COSRX The RX The Vitamin C 23 vs. BIOSSANCE Squalane + Vitamin C Rose Oil
Position 1

#1Water

Origin: natural
Role: Solvent
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.

-- versus --

#1Squalane

Origin: natural
Role: Skin conditioning agent, Emollient, Hair conditioning
Softening
Comedogenic rating [ 1 ]
EWG Rating [ 1 ]
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.

Position 2

#2Ascorbic Acid (Vitamin C)

Origin: chemical
Role: Skin conditioning agent, Buffering agent, Fragrance ingredient, Masking

Good for dry skin

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.

#4Dimethicone

Origin: chemical
Role: Skin conditioning agent, Antifoaming agent, Emollient
Silicones
EWG Rating [ 1 ]
CIR Rating [ A ]

Dimethicone is the most popular silicone. It makes the skin softer and forms a film adding smooth and silky feeling. This film not only improves how the skin feels but also works as a protective barrier. It also improves the visual appearance of your skin by filling small wrinkles. What you should really know is that this component is difficult to wash off! So make sure you did proper cleansing after using it.

-- versus --

#5Caprylic/Capric Triglyceride

Origin: natural
Role: Skin conditioning agent, Fragrance ingredient
EWG Rating [ 1 ]
CIR Rating [ A ]

Caprylic/Capric Triglyceride is an emollient that also hydrates the skin without leaving a fatty film. When applied, the component feels smooth and light. In haircare products, it’s also used for hydrating purposes. It makes hair silky, lowers tangling, and makes hair smooth.

It’s safe for most people, except for people with allergic reactions to coconut or palm oil because these oils are usually used for producing the component.
