Your Glow-Up in a Bottle — Why RADIANT•K is the Vitamin C Oil That Actually Works

by Tina

The secret to glowing, even-toned skin—without irritation or empty promises.

 

 

If you’ve ever slathered on a Vitamin C serum only to wonder, “Is this even doing anything?”—you’re not alone. Most vitamin C products on the market fall flat. They're either unstable, watered down, too irritating, or they oxidize before you even hit the halfway mark.

Enter RADIANT•K, your new skincare obsession from the glow pros at TINA•K. This isn't your average citrusy vitamin c oil—it’s a power-packed, highly concentrated oil-based treatment that goes deep into the skin to get serious about brightening, tightening, and protecting your barrier.

Let’s Get Nerdy 🤓: The Type of Vitamin C Matters, Trust Us

So what sets RADIANT•K apart? It’s all about the form of Vitamin C used. Instead of the most common (and commonly unstable) L-ascorbic acid, RADIANT•K uses Tetrahexyldecyl Ascorbate—a potent, oil-soluble derivative that penetrates more deeply and remains stable longer, all while being gentle on even the most sensitive skin types.

This means:

  • It doesn’t oxidize quickly like other Vitamin C products

  • It actually absorbs into your skin, instead of just sitting on top

  • It boosts collagen production at a deeper level

  • It fades discoloration and brightens with long-term, visible results

  • And it does all of this without stinging or sensitizing your skin

It’s like a turbocharged glow oil that doesn’t flake on you.

 

 

A Concentrated Formula That Works (No Fillers Here)

You’ll find no fluff in RADIANT•K. This luxurious facial oil is concentrated, meaning it delivers maximum active benefits in just a few drops. It’s suspended in a nourishing oil base that supports your skin barrier, softens texture, and locks in moisture—all while the Vitamin C does the heavy lifting.

This is skincare that multitasks:

  • Brightens and evens tone

  • Reduces the appearance of dark spots and hyperpigmentation

  • Strengthens and smooths the skin’s surface

  • Defends against environmental stressors like pollution and UV damage

  • Hydrates and softens without clogging pores

Whether you’re dealing with dullness, discoloration, or simply want a gorgeous, lit-from-within glow, RADIANT•K was formulated to actually deliver.

How to Use RADIANT•K

RADIANT•K is designed to be simple, effective, and easy to slip into your existing routine. Here’s how to make it work for you:

  1. Cleanse skin with a gentle cleanser like YOGURT•K (for hydration) or PERFECT•K (for deep pore detox)

  2. While skin is still slightly damp, apply ¼ pipette of RADIANT•K to your face, neck, and décolleté

  3. Follow with a moisture-locking cream like EMOLLIENT•K for added plump

  4. Use morning and night, or just in the morning for antioxidant protection throughout the day

Makeup wears beautifully over it. Dry skin drinks it in. Oily skin? Don’t worry—it balances that too.

 

 

Who is This For?

Everyone. That’s the beauty of RADIANT•K. If you’re looking to:

  • Fade dark spots or sun damage

  • Brighten dull, uneven tone

  • Hydrate without heaviness

  • Protect your skin from free radicals

  • Level-up your glow game

Then this oil is your new best friend.
