Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Antioxidant, Buffering, Masking

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.

Humectant, Skin Conditioning, Skin Protecting

Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.

A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.

As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.

Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.

Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.

In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.

This ingredient is organic, colorless, odorless, and non-toxic.

Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

Other than Obagi Vitamin C + Hydroquinone, this is the best Vitamin C I’ve used. I took a break from the Obagi about 6 months ago because of the hydroquinone. Since then I’ve used Naturium, Vichy, the Ordinary, and Purador. In a week, the Purador gave me a glow and brightened my skin. I can tell a huge difference. It’s my new go to when I’m not using Obagi!

It’s almost only natural ingredients hence the smell and sediment. Huge bottle for that price!
Shake a lot at first use and shake few times before any use to have smooth texture. It gets awesome golden color. manufacturer suggest to use it in the evening. Probably because of retinol. After first use my skin felt numb, which is a good indicator that it’s a strong serum. So be aware to use good Show more

I was not very knowledgable about skincare when I first tried this product, so I can't fault it for that, but I have to say it was extremely irritating for me.

If you're new to skincare and are looking for something for acne, I do not think you should start with this.

I'm honestly not sure what is in this that is supposed to treat acne besides Niacinamide, which I've come to suspect my Show more

I’m not sure if this did anything in terms of lightening acne marks but it may have contributed to one of the worst breakouts of my life. It has a mild citrus scent and is a gel that absorbs well without stickiness but nope it doesn’t work.
