5 Reasons Women Over 50 Are Switching to This Vitamin C (and Not Looking Back)

After 50, skin gets drier, thinner and more sensitive. The vitamin C serum that used to work can start to sting, sit on top of your skin, or do nothing at all. Here's why a stable, oil-soluble 15% concentrate is different.

1. Gentle, But Strong Enough for Real Results

Gentle shouldn't mean weak. Our serum has 15% THA, a clinically studied form of vitamin C that supports your skin's own collagen for firmer, smoother-looking skin. In our clinical study, 86% of women saw plumper skin within 4 weeks.

2. No More Dry, Tight Skin

After menopause, skin makes less of its own oil, so water-based serums can leave it feeling tight and thirsty. Ours is waterless, with 15% vitamin C in a nourishing base of sea buckthorn, açaí and jojoba oils that replace the moisture mature skin is missing, so it feels soft and comfortable all day.

3. It Won't Sting or Leave You Red

Many women find their old vitamin C starts to sting after 50. That's because most vitamin C serums need a harsh, acidic pH to work, and mature skin is thinner and more sensitive. Ours uses THA, an oil-soluble vitamin C that needs no low pH, so you get the results without the burn or redness.

4. No Sticky Film, No Pilling Under Makeup

Many vitamin C serums leave a tacky layer that balls up under foundation. Ours is a light oil that sinks in quickly and leaves skin soft, not sticky, so your makeup glides on smoothly on top.

5. It Won't Turn Orange Halfway Through

Water-based vitamin C breaks down every time you open the bottle, which is why so many turn orange before you finish them. Ours is waterless and built on stable THA, so it stays fresh and potent from the first drop to the last. No fridge needed.

From our founder

In my 40s, I wanted one daily product that was clinically effective, naturally formulated and gentle enough to use every day. All I could find were harsh clinical serums or gentle naturals that didn't really work. So I stopped looking and started building.

I started researching while on maternity leave with my first daughter, during those late-night feedings, and worked alongside cosmetic chemists and aestheticians. Over four years I tested more than 80 formulations, sourcing botanicals from across Canada and the U.S.

The breakthrough was Tetrahexyldecyl Ascorbate, an oil-soluble vitamin C that stays stable, never oxidizes and absorbs without stinging. I built the entire formula around it and used it at 15% in a nourishing botanical oil base with organic frankincense and rose geranium. No water, no petroleum fillers, no synthetic fragrance.

In 2022, a retailer tried my sample on the hyperpigmentation above her lip and was shocked by the results. Aestheticians started using it in their facials, and that's how Ultra Vit C Concentrate was born. Today over 20,000 women use it, and I hope you love it as much as I do.
