Vitamin C is one of the most beloved ingredients in skincare—but not all forms deliver the same results. Traditional vitamin C (L-ascorbic acid) can be unstable, irritating, and too harsh for mature, sensitive, or dry skin. That’s why Shea Radiance selected Tetrahexyldecyl Ascorbate (THD Ascorbate): a next-generation, oil-soluble vitamin C that offers powerful brightening and radiance-enhancing benefits while respecting the skin barrier.
THD Ascorbate is the hero ingredient in our Vitamin C Face Oil, formulated to deliver glow, clarity, and comfort—aligned with our pro-aging philosophy of nourishing the skin, not fighting it.
What Makes THD Vitamin C So Special?
1. Oil-Soluble for Deep Penetration
Unlike water-soluble vitamin C, THD dissolves into the skin’s natural lipids. This gives it the ability to reach deeper layers of the skin where tone, texture, and firmness improve.
Deep delivery means better support for:
- Skin clarity
- Visible firmness
- Radiance
- Overall glow
Its ability to absorb deeply makes it ideal for mature or dehydrated skin.
2. Gentle and Non-Irritating
Many vitamin C serums sting or cause redness—especially on barrier-compromised or sensitive skin. THD Ascorbate is uniquely gentle, making it suitable for:
- Mature skin
- Dry or dehydrated skin
- Sensitive or easily irritated skin
- Melanin-rich skin that reacts to harsh acids
It brightens without triggering inflammation.
3. Highly Stable and Long-Lasting
Traditional vitamin C oxidizes quickly, losing potency. THD Ascorbate is remarkably stable, meaning the product stays effective from the first drop to the last.
Benefits include:
- Longer shelf life
- Consistent results
- Less risk of irritation from oxidized vitamin C
This makes it ideal for a face oil formula.
4. Supports a More Even-Looking Skin Tone
THD Vitamin C is a powerful yet gentle brightener. It helps to:
- Soften the appearance of dark spots
- Improve uneven tone
- Reduce dullness
- Enhance natural radiance
It works gradually and harmoniously with the skin—perfect for a pro-aging approach.
5. Helps Support Collagen and Firmness
THD is shown to support collagen-producing pathways, helping improve:
- Skin firmness
- Elasticity
- Smoothness
The result is skin that feels supported, resilient, and radiant—not younger, but stronger and beautifully nourished.
