ALASTIN Brings Its C-Radical Defense Serum to the UK: Liposomal Sodium Ascorbate and 14 Antioxidants

ALASTIN, the professional skincare brand owned by Galderma, has launched its C-Radical Defense Antioxidant Serum in the UK, according to a report in Aesthetics Journal on 25 May 2026. The brand's UK site says its products are sold through selected physicians' offices, so this is a clinic product rather than one sold in ordinary shops.

The vitamin C in this serum is not L-ascorbic acid, the form used in many classic vitamin C serums. ALASTIN uses sodium ascorbate, a salt of ascorbic acid, enclosed in what it calls a proprietary liposomal delivery system. The brand presents this as a more stable approach. It does not publish a vitamin C percentage, so the strength cannot be compared with serums that state one.

Alongside vitamin C, the company describes a complex of 14 antioxidants, naming lactoferrin, ergothioneine, green tea extract, ectoin and coenzyme Q10. Its pitch is broad protection against UV, pollution and other everyday stressors, and it says the formula may help neutralise free radicals while conserving elastin. The report attributes that to laboratory work cited by ALASTIN, and no study, sample size or journal was named.

Two practical points for readers here. First, encapsulation is a formulation choice, and how much vitamin C actually reaches the skin depends on the full product. A small 2026 membrane test sponsored by another brand found an encapsulated sodium ascorbate product absorbed no better than a plain 15% L-ascorbic acid serum after 72 hours, although that test did not name the products. Second, we found no Indian listing for this serum, so it is not part of our price comparisons.
