Mary&May Idebenone 1000ppm + Blackberry 20% Antioxidant Face Serum is a leave-on treatment designed to address signs of aging such as fine lines and loss of radiance. The formula combines 1000ppm of idebenone, a potent antioxidant often considered a gentle alternative to vitamin C, with 20% blackberry extract to provide additional antioxidant support. This serum is intended for those seeking a non-irritating brightening option, particularly for skin that may not tolerate higher concentrations of L-ascorbic acid. The product is EWG Verified, meaning its ingredients meet criteria for transparency and low hazard potential based on current scientific data. It has a lightweight, fast-absorbing texture that does not leave a sticky or tacky residue, making it suitable for layering under moisturizers or sunscreen. The serum is fragrance-free, which reduces the likelihood of olfactory irritation for sensitive users. Its primary functional claims focus on environmental oxidative stress reduction and support for a more even, brighter skin tone over continued use. The formulation does not contain added synthetic fragrances, dyes, or essential oils, and is free from common irritants such as alcohol and parabens. This serum comes in a 1.01 fl oz dropper bottle. It is appropriate for daily use, typically applied after cleansing and before moisturizing, both in the morning and evening routine. The concentration of idebenone at 1000ppm is a moderate level intended for regular antioxidant defense without the potential sting or yellowing sometimes associated with high-concentration vitamin C serums. The blackberry extract contributes a natural source of anthocyanins and vitamins to further neutralize free radicals. While the product is positioned as a gentle alternative, individual results may vary depending on skin condition, consistency of use, and overall skincare regimen. It is advisable to perform a patch test before full application, especially for those with reactive or allergy-prone skin. The serum is non-comedogenic and can be incorporated into most skincare routines without causing congestion.
