Both products have the same component on this position.

#1Water

EWG Rating [ 1 ]

Water is a great solvent. It’s neutral and doesn’t provide any strong positive or negative effects. It just helps components to mix better and to transport active components.

Vitamin C is known for its strong antioxidant activity. It helps to slow down aging processes. The other positive effect of this ingredient is that it helps to make skin tone even. It's a great ingredient to counter dark areas and uneven skin tone. It's well-researched and considered safe. But it's acid and can irritate the skin if used too often.

CIR Rating [ A ]

Squalane is a more stable equivalent of Squalene. It is a very important component of our skin. It’s a major part of natural sebum that forms a protection barrier on the skin's surface. If the barrier isn’t strong enough, your skin will become more sensitive. Squalane helps to keep skin hydrated, protects it from the negative impact of the environment, lowers irritation, stimulates regeneration, and removes dryness. It is accepted by our skin very well and will not cause allergic reactions.

Glycerin is one of the most outstanding and helpful skincare components. It's used in many skincare products because it works and provides notable results. It's one of the best moisturizers. Molecules of Glycerin can absorb water and deliver it into deep layers of the skin making it hydrated.

The component is researched very well. Many scientific researches confirm the safety and the efficiency of the component.

Alcohols
EWG Rating [ 1 ]
Bad for dry skin
Bad for dry skin

Alcohol Denatured is a great bacteria killer. Manufacturers often put it inside products to increase their shelf life.

It’s one of the most harmful alcohols used in skincare. You should use it carefully, especially if you have dry skin. It removes oily barrier from the surface of your skin making it less protected and causing dryness. We advise you to pay attention to the position of this component in a formulation. If it stays below the 6th position it will hardly harm your skin. We also recommend testing the product first before application. If you feel a “cooling effect” it means the product contains a lot of alcohol and it's better to be careful with it.
