✓ 30% Ethylated L-Ascorbic Acid | ✓ Medik8's Most Powerful Vitamin C | ✓ Clinically Shown: Fewer Wrinkles in 4 Weeks

Medik8 Super C Ferulic is the serum Medik8 calls its most powerful vitamin C: 30% ethylated L-ascorbic acid with ferulic acid, vitamin E and turmeric root extract, clinically shown to visibly reduce wrinkles, dark spots and uneven tone while improving skin firmness. Designed to work on all skin tones, it is the high-strength vitamin C serum for mature skin showing advanced signs of sun-induced ageing.

The vitamin C in Medik8 Super C Ferulic is 3-O-ethyl ascorbic acid, a stabilised derivative Medik8 says delivers powerful visible brightening, wrinkle-reducing and antioxidant benefits, and is so stable that the serum stays effective until the last drop. Ferulic acid is a supercharged antioxidant that boosts the power of vitamins C and E, vitamin E works in synergy with it to nourish and protect, and turmeric root extract helps reduce the look of age spots and discolouration. In Medik8's independent 12-week clinical study on 32 participants of all skin types and tones, wrinkles were visibly reduced and firmness increased within 4 weeks, and 93% agreed it worked faster than any vitamin C they had tried; a separate 7-day consumer study (41 participants) found a brighter, more even complexion.

Choose Medik8 Super C Ferulic if your skin is used to actives and you want the strongest vitamin C in the Medik8 range; if your skin is sensitive, start with C-Tetra instead.

Becci has spent more than two decades as a registered aesthetics nurse in specialist skincare and medical aesthetics, and she is as quick to say 'not this one' as 'yes'. Medik8 Super C Ferulic is a serum she recommends selectively: for robust, experienced skin with stubborn dark spots it is the strongest vitamin C she stocks; for sensitive skin she steers clients to C-Tetra instead. That honesty is why they ask her first.

FAQS

Is Medik8 Super C Ferulic the strongest vitamin C serum Medik8 makes? +

Yes - Medik8 calls it its most powerful vitamin C serum. It contains 30% ethylated L-ascorbic acid, above C-Tetra Advanced at 20%, C-Tetra Luxe at 14% and C-Tetra at 7%, and it is the only one of the four built on an ethylated form of vitamin C rather than tetrahexyldecyl ascorbate.

What is the difference between C-Tetra, C-Tetra Luxe and C-Tetra Advanced? +

All three use the same gentle, stabilised vitamin C (tetrahexyldecyl ascorbate); they differ in strength and texture. C-Tetra is the original: 7% in a lightweight oil, for sensitive skin and anyone new to vitamin C. C-Tetra Luxe doubles that to 14% in a rich, nourishing oil with squalane and maracuja oil, for all skin types, first signs of ageing and especially dry skin. C-Tetra Advanced is the newest and strongest of the three at 20%, in a lightweight gel-serum with phyto exosomes, for visible signs of ageing on normal, combination or oily skin. Above them sits Super C Ferulic, 30% ethylated L-ascorbic acid for advanced sun-induced ageing, and the technology also comes as C-Tetra Cream (3%) and Daily Radiance Vitamin C (7% with SPF 30) for anyone who prefers a cream.

Is Super C Ferulic suitable for sensitive skin? +

No. Medik8 says that because of its potency it is not recommended for sensitive skin types, and points sensitive skin to C-Tetra, which is shown to be gentle. If your skin is robust but you are new to strong actives, patch test and build up gradually.

Why does Super C Ferulic tingle when I apply it? +

Medik8 says a slight tingle on application is normal for a 30% vitamin C and it should settle within moments. If stinging persists or your skin reddens, it is likely too strong for you - stop, and step down to C-Tetra or C-Tetra Luxe.

Does Super C Ferulic work on darker skin tones? +

Yes. Medik8 says it is designed to work on all skin tones, and its 12-week clinical study was run on 32 participants of all skin types and tones. The turmeric root extract is included specifically for the look of dark spots and discolouration.

Can I use Medik8 Super C Ferulic with Crystal Retinal or retinol? +

Yes - Medik8 recommends vitamin C plus sunscreen in the morning and vitamin A at night as its CSA Philosophy. Keep Super C Ferulic to the morning and Crystal Retinal to the evening rather than layering two strong actives together.

Will Super C Ferulic go off or turn brown? +

It is far more stable than pure L-ascorbic acid serums. Medik8 says ethylated L-ascorbic acid is exceptionally stable and stays effective until the last drop, and gives a shelf life of 30 months unopened and 12 months from opening.

What did the clinical study on Super C Ferulic show? +

In Medik8's independent 12-week clinical study on 32 participants of all skin types and tones: visibly reduced wrinkles in 4 weeks, increased skin firmness and elasticity in 4 weeks, visibly reduced dark spots and age spots and a more even tone, with 93% agreeing it worked faster than any vitamin C they had tried. A 7-day consumer study on 41 participants found a brighter, more even complexion in a week.

Can I use Medik8 Super C Ferulic during pregnancy or while breastfeeding? +

It contains no vitamin A, which is the ingredient most people are asked to avoid. Medik8 does not publish formal pregnancy or breastfeeding guidance for this product: as a cosmetics company it says it cannot advise on medical conditions, and it asks customers to discuss the full ingredient list with their midwife or GP before use. Please check with your midwife or GP first.
