Ingredients Explained

These ingredients are found in both products.

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

Ascorbic Acid

What it does: Antioxidant, Buffering, Masking, Skin Conditioning

Community Rating: Loved

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.

Read more about other types of Vitamin C:

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.

Numbuzin No.5 Vitamin Concentrated Serum contains this as ingredient number 37.

Butylene Glycol

What it does: Humectant, Masking, Skin Conditioning, Solvent

Community Rating: Mixed

Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:

It is a solvent, meaning that it helps to dissolve other ingredients. This also enhances the absorption of the product into one's skin.
It is a humectant, which means that it helps attract moisture into the skin.
It helps improve product application.

Overall, Butylene Glycol is a safe and well-rounded ingredient. It is unlikely to irritate skin, and works well with pretty much all other ingredients.

Benton Vitamin C Serum contains this as ingredient number 3.

Numbuzin No.5 Vitamin Concentrated Serum contains this as ingredient number 2.

Glycerin

What it does: Humectant, Skin Conditioning, Skin Protecting, Solvent

Community Rating: Loved

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.

Pentylene Glycol

What it does: Skin Conditioning, Solvent

Community Rating: Mixed

Pentylene glycol is typically used within a product to thicken it. It also adds a smooth, soft, and moisturizing feel to the product. It is naturally found in plants such as sugar beets.

The hydrophilic trait of Pentylene Glycol makes it a humectant. As a humectant, Pentylene Glycol helps draw moisture from the air to your skin. This can help keep your skin hydrated.

This property also makes Pentylene Glycol a great texture enhancer. It can help thicken or emulsify a product. Emulsifiers help stabilize a product. It does this by preventing certain ingredients from separating.

Pentylene Glycol also acts as a mild preservative and helps to keep a product microbe-free.

Some people may experience mild eye and skin irritation from Pentylene Glycol. We always recommend speaking with a professional about using this ingredient in your routine.

Pentylene Glycol has a low molecular weight and is part of the 1,2-glycol family.

3-O-Ethyl Ascorbic Acid

What it does: Skin Conditioning

Community Rating: Liked

You might know this ingredient as Ethyl Ascorbic Acid, a more stable version of ascorbic acid.

Like other types of vitamin C, this ingredient has many benefits including reducing wrinkles, skin soothing, dark spot fading, and fighting against free radicals.

3-O-Ethyl Ascorbic Acid interferes with the process of skin darkening, helping to reduce hyperpigmentation. It also encourages the skin to produce more collagen.

Once applied, 3-O-Ethyl Ascorbic Acid is converted to Vitamin C deeper in the skin's layers. This process is slow but makes this ingredient more tolerable for skin.

The optimum pH range for this ingredient is 4 - 5.5

Numbuzin No.5 Vitamin Concentrated Serum contains this as ingredient number 25.

lt is a humectant, meaning that it helps the skin attract and retain moisture.

Adenosine

What it does: Skin Conditioning

Glutathione

What it does:

Community Rating: Loved

Glutathione is an antioxidant naturally found in our bodies. It is made up of three amino acids: glycine, cysteine, and glutamic acid.

As an antioxidant, it prevents oxidative damage to parts of our cell.

While glutathione is said to help with skin lightening, the results from research are inconclusive. Further studies are needed.

However, gluthatione has been shown to protect our skin from UV-B induced damage.

This ingredient is naturally occurring in plants, animals, fungi, and some bacteria.

Tocopherol

What it does: Antioxidant, Masking, Skin Conditioning

Community Rating: Liked

Tocopherol (also known as Vitamin E) is a common antioxidant used to help protect the skin from free-radicals and strengthen the skin barrier. It's also fat soluble - this means our skin is great at absorbing it.

Vitamin E also helps keep your natural skin lipids healthy. Your lipid skin barrier naturally consists of lipids, ceramides, and fatty acids. Vitamin E offers extra protection for your skin’s lipid barrier, keeping your skin healthy and nourished.

Another benefit is a bit of UV protection. Vitamin E helps reduce the damage caused by UVB rays. (It should not replace your sunscreen). Combining it with Vitamin C can decrease sunburned cells and hyperpigmentation after UV exposure.

You might have noticed Vitamin E + C often paired together. This is because it is great at stabilizing Vitamin C. Using the two together helps increase the effectiveness of both ingredients.

There are often claims that Vitamin E can reduce/prevent scarring, but these claims haven't been confirmed by scientific research.

The best brightening serum ever!

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!
