Medicube Deep Vita C Capsule Cream$29 / 55ml — $0.53/ml

Formulation Summary

A dual-texture brightening cream with golden vitamin capsules in a transparent gel. The base replaces water with 50% sea buckthorn water, a rich source of natural vitamin C and carotenoids. Five vitamin C derivatives plus niacinamide and alpha-arbutin address dark spots from multiple angles.

Medicube builds on the capsule cream concept, this time targeting brightening. Sea buckthorn water at 50% provides the base with natural vitamin C and omega fatty acids. Sodium Ascorbyl Phosphate offers a stable vitamin C derivative. The formula adds alpha-arbutin and niacinamide for layered melanin control. Ferulic acid and tocopherol boost vitamin C stability and antioxidant potency. The inclusion of B-vitamins (biotin, folic acid, riboflavin) is unusual and supports cellular metabolism.

The Formulation Explained

Sea buckthorn water base

Replacing purified water with 50% sea buckthorn water adds inherent vitamin C and carotenoids to the formula base. Sea buckthorn is rich in omega-7 fatty acids, which support skin repair. This approach is similar to EQQUALBERRY's acerola water base but uses a different botanical source.

Multi-vitamin approach

Beyond vitamin C derivatives, the formula includes B-vitamins like biotin, folic acid, thiamine, riboflavin, and pyridoxine. This B-vitamin complex supports cellular metabolism and energy production. While less common in topical skincare, these vitamins contribute to overall skin cell health.

Clinical results cited

Medicube reports skin radiance improvement of 34.8% immediately after application and 32.6% after 24 hours. Reduction in spots and roughness observed after four weeks. Irritation index tested at 0.00%. Full methodology is not publicly available.
