If you've ever tried a vitamin C serum and experienced irritation, or watched it turn yellow and wondered whether it was still working, you've probably realized that not all vitamin C is created equal. That's why Mimar's Ultra Vit C Concentrate uses 15% THD Ascorbate, a stable, oil-soluble form of vitamin C designed to brighten dull skin, improve the appearance of dark spots, and support collagen production, without the harshness often associated with traditional vitamin C serums. Powerful results, without the unnecessary irritation.

When Your Vitamin C Serum Goes Bad Before You Finish It

You invest in a vitamin C serum for brighter, healthier-looking skin, only to watch it turn yellow, orange, or brown before you’ve even finished the bottle. That colour change can be a sign of oxidation, a process that occurs when vitamin C is exposed to oxygen, light, and heat. And suddenly, the serum you carefully chose to improve your skin might not be delivering the same benefits it did when you first opened it.

The frustrating part? Oxidation can happen while you're still working your way through the bottle. Many traditional vitamin C serums use L-ascorbic acid, a form of vitamin C that can be particularly prone to instability. Once oxidation occurs, its effectiveness will decline, meaning you're paying for an ingredient that isn't performing as intended. That half-full bottle sitting on your bathroom shelf? It may not be giving your skin the benefits you expected and you lose trust in vitamin C serums.

Why Ultra Vit C Concentrate is better

Mimar's Ultra Vit C Concentrate uses 15% THD Ascorbate, a stable, oil-soluble form of vitamin C designed to resist oxidation better than traditional L-ascorbic acid. The result is a more stable approach to daily brightening and skin support, so you can focus on your skincare results instead of racing against the clock to finish your bottle.

It doesn't cause skin sensitivity because there is no pH to begin with (pH is only associated with water-based products).

Our Vitamin C is blended with a mix of botanical oils and extracts to further support skin concerns like dark spots, dull skin, loss of elasticity in the skin and scented with organic essential oils. Ultra Vit C Concentrate is 100% natural and clinically proven. Ultra Vit C Concentrate, supports the skin barrier to thrive and does not use any hormone disruptors in the formula. Mimar's Ultra Vit C Concentrate is formulated an effective and easy to use vitamin C serum for daily use, that is safe to use during pregnancy, breastfeeding. 

Switch to a non-toxic, zero reaction Vitamin C Serum

The beauty industry would have you believe that all vitamin C serums are created equal. They’re not. The type of vitamin C, the formula, and the ingredients behind the label all matter. And just because a bottle says natural doesn’t mean the ingredients list tells the same story.

That's why Mimar's Ultra Vit C Concentrate is genuinely good for you, we believe you shouldn’t need a chemistry degree to understand your skincare. No fine print to decode. No fillers or synthetic fragrances quietly making their way into your routine. Just a thoughtfully crafted, 100% natural formula designed to deliver results without unnecessary ingredients or compromising your skin’s comfort.

Because effective skincare shouldn’t come at the expense of what you put on your body. Know what’s in your skincare. Know what it’s doing. Expect more from your vitamin C.
