Why Oil-Soluble Vitamin C?

Unlike water-based L-ascorbic acid serums that oxidize and turn brown, this oil-based formulation uses tetrahexyldecyl ascorbate—a lipid-soluble vitamin C that remains stable at skin-compatible pH, doesn't sting, and delivers through your skin's natural lipid matrix for visible brightening results.

How to Use

Where it fits in your routine: Apply after cleansing and water-based serums, before or after moisturizer depending on your skin type.

Quick Application (30 seconds)

1. After cleansing, apply 3-4 drops to face and neck
2. Use morning and/or evening
3. Morning: Follow with SPF 30+ for comprehensive photoprotection
4. Evening: Layer under or over moisturizer

Pro Tip

For oily skin, this may be sufficient on its own or under SPF. For dry skin, layer it under a richer moisturizer. Vitamin C works gradually—most people notice brighter, more radiant skin within 8-12 weeks of consistent daily use.

Premium Ingredients

Active Ingredient

Tetrahexyldecyl Ascorbate (3%)
A lipid-soluble vitamin C derivative that dissolves in oils rather than water. This structure allows it to integrate into skin's lipid barrier and remain stable without oxidizing. Clinically studied for brightening, evening tone, and supporting collagen synthesis.

Barrier-Supportive Base Oils

Milk Thistle Seed Oil
~60% linoleic acid (omega-6) – High linoleic acid content with notably dry skin feel. Contains silymarin antioxidants. Absorbs quickly without residual oiliness.

Ximenia Oil
~40% ximenynic acid (C26 omega-6) – Rare African seed oil with very long-chain fatty acids (C30-C40) for rapid absorption and light texture.

Abyssinian Oil
~60% erucic acid (omega-9) – High in long-chain monounsaturated fatty acids that provide slip and oxidative stability with non-greasy texture.

Frequently Asked Questions

Q: How is this different from water-based vitamin C serums?
A: Most vitamin C serums use L-ascorbic acid dissolved in water, which requires low pH (around 3.5) and oxidizes when exposed to light and air, turning brown and losing potency. This oil-based formula uses tetrahexyldecyl ascorbate, which remains stable at skin-compatible pH, doesn't oxidize readily, and penetrates through your skin's lipid layers. Read our complete comparison →

Q: Can I use this if I have oily or acne-prone skin?
A: Yes! The milk thistle base oil has a notably dry, non-greasy feel and is high in linoleic acid—a fatty acid that research shows oily skin types are often deficient in. The formulation absorbs quickly without leaving residue, making it suitable for all skin types.

Q: Does this need to be refrigerated?
A: No. Unlike water-based L-ascorbic acid serums that degrade quickly, tetrahexyldecyl ascorbate is stable at room temperature. Store in a cool, dry place away from direct sunlight.

Q: How long until I see results?
A: Most people notice brighter, more radiant skin within 8-12 weeks of consistent daily use. Individual results vary based on skin type, routine, and environmental factors.

Q: Can I use this with retinol or other actives?
A: Yes. Oil-soluble vitamin C is generally well-tolerated with other actives. You can use it in the same routine as retinoids, niacinamide, or AHAs/BHAs. Consider applying vitamin C in the morning (with SPF) and retinol at night.

Q: Why only 3% vitamin C when other serums have 10-20%?
A: Concentration percentages aren't directly comparable between water-soluble and oil-soluble forms. Tetrahexyldecyl ascorbate is lipophilic and penetrates differently than L-ascorbic acid. Research shows 3% provides effective results without irritation. Higher isn't always better—stability and bioavailability matter more than percentage. Learn more about effective dosing →

Q: Do I apply this before or after moisturizer?
A: Either works. For oily skin, this may be sufficient on its own or under SPF. For dry skin, layer it under a richer moisturizer. Experiment to find what works best for your skin.

Q: How many drops should I use?
A: 3-4 drops is sufficient for face and neck. One 1oz bottle should last approximately 2-3 months with daily use.
