Ascorbic Acid is is pure Vitamin C. This form makes up the largest amount of vitamin C found naturally in our skin.

Not only is vitamin C great for your overall health and immune system, it also has plenty of benefits on your skin.

Vitamin C is best used for brightening skin. It improves dark spots, acne scars, and hyperpigmentation. This is because it blocks the process of skin darkening when exposed to UV.

Remember: Vitamin C should not replace sunscreen!

Your skin uses vitamin C to build collagen. Collagen is one key component in having a strong skin barrier and plump skin. Vitamin C also plays a role in regulating collagen, thus making it effective in improving wrinkles and fine lines.

Ascorbic acid shows potent antioxidant activity. As an antioxidant, it helps fight free-radicals. Free-radicals are molecules that may damage your skin cells. These antioxidants also protect skin against UV damage.

The best formulations include Vitamin E and/or ferulic acid. These two ingredients help stabilize and provide a boost in the benefits of ascorbic acid. This is because ascorbic acid becomes unstable when exposed to UV and air. In fact, you can tell your ascorbic acid has oxidized when it turns an orange-yellow color.

Ascorbic acid is generally compatible with other ingredients. However, using ascorbic acid with other active ingredients might cause irritation. Two ingredients: copper ions and benzoyl peroxide, will inactivate ascorbic acid completely.

Ubiquinone (Coenzyme Q10) is a molecule already found in our bodies. It is a potent antioxidant and skin-soothing ingredient.

Aging and environmental exposure diminishes our skin's natural ubiquinone levels. This is much like our natural collagen and elastin.

The good news is: studies show applying this ingredient topically replenishes ubiquinone levels in our skin. This also comes with a ton of skin benefits. These benefits include:

Ubiquinone is considered a large molecule and cannot be absorbed into the lower layers of skin. This is why it is believed to be such an effective antioxidant: it protects our skin in the upper layers and prevents damage in the deeper layers.

When used in sunscreen, ubiquinone is shown to increase ingredient stability, increase SPF factor, and add to infrared protection.

Fun fact: ubiquinone is fat-soluble.

The best brightening serum ever!
This serum contains 4% tranexamic acid, 5% niacinamide, 5% Panthenol, and 60% Vaccinium Vitis-Idaea, Alpha-albutin, bisabolol and more! So many goodies all at a good concentration that is effective but not irritating (you don't need 10% niacinamide!!!) it's a perfect addition to my morning routine and I will definitely be repurchasing. It's very effective and works quickly at brightening. It's also not massively expensive, I payed about £16/$19 + a discount (so it was slightly less than this). Numbuzins products are killing it lately with this product, the new sunscreen and the matching toner it's quickly becoming one of my favourite brands!
