Element Eight O₂ Vitamin C

The Oxygen-Enhanced Vitamin C Treatment for Clarity and Defence

Element Eight O₂ Vitamin C Brighten & Defend Serum is an advanced antioxidant face serum designed to visibly improve dark spots, uneven tone and dullness while helping defend the skin from oxidative stress.

Its silky, lotion-like texture combines THD Ascorbate—a lipid-soluble vitamin C derivative—with patented liquid oxygen and microencapsulated ferulic acid. The complexion appears clearer, brighter and more even, while the skin feels smooth, comfortable and beautifully refined.

Why It Is Different

O₂ Vitamin C Brighten & Defend Serum is more than a traditional vitamin C serum.

Many vitamin C formulas rely on pure L-ascorbic acid, which typically requires a low-pH environment and may feel acidic or irritating on sensitive skin.

Element Eight instead uses Tetrahexyldecyl Ascorbate, also known as THD Ascorbate. This lipid-soluble vitamin C derivative is designed to provide antioxidant and tone-refining benefits within a more comfortable, lotion-like formula.

THD Ascorbate is paired with microencapsulated ferulic acid to support antioxidant performance and formula stability. Element Eight’s patented Oxygen Amplified Therapy™ completes the formulation, creating an unusual relationship between vitamin C, ferulic acid and dissolved molecular oxygen.

The result is a sophisticated vitamin C serum that feels silky and nourishing rather than watery, sticky or overly acidic.

How It Works

O₂ Vitamin C Brighten & Defend Serum combines oxygen-delivery technology with a carefully constructed antioxidant and tone-correcting system.

• OATH™ Oxygen Amplified Therapy uses topical oxygen carriers that hold dissolved molecular oxygen and are designed to support the skin’s natural renewal environment.
• THD Ascorbate provides antioxidant support while helping visibly improve dark spots, uneven tone, dullness and loss of firmness.
• Microencapsulated Ferulic Acid helps defend against free-radical damage while complementing the stability and performance of the vitamin C derivative.
• Oligopeptide-68 helps support a clearer and more even-looking complexion.
• Vitamin E provides complementary antioxidant and conditioning care.
• Bisabolol helps soothe the complexion and maintain skin comfort.
• Rosehip, evening primrose and grape-seed oils provide replenishing lipids and additional antioxidant support.
• Pomegranate and Angelica extracts help condition skin affected by environmental stress.

How to Use

1. Morning and/or evening, apply O₂ Vitamin C Brighten & Defend Serum after cleansing and essence.
2. Dispense one pump and smooth it evenly over the face and neck.
3. Allow the serum to absorb before applying moisturizer.
4. Follow with the Element Eight moisturizer best suited to your skin.
5. Apply broad-spectrum sunscreen every morning.

For the most intentional use, we recommend applying it in the morning as part of the skin’s daily antioxidant ritual.

On evenings when using retinol or exfoliating acids, Element Eight recommends skipping O₂ Vitamin C and returning to it the following morning.

Complete Element Eight Antioxidant Ritual

1. Cleanse with your preferred facial cleanser
2. Mist O₂ Exosome Eight Active Essence over the face and neck
3. Allow the essence to settle, then gently press it into the skin
4. Apply O₂ Vitamin C Brighten & Defend Serum

7. Apply broad-spectrum sunscreen every morning

Loshen & Crem’s Recommendation

O₂ Vitamin C Brighten & Defend Serum is best suited to someone wanting to address visible dark spots, dullness and uneven tone while building greater antioxidant support into the morning routine.

We especially appreciate it for clients who understand the value of vitamin C but have struggled with traditional L-ascorbic acid formulas that feel acidic, sticky or uncomfortable.

Vitamin C is not simply vitamin C. Its form, supporting antioxidants, delivery system, packaging and complete formulation all influence how it behaves on the skin.

Use one pump consistently each morning rather than applying a larger amount occasionally. Visible discoloration develops over time, and improving it requires the same patience and consistency.

Most importantly, vitamin C does not replace sunscreen. Antioxidants help support the skin against oxidative stress, while sunscreen remains essential for limiting the UV exposure that contributes to new and recurring dark spots.

The Difference Between Brightening and Lightening

• Brightening is about improving dullness, uneven tone and the appearance of existing discoloration.
• Lightening or bleaching implies changing the skin’s natural colour.
• O₂ Vitamin C is designed to help the complexion appear clearer, more even and more luminous.
• It does not bleach the skin or remove its natural pigment.
• THD Ascorbate, ferulic acid and Oligopeptide-68 help address areas of visible discoloration while antioxidant ingredients support the entire complexion.
• The goal is not lighter skin. It is skin that looks more balanced, rested and radiant.

OATH™ stands for Oxygen Amplified Therapy™. It is Element Eight’s patented system of topical oxygen carriers designed to hold and deliver dissolved molecular oxygen into the skin.

What does ferulic acid do?
Ferulic acid is an antioxidant that helps defend against free-radical damage. In this formula, it is microencapsulated to support stability and complement the vitamin C derivative.

Does O₂ Vitamin C Serum help dark spots?

Does vitamin C replace sunscreen?
No. Vitamin C provides antioxidant support, but it does not replace broad-spectrum sunscreen.

The formula uses THD Ascorbate rather than low-pH L-ascorbic acid and includes soothing bisabolol. Sensitive skin should still introduce it gradually and adjust frequency according to comfort.

Can O₂ Vitamin C Serum be used every day?
Yes. It may be used once or twice daily, although Loshen & Crem especially recommends it as a consistent morning antioxidant treatment.

Can it be used with O₂ Niacinamide Serum?

Can it be used with retinol?
Element Eight recommends skipping O₂ Vitamin C during evenings when retinol is applied and returning to it the following morning.

O₂ Vitamin C is primarily a daytime antioxidant and tone-refining treatment. O₂ Retinol is a nighttime renewal serum focused more intensively on wrinkles, texture and firmness.

In the same consumer study, 85% agreed that dark spots appeared reduced after two weeks. More established discoloration generally requires longer and consistent use. Individual results may vary.

Use one pump, approximately 0.5 ml, over the entire face and neck.
