facetheory Regena C20 20% Stabilized Vitamin C Serum
Facetheory Regena C20 20% Stabilized Vitamin C Serum is a high-potency treatment designed to brighten the complexion and defend against environmental stressors. Formulated with 20% Sodium Ascorbyl Phosphate, a stable and less irritating derivative of Vitamin C, this serum is particularly well-suited for those who find pure L-ascorbic acid too harsh. The inclusion of Liquorice Extract works synergistically to target hyperpigmentation and redness, while Dill Extract supports skin elasticity. Unlike many heavy serums, the Regena C20 features a lightweight, hydrating base of Aqua and Olive-derived Squalane. Squalane provides essential moisture without a greasy finish, mimicking the skin's natural oils to keep the moisture barrier intact. The texture is smooth and absorbs quickly, making it an excellent addition to a morning skincare routine under sunscreen. For those seeking to even out skin tone, reduce the appearance of fine lines, and achieve a healthy glow without the risk of rapid oxidation common in other Vitamin C products, this facetheory serum offers a balanced, effective solution.
Our Analysis
Our analysis of the facetheory Regena C20 Serum reveals a low comedogenic risk overall, making it a strong candidate for most skin types. The only flagged ingredient is Tocopherol (pure Vitamin E), which carries a comedogenic rating of 2 out of 5. While thick Vitamin E oil can be potentially pore-clogging for some in its pure form, it is used here as an antioxidant stabilizer. Notably, the formula uses Sodium Ascorbyl Phosphate, a form of Vitamin C that is known to be gentle and beneficial for acne-prone skin, alongside non-comedogenic Squalane.
Skin Type Recommendations
This serum is excellent for all skin types, including sensitive and acne-prone skin, thanks to the stable form of Vitamin C. Oily and combination skins will appreciate the lightweight Squalane base, while those with hyperpigmentation will benefit from the brightening liquorice extract. It is generally safe for acne-prone users.
Flagged Ingredients
Pure Vitamin E is thick and sticky; safe in small amounts as an antioxidant, but potentially clogging in pure oil form.
