Restore radiance and fight visible signs of ageing with C-Tetra, a super-light daily vitamin C serum. Antioxidant power is provided through vitamin C and E. Together, these actives help to combat sun and pollution-induced damage. The lightweight, uplifting formula stimulates the production of collagen and elastin to help reduce fine lines and wrinkles, as well as visibly brightening the complexion and balancing skin tone. Using a lipid-soluble form of vitamin C called tetrahexyldecyl ascorbate, the formula penetrates deep into skin to provide powerful antioxidant protection with minimal irritation. C-Tetra has been carefully crafted in a water-free formula to be 100% stable, which means that the vitamin C does not degrade over time. This ensures that your formula remains highly potent from the very first use to the final drop.
Formulated with nourishing, pampering oils combined with the anti-ageing power of vitamin C, this fast-absorbing vitamin C serum is ideal for those looking for skin rejuvenation. Perfect for those who are new to vitamin C, or are looking to upgrade from C-Tetra Cream or Daily Radiance Vitamin C. 
After cleansing in the morning, massage 4 drops across the face, neck and décolletage. Leave to absorb before applying moisturiser.
Tetrahexyldecyl Ascorbate – A lipid-soluble form of vitamin C that provides exceptional antioxidant protection from harmful free radicals, while stimulating collagen production for a youthful complexion.
Vitamin E – A lipid-soluble antioxidant that is naturally present in the skin. Vitamin E protects the skin from free radicals and is regenerated by vitamin C for optimum power.

Here's how to incorporate this antioxidant serum into your skincare routine: After cleansing and toning your skin in the morning, dispense 4-6 drops into the palm of your hand.
Gently massage the serum evenly across your face, neck, and décolletage.
Allow the serum to absorb fully before applying your moisturizer and sunscreen.
For optimal results, use this serum daily in the morning.
A little goes a long way, so start with a smaller amount and adjust as needed.
If you are new to vitamin C serums, you may experience a slight tingling sensation upon application; this is normal and should subside with continued use.
Store the product in a cool, dark place to protect its potency. Remember to always follow with a broad-spectrum sunscreen to protect your skin from sun damage.

Top Notes: This serum likely presents with a light, citrusy aroma from the tetrahexyldecyl ascorbate (vitamin C). While not a traditional fragrance, this form of vitamin C can have a subtle, tangy scent, potentially accompanied by a slightly oily note from the base formulation.

Heart Notes: As the serum absorbs, the initial citrus notes may soften, giving way to the subtler characteristics of the formula. The vitamin E may contribute a mild, almost imperceptible, nutty or slightly sweet nuance.

Base Notes: C-Tetra is described as having a lightweight, oil-based formula. Therefore, the lingering scent is likely to be a delicate blend of the carrier oils used, creating a smooth, skin-like aroma. This could be described as subtly warm and slightly oily, but overall very neutral and unobtrusive.

Ingredients:
Tetrahexyldecyl Ascorbate, Cyclopentasiloxane, Cyclohexasiloxane, Tocopherol, Caprylic/Capric Triglyceride, Linoleic Acid, Linolenic Acid, Ubiquinone. WARNINGS: This product contains Vitamin C, which may cause a mild tingling sensation upon application, especially on sensitive skin. This is normal and should subside quickly. Perform a patch test before first use, especially if you have sensitive or reactive skin. Apply a small amount of product to an inconspicuous area, such as the inner forearm, and wait 24 hours to observe for any adverse reactions. Discontinue use if irritation, redness, or itching occurs. Avoid contact with eyes. If contact occurs, rinse thoroughly with water. This product is for external use only. Do not ingest. Keep out of reach of children. Store in a cool, dark place away from direct sunlight. Vitamin C serums can increase photosensitivity, so it's important to apply a broad-spectrum sunscreen with an SPF of 30 or higher during the day while using this product and for a week after discontinuing use. Consult with a dermatologist if you have any concerns or pre-existing skin conditions.
