- brightens dull skin
- reduces surface inflammation and puffiness
- helps skin defend itself from external stressors like pollution
- improves skin hydration
- offers acne benefits (certain types of vitamin C only)
It's a bit of a skin superstar! Today I'm sharing four affordable products that I've been testing out over the last several months.
Today's lineup feature three different forms of vitamin C:
L-Ascorbic Acid: the most researched form of vitamin C. Proven to be effective, but can cause surface skin irritation. It also has stability issues and can oxidize both in water formulas and on the skin.
Sodium Ascorbyl Phosphate: a stable water-soluble form of vitamin C that converts to ascorbic acid after absorption. SAP is gentler and does not cause the same irritation as ascorbic acid, and has also been researched and shown to have acne benefits.
Tetrahexyldecyl Ascorbate: a stable fat-soluble form of vitamin C. Because it's lipid-soluble, tetrahyxyldecyl ascorbate is able to penetrate deeper into the skin's dermis, where it can have more of an effect on collagen production.
