Daily defence for brighter skin

Vitamin C is a powerhouse antioxidant that helps defend the skin against free radicals caused by UV exposure and environmental factors. With consistent use, it aids collagen production and works to visibly reduce dullness, fine lines and uneven tone. Applied in the morning after cleansing, vitamin C prepares your skin for the day ahead, absorbing quickly and layering well under moisturiser and sunscreen.

Frequently Asked Questions

What does vitamin C do in skincare?

Vitamin C is a powerful antioxidant that helps to brighten skin tone, even out pigmentation and boost collagen production. It also defends against environmental damage, such as pollution and UV exposure, for visibly smoother, more radiant skin.

For daily use, we recommend our  Daily Radiance Vitamin C moisturiser, which combines vitamin C with SPF 30, making it a simple and effective morning step alongside your evening vitamin A routine.

How to use vitamin C in skincare?

Apply vitamin C in the morning after cleansing and before moisturiser or sunscreen in your skincare routine. It works best on clean, dry skin and should be used consistently for visible results. Pairing it with daily SPF helps protect against environmental damage and supports a brighter, more even complexion.

Medik8’s C-Tetra Cream is the perfect starting point for anyone new to vitamin C. It helps restore radiance while defending against the visible signs of ageing caused by environmental stressors.

How long does it take to see results from vitamin C?
With consistent daily use, you may begin to notice a brighter, more even skin tone within 2 to 4 weeks. Improvements in overall radiance, texture and clarity become more visible over time, especially with continued use. Long-term benefits, such as reduced appearance of pigmentation and fine lines, typically develop over 8 to 12 weeks.

Is vitamin C suitable for all skin types?

Yes, vitamin C can be used by all skin types, including sensitive skin. The key is choosing the right strength and format for your skin’s needs. Stabilised forms of vitamin C, like tetrahexyldecyl ascorbate found in Medik8’s C-Tetra range, offer powerful brightening benefits in a gentle, non-irritating formula, ideal for daily use, even on delicate or reactive skin.

Does vitamin C help with blemish-prone skin?

Vitamin C can support blemish and acne-prone skin by calming inflammation, fading post-blemish marks and strengthening the skin barrier. Its antioxidant properties also help to reduce oxidative stress, which can contribute to breakouts.

A gentle vitamin C serum, like C-Tetra Advanced, is ideal for breakouts, delivering glow-boosting benefits without clogging pores.

Can you use vitamin C with retinol?

Vitamin C and vitamin A work best when used at different times of day: apply vitamin C in the morning for daily antioxidant protection, then use vitamin A (retinol) in the evening to support renewal. Used this way, they deliver complementary results while staying true to the CSA approach.
