Medik8 Daily Radiance Vitamin C

For everyday wear, yes: it is a broad-spectrum SPF 30 protecting against UVA and UVB, provided you apply a liberal amount and reapply through the day as Medik8 directs. For long days outdoors, holidays or sport, Becci suggests a dedicated SPF 50+ such as Advanced Day Ultimate Protect, reapplied at least every two hours.

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.

Both contain stabilised vitamin C in a silky day cream for antioxidant power and radiance. Medik8's distinction is simple: Daily Radiance Vitamin C also delivers broad-spectrum SPF 30, so it is the final step of your morning, while C-Tetra Cream needs a separate sunscreen on top.

Yes - Medik8 describes its smoothing, radiance-boosting finish as the ideal glowy base for make-up. Apply a liberal amount, let it settle for a few minutes, then apply make-up as usual.

Chemical. Medik8 describes the Advanced UV Filters as a complex of premium chemical sun filters chosen for performance, skin-friendly feel and stability in sunlight, which is why it has a light, cashmere-soft texture that melts into the skin.

Absolutely - Medik8 recommends using vitamin C and sunscreen every day alongside vitamin A in the evening as its CSA Philosophy. Daily Radiance Vitamin C covers the morning C and S; Crystal Retinal is the evening A.

Not necessarily. Daily Radiance Vitamin C carries the same 7% stabilised vitamin C as the original C-Tetra serum, so for most people it is the vitamin C step. If you want a higher dose, apply C-Tetra Luxe or Super C Ferulic first and Daily Radiance Vitamin C on top as your moisturiser and SPF.

Medik8 says to blend a liberal amount across the face, neck and décolletage - sun protection depends on using enough - and counts around 90 uses per 50ml jar, so roughly three months of mornings.

It contains no vitamin A, which is the ingredient most people are asked to avoid. Medik8 does not publish formal pregnancy or breastfeeding guidance: as a cosmetics company it says it cannot advise on medical conditions and asks customers to discuss the full ingredient list with their midwife or GP before use. Its only general note is that the formula contains no ingredients it would recommend avoiding in pregnancy unless your doctor advises otherwise. Please check with your midwife or GP first.
