The Ordinary Ethylated Ascorbic Acid 15% Solution
The Ordinary Ethylated Ascorbic Acid 15% Solution is a highly stable, water-free serum designed to brighten skin tone and provide potent antioxidant protection. Unlike traditional Vitamin C (L-Ascorbic Acid) which can be unstable and irritating, this formula uses an ethylated derivative that acts directly like Vitamin C for faster results. The inclusion of Propanediol as a base gives the solution a lightweight, slightly oily feel upon application, though it absorbs quickly without leaving a heavy residue. This minimalist formula focuses on delivering a high concentration of Vitamin C to target dullness, uneven texture, and signs of aging. Because it is water-free, it remains stable for longer, ensuring you get the full benefits of the antioxidant with every drop. For those struggling with post-acne marks or hyperpigmentation, this solution offers a targeted approach without the common irritants found in many brightening serums. It is a straightforward, effective addition to any preventative or corrective skincare routine, providing the radiance-boosting benefits of Vitamin C in a format that is gentle enough for consistent daily use.
Our Analysis
Our analysis of The Ordinary Ethylated Ascorbic Acid 15% Solution reveals a Low comedogenic risk level. We found zero flagged ingredients in this minimalist formulation. The primary base is Propanediol, which serves as an effective solvent and humectant that is generally considered non-comedogenic and safe for those with congestion-prone skin.

Skin Type Recommendations
This product is ideal for oily, combination, and acne-prone skin due to its non-comedogenic profile. Dry skin types will appreciate the humectant properties of Propanediol.
