Ingredients Side-by-side
Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
7 Benefits 2 Concerns
Glycolic Acid is arguably the most famous AHA with a ton of research to back up its benefits.
6 Benefits
Niacinamide has emerged as an all-star ingredient due to its many benefits.
Sodium Hydroxide is also known as lye or caustic soda. It is used to adjust the pH of products; many ingredients require a specific pH to be effective.
1,2-Hexanediol is a multi-tasker ingredient. It acts as a preservative to increase shelf-life and can aid other preservatives in preventing microbe growth. 1,2-Hexanediol also helps the skin retain moisture as a humectant.
Panthenol is a common ingredient that helps hydrate and soothe the skin. It can be found naturally in our skin and hair.
Sodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.
Xanthan gum is used as a stabilizer and thickener within cosmetic products. It helps give products a sticky, thick feeling - preventing them from being too runny.
Helps fight Acne 4 Concerns
Benzoyl Peroxide is famous for fighting acne. This is because it does a variety of tasks on the skin: it helps reduce excess oil, kill bacteria, and clear out dead skin cells. In other words, it is effective at unclogging pores.
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.
A type of fatty alcohol. Fatty Alcohols are most often used as an emollient or to thicken a product. They are usually derived from natural fats and oils and therefore do not have the same drying or irritating effect as traditional alcohols.
Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.
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.
2 Concerns
Silica is a mineral naturally found in our skin. It helps to thicken and smooth the texture of a product. It also acts as an agent for other ingredients by increasing the absorption of other ingredients into the skin.
Carbomer is a polymer of acrylic acid. Its main role is to create gel consistency within products.
Capryloyl Salicylic Acid comes from salicylic acid, the famous acne-fighting BHA.
Potassium hydroxide is commonly known as caustic potash. It is used to fix the pH of a product or as a cleaning agent in soap. In cleansers, it is used for the saponification of oils.
Antioxidant Helps brighten skin
Tocopheryl Acetate is AKA Vitamin E. It is an antioxidant and protects your skin from free radicals. Free radicals damage the skin by breaking down collagen.
Acrylates/C10-30 Alkyl Acrylate Crosspolymer is a synthetic polymer. It is used to thicken and improve the texture of products.
Disodium EDTA plays a role in making products more stable by aiding other preservatives.

Great spot treatment but expensive
I used it as a spot treatment and it worked beautifully for me. I have sensitive combo skin and every time I’ve got some whitehead i used it on it and in it disappeared. Definitely wouldn’t use it every day or as a moisturiser. The only reason why i don't like it is, because it's really expensive.
