About "Vitamin C Day"
The skin is constantly exposed to oxidative stress from external factors such as UV rays and air pollution, as well as internal factors like stress and lifestyle habits. When oxidative stress increases, reactive oxygen species are generated in the body, causing various signs of aging such as wrinkles, dark spots, loss of firmness, dullness, and uneven skin tone. Vitamin C is an essential antioxidant ingredient that protects the skin from damage caused by such reactive oxygen species.
Dr. Pinnell, the founder and scientist of SkinCeuticals, laid the foundation for Vitamin C research in skincare through over 40 years of pioneering research on Vitamin C's penetration, stability, and antioxidant function. "National Vitamin C Day" was established on April 4, 2019, to commemorate this research and the scientific efficacy of Vitamin C.
The History of SkinCeuticals' Antioxidant Research
1990s: Discovery of Vitamin C's Efficacy in Skincare
In 1997, Dr. Pinnell and his colleagues discovered that topical Vitamin C (applying Vitamin C to the skin) inhibits UV-induced redness and the generation of sunburned cells*6. This led to the proposal of a new skincare concept: photoprotection through antioxidants, distinct from sunscreen. In 1997, the first SkinCeuticals skincare formulation using Vitamin C was developed.
2000s: Establishment of the Golden Standard for Vitamin C Penetration
In 2001, the "Golden Standard" was established, defining the key conditions (Vitamin C type, pH, concentration) crucial for Vitamin C's penetration into the skin, a long-standing challenge*7. Furthermore, in 2005, it was discovered that adding Vitamin E and Ferulic Acid to Vitamin C yielded approximately 8 times the photoprotective effect*8.
2010s to Present: Evolution into Research on the Relationship Between Vitamin C and Aesthetic Procedures
To this day, research continues on how formulations containing Vitamin C, Vitamin E, and Ferulic Acid affect the skin after aesthetic procedures.
