Hydroquinone is used to treat hyperpigmentation, acne scars, and age spots.

It works by decreasing the melanocytes in your skin. Melanocytes are cells that create melanin (the color pigment in skin).

Be sure to use this ingredient as prescribed by your doctor. Wearing sunscreen is also a must (you should be wearing sunscreen anyway!).

Most hydroquinone prescriptions are not to be used for longer than 3 months. Long term usage can cause ochronosis, or a condition in which the skin darkens more than before.

This ingredient is banned in the EU for being skin sensitizer. In the US, this ingredient is not allowed for over-the-counter sale.

However, it is still possible to get hydroquinone in the EU, US, Canada, Australia, and Japan from a doctor's prescription.

There is no known research backing this ingredient to be carcinogenic in humans.

Gentle reminder that all skin tones are beautiful!

Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.

You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Stay hydrated!

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.

Foods rich with vitamin C include oranges, strawberries, broccoli, bell peppers, and more. When consuming Vitamin C, your skin receives a portion of the nutrients.
