What should you know about Inkey List vitamin C EGF?

Vitamin C is used topically for antioxidant support and to help the appearance of uneven tone. EGF refers to epidermal growth factor, a signalling protein used in some cosmetic formulas; the term does not by itself prove that a product will repair skin or replace medical treatment. Formula strength, stability, packaging, and the rest of the ingredients influence tolerance. See the general [Vitamin C Serum](/materials/vitamin-c-serum/) guide for ingredient context.

Read the current label, patch-test as directed, and introduce the product on clean, dry skin without applying it to broken or inflamed areas. Use moisturiser when needed and wear broad-spectrum sunscreen during the day. Keep the routine simple at first so you can identify the cause of irritation. Stop combining it with several potentially irritating actives until your skin has shown it can tolerate the product.

Stop use and obtain advice if you develop persistent stinging, swelling, hives, blistering, or a spreading rash. Seek urgent help if facial swelling affects breathing. A dermatologist should assess a new or changing pigmented lesion, persistent inflammation, or a concern that does not improve with gentle care; cosmetic serum should not delay diagnosis.

Ask which vitamin C form is in the formula, whether it fits your skin condition, how to combine it with prescribed products, and what reaction should prompt immediate discontinuation.
