Key actives
Product Summary
"Joanna Czech Skincare - The C+ Serum" could be helpful for: Moisturizing and Evens skin tone, but its actives are not the most effective or are not well-studied.
Ingredient callouts
- Humectants (glycerin 0.10% - 0.35% and cylindrotheca fusiformis extract 0.85% - 1.25%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
Evens skin tone
What does the product description say?
Lightweight and fast-absorbing, THE C+ SERUM contains a stable form of Vitamin C. It is an anti-inflammatory, that helps to increase collagen production, hydrates, brightens, evens out skin tone, and inhibits melanin synthesis.

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: dimethylmethoxy chromanyl palmitate.
An oil-soluble compound that has been shown in laboratory studies (in a petri dish, not on human volunteers) to inhibit melanin production in skin and help even out the skin tone. More research is needed to understand if it works in real life
Being a lipid soluble form of vitamin C, it is more stable than ascorbic acid, but still degrades quickly and needs to be stabilized in a formulation with another ingredient. It is claimed to penetrate skin better than pure vitamin C and have the the similar benefits, but solid studies of its effectiveness are lacking. Is likely to require a higher concentration in a product than pure vitamin C to be effective. It might be able to help reduce pore clogging.

This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
cylindrotheca fusiformis extract, glycerin.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: caprylic/capric triglyceride, helianthus annuus seed oil.
A good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin
Helps skin moisturization by attracting water to the upper layer of the skin. Might have some anti-oxidant properties but research confirming effectiveness in skin is lacking

Anti-aging

Effective ingredients missing or their concentration is too low.
Being a lipid soluble form of vitamin C, it is more stable than ascorbic acid, but still degrades quickly and needs to be stabilized in a formulation with another ingredient. It is claimed to penetrate skin better than pure vitamin C and have the the similar benefits, but solid studies of its effectiveness are lacking. Is likely to require a higher concentration in a product than pure vitamin C to be effective. It might be able to help reduce pore clogging.
Exfoliation
This product does not contain effective exfoliating ingredients. It might be able to deliver physical exfoliation, that is scrub off some of the dead cells on the surface of the skin. We do not recommend physical exfoliation, because it is not uniform (some bits of skin can get exfoliated too much while others not at all). It can also traumatize the skin and aggrevate acne and other skin conditions.
