Ingredients Explained

These ingredients are found in both products.

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

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!

Humectant, Masking, Skin Conditioning

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.
  • It has mild preservative properties.

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

Emulsion Stabilising, Gel Forming

Carbomer is a polymer of acrylic acid. Its main role is to create a gel consistency.

A high amount of carbomer can cause pilling or balling up of products. Don't worry, most products contain 1% or less of carbomer.

I got a sample of this and saw that it was FA safe and had no comedogenic or irritating ingredients so I tried it out. Only used it 4 times, but it was pretty obvious what a powerful humectant beta-glucan is. Just pure hydration and calm. Definitely buying the full size if I need the extra hydration. In this regard, it beats the skin1004 madagascar centella ampoule! (Still love that for beneficial Show more

Very hydrating, my must have product
Wow. I regret not buying this earlier. It's a somewhat thick serum that's very moisturizing and absorbs nicely into the skin,depending how much you use. I go heavy on this and put a full dropper on my face and it takes a while but it does sink in.

It has helped with my rosacea flareups and dry patches.

It's niacinamide free so it's a great hydrating Show more

Used for over 5 years, never had any problems. Makes skin feel dewy, bouncy, and refreshed and layers well with other skincare and under makeup.
