The Story ✨

RADIANT•K Power C Oil

THE STORY 

Not all Vitamin C is created equal—and at Tina K, we don’t do reactive, inconsistent, or unpredictable.

Traditional Vitamin C can be harsh. It oxidizes quickly, loses potency, and for many, it triggers sensitivity and irritation. That’s not luxury skincare—that’s guesswork.

So we upgraded it.

RADIANT•K Power C Oil was intentionally formulated with Tetrahexyldecyl Ascorbate (THD Vitamin C)—a next-generation, oil-soluble form of Vitamin C that is exceptionally stable, highly effective, and beautifully tolerated by the skin.

No stinging. No drama. Just results.

We paired this powerhouse with a base of pure squalane—chosen not just for hydration, but for its ability to mimic your skin’s natural lipids, allowing for deeper penetration and enhanced delivery of active ingredients.

This is where performance meets precision.

• Brighten without irritation

• Smooth without heaviness

• Strengthen without compromise

RADIANT•K works below the surface to stimulate collagen, suppress excess melanin, and visibly refine skin texture, while wrapping your skin in a breathable, nourishing layer that locks in hydration and defends against environmental stress.

Think of it as your daily glow checklist —correcting, protecting, and elevating your skin in one effortless step.

The result? Skin that looks clearer, stronger, more even, and undeniably radiant.

Upgrade your Vitamin C. Upgrade your skin.

Tap into RADIANT•K and give your skin the glow it actually deserves.

    FAQs

    Are your products organic / natural?

    Our Ingredient Philosophy

    Tina K skincare, body care, and bath products are thoughtfully formulated with a balance of organic botanicals and advanced scientific ingredients. We believe truly corrective skincare happens when nature and science work together in perfect synergy.

    Botanical ingredients support the skin with nourishment and wellness, while clinically studied actives deliver the efficacy and corrective results your skin needs.

    Our philosophy is simple: care deeply about health and wellness, while remaining uncompromisingly results-driven. Each formula is intentionally crafted so every ingredient works together to support stronger, healthier, more radiant skin. ✨

    Do your products contain fragrance?

    At Tina K, fragrance is intentional. Our products are either lightly kissed with the cleanest fragrance available or completely fragrance-free—giving your skin exactly what it needs, nothing it doesn’t. We do not use any Prop 65–listed fragrances, and every formula is designed to feel fresh, natural, and effortlessly clean. From body oils to skincare, you’ll always have the option to go scent-free or subtly scented—never overwhelming, always elevated.

    Is there talc in any of your products?

    Talc-Free Commitment

    All Tina K products are 100% talc-free. We believe beauty should support both health and wellness, which is why our formulas are thoughtfully created without talc.

    Our approach is simple: keep your beauty routine clean, conscious, and skin-supportive so you can enjoy products that feel as good for your health as they do for your skin.

    What is the shelf life of my product?

    All Tina K skincare products have a 12-month shelf life after opening, also known as the Period After Opening (PAO). This standard applies across our entire skincare system.

    After 12 months, the formula may still be enjoyable to use, but the potency and efficacy of the active ingredients can begin to decline. For best results and optimal performance, we recommend using your product within this one-year window after opening.
