Ingredients Explained

These ingredients are found in both products.

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

Humectant, Masking, Skin Conditioning

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

Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.

Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.

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.

Skin Conditioning, Solvent

1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse. 

It is a:

  • Humectant, drawing moisture into the skin
  • Emollient, helping to soften skin
  • Solvent, dispersing and stabilizing formulas
  • Preservative booster, enhancing the antimicrobial activity of other preservatives 
Smoothing

Niacinamide is a multitasking form of vitamin B3 that strengthens the skin barrier, reduces pores and dark spots, regulates oil, and improves signs of aging.

And the best part? It's gentle and well-tolerated by most skin types, including sensitive and reactive skin.

You might have heard of "niacin flush", or the reddening of skin that causes itchiness. Niacinamide has not been found to cause this.

In very rare cases, some individuals may not be able to tolerate niacinamide at all or experience an allergic reaction to it.

If you are experiencing flaking, irritation, and dryness with this ingredient, be sure to double check all your products as this ingredient can be found in all categories of skincare.

When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.

When you apply niacinamide to your skin, your body converts it into nicotinamide adenine dinucleotide (NAD). NAD is an essential coenzyme that is already found in your cells as "fuel" and powers countless biological processes.

In your skin, NAD helps repair cell damage, produce new healthy cells, support collagen production, strengthen the skin barrier, and fight environmental stressors (like UV and pollution).

Our natural NAD levels start to decline with age, leading to slower skin repair, visible aging, and a weaker skin barrier. By providing your skin niacinamide, you're recharging your skin's NAD levels. This leads to stronger, healthier, and younger looking skin.

Another name for vitamin B3 is nicotinamide. This vitamin is water-soluble and our bodies don't store it. We obtain Vitamin B3 from either food or skincare. Meat, fish, wheat, yeast, and leafy greens contain vitamin B3.

The type of niacinamide used in skincare is synthetically created.

Melia Azadirachta Flower Extract is from the Neem tree. Neem trees originate from India.

Melia Azadirachta Flower Extract contains antioxidants. Antioxidants help fight free-radicals. Free-radicals are molecules that may damage your skin cells, such as pollution.

The flowers of this tree are lilac colored.

Skin Conditioning

Ocimum Sanctum Leaf Extract comes from the Holy Basil plant. Holy Basil is native to India.

Holy Basil is rich in antioxidants due to its high romarinic acid, ferulic acid, and rutin content. This gives it skin brightening and soothing properties.

While Holy Basil has many claims to help fight acne, more research is needed.

One thing to note is the presence of tannins; tannins are naturally found in nature. However, this compound may be skin-sensitizing.

Skin Conditioning

Melia Azadirachta Leaf Extract is extract from the neem plant.

The leaves of this tree contain flavonoids and polyphenols. These two compounds are antioxidants, anti-inflammatory, and antibacterial. Further research is needed as to their effects when applied on skin.

Skin Conditioning

Corallina Officinalis Extract is from the red seaweed, Corallina Officinalis. This seaweed is found all over the world but is most common in the rocky shores of Great Britain and Ireland.

Corallina Officinalis Extract contains antioxidant and emollient properties.

Extracted polysaccharides, galactose and xylose, in red algae showed antioxidant activity. Antioxidants help with anti-aging by neutralizing free-radical molecules. Free-radical molecules may damage your skin cells and DNA. Galactose is also a PHA.

Corallina Officinalis is structurally similar to coral due to its high calcium content.

Humectant, Skin Conditioning

Sodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.

Like hyaluronic acid, it is great at holding water and acts as a humectant. This makes it a great skin hydrating ingredient.

Sodium Hyaluronate is naturally occurring in our bodies and is mostly found in eye fluid and joints.

These are some other common types of Hyaluronic Acid:

Skin Conditioning, Solvent

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!

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.

This broke me out, which was disappointing after seeing so many good reviews. Not really sure why! I have combo acne prone skin. I switched to natrium vitamin c instead and really liked it
