetra is designed to provide targeted antioxidant protection and brightening benefits.

What are our top skincare picks?

Who is it for?

C Tetra is suitable for individuals of all skin types who are looking to enhance their skincare routine with the benefits of vitamin C. Whether you have dry, oily, or combination skin, this product can be incorporated into your daily regimen to address various skin concerns, including dullness, uneven skin tone, and signs of aging.

What are the key ingredients?

The key ingredient in Medik8 C Tetra is tetrahexyldecyl ascorbate, a stable and oil-soluble form of vitamin C. This form of vitamin C is highly effective in penetrating the skin and delivering its potent antioxidant properties. It helps to neutralize free radicals, which are unstable molecules that can cause damage to the skin cells and accelerate the aging process.

In addition to tetrahexyldecyl ascorbate, C Tetra also contains tocopherol acetate, a form of vitamin E that works synergistically with vitamin C to enhance its antioxidant activity. Vitamin E also provides nourishment and hydration to the skin, helping to improve its overall health and appearance.

What are the best anti aging skincare ingredients?

Vitamin C

We’ve been hearing for years that Vitamin C is the best anti-aging ingredient. Vitamin C is a potent antioxidant that protects the skin from free radicals, the unstable molecules that contribute to the formation of premature wrinkles and fine lines on the skin.

Vitamin C also helps fade dark spots, evens out skin tone, and increases radiance. As if that wasn’t enough, research suggests that when vitamin C is applied to the skin, it significantly reverses aging-related structural changes by influencing collagen and elastin synthesis.

But our favorite Vitamin C serum is Carrot & Stick The Defence Serum. It contains 3 distinct types of Vitamin C that work together to help fight free radical damage. We recommend using it every morning.


As you age, your body’s production of collagen and elastin slows down. These two proteins are responsible for your skin’s structural support. As a result, the skin loses its natural plumpness and smoothness.

While collagen is necessary for maintaining youthful-looking skin, the collagen protein is too large to absorb into the skin topically. That’s why applying skin care products that contain collagen won’t provide the anti-aging benefits you’re looking for.

This is where peptides come into action. Peptides are the building blocks of protein, and they are easily absorbed into the deeper layers of skin due to their smaller size.

If you’re looking for a peptide serum, recommend Carrot & Stick The Repair Serum. It contains 7 plant-based peptides to promote plumper and smoother-looking skin. It also has skin-loving ingredients like hyaluronic acid and niacinamide.


Retinol is the go-to anti-aging ingredient recommended by dermatologists and skin experts. Retinol is clinically proven to minimize the appearance of fine lines and wrinkles, improve uneven skin tone, restore skin firmness, and shrink the appearance of enlarged pores.

The only downside? Retinol can often lead to side effects like skin dryness, peeling, and irritation. Look for products that contain Hydroxypinacolone Retinoate, an ingredient that provides the same benefits of retinol but without the irritation. One that we recommend is this retinoid oil serum.

What is the texture like?

Medik8 C Tetra has a lightweight and non-greasy texture, making it easy to incorporate into your skincare routine. The serum-like consistency allows for quick absorption into the skin, leaving behind a smooth and velvety finish. It can be used both in the morning and evening after cleansing and toning, and before applying moisturizer and sunscreen.

What is the return policy?

Medik8 offers a comprehensive return policy for its products, including C Tetra. If you are not completely satisfied with your purchase, you can return the product within 30 days of receipt for a full refund. The product must be returned in its original packaging and in a resalable condition. For more information on the return process, you can visit the Medik8 website or contact their customer service team.


Consumer reviews of Medik8 C Tetra have been overwhelmingly positive, with Users reporting noticeable improvements in their skin’s texture and tone. One reviewer mentioned that the product helped fade their acne scars and brightened their complexion, while another praised its ability to reduce the appearance of fine lines and wrinkles.

Users also appreciated the lightweight and non-greasy texture of the product, as it allowed for easy absorption and layering with other skincare products. Some individuals with sensitive skin noted that C Tetra did not cause any irritation or redness, making it suitable for those with delicate skin.

Overall, consumers found Medik8 C Tetra to be an effective and reliable vitamin C serum that delivered on its promises. The product’s high concentration of vitamin C, combined with its stable formulation, ensured optimal results without compromising the skin’s integrity.

In conclusion, Medik8 C Tetra is a scientifically advanced skincare product that harnesses the power of vitamin C to improve the appearance and health of the skin. With its potent antioxidant properties and lightweight texture, it is suitable for individuals of all skin types. Incorporating C Tetra into your skincare routine can help address various skin concerns, while providing nourishment and protection for a radiant and youthful complexion.
