Mary&May Idebenone + Blackberry Complex Serum
Skin-Nomad's Take — At a Glance
- 1,000 ppm Idebenone with a 20% Blackberry Complex
- Stable in light, so it works in a morning routine
- Fast-absorbing, and orange because of the active itself
Antioxidant serums usually mean Vitamin C, which brings instability and irritation along with the benefits. Mary&May uses Idebenone instead, a synthetic relative of CoQ10, at 1,000 ppm alongside a 20% Blackberry Complex of anthocyanin-rich extracts. The Seoul brand treats concentration as the difference between a formula that works and an ingredient list that reads well.
Key Benefits
- Idebenone neutralises free radicals at 1,000 ppm. Comparative laboratory work has ranked it favourably against Vitamin C, Vitamin E, CoQ10, and alpha-lipoic acid on antioxidant capacity, though that research is limited in volume and mostly not head-to-head on finished products. At this concentration it is doing real work rather than appearing on the label.
- It supports collagen-producing cells as well as protecting. Alongside the antioxidant activity, Idebenone has documented effects on cellular energy production and collagen activity, which is what makes it a skin longevity ingredient rather than a purely defensive one.
- A 20% Blackberry Complex covers different pathways. Blackberry, Acai, and Blueberry extracts bring anthocyanins and polyphenols that work through different antioxidant routes than Idebenone, so the two broaden the coverage rather than doubling it.
- It stays stable in daylight. Unlike L-Ascorbic Acid, Idebenone does not oxidise on exposure to light and air, so it holds its potency through the day and across the life of the bottle.
Texture & Finish
A fast-absorbing fluid, distinctly orange in the bottle from the Idebenone itself rather than any added colour, drying down clear with no tack. It sits cleanly under sunscreen.
Ideal For
- Skin types: All skin types, including skin that reacts to Vitamin C.
- Skin concerns: Environmental and pollution exposure, loss of firmness, dullness, and uneven tone.
- Best used by: People who want a morning antioxidant that will not oxidise in the bottle, and anyone whose skin has ruled Vitamin C out.
FAQ
Q: How does Idebenone compare to Vitamin C?
A: They do overlapping work by different routes. Vitamin C is antioxidant and brightening, extremely well researched, and unstable. Idebenone is antioxidant-led with some collagen activity, stable in light and air, and better tolerated, but its research base is much smaller and largely laboratory rather than clinical. If brightening is your goal, Vitamin C remains the better-evidenced choice; if stability and tolerance are the problem, Idebenone is the practical one.
Q: Why is the serum orange?
A: That is the Idebenone. The colour comes from the active itself rather than a dye, and it fades as the product oxidises slowly over its life, which makes it a rough visual indicator of freshness.
Q: Morning or evening?
A: Morning gets more from it. Antioxidants work best where the oxidative stress is, which is daytime UV and pollution exposure, and unlike Vitamin C this one has no stability reason to avoid daylight.
The most useful thing about a stable antioxidant is not its potency on paper. It is that the last application is as strong as the first.
