Product Summary
"Karam MD - Quench" is effective for: Moisturizing
Ingredient callouts
- Panthenol (pro-vitamin B5) at about 2.10% - 3.10% concentration. In this concentration, Panthenol works effectively to improve the skin barrier and reduce inflammation.
- Humectants (trehalose 0.60% - 1.40%, glycerin 1.70% - 2.60%, panthenol 2.10% - 3.10% and sodium hyaluronate 2.60% - 4.00%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
Moisturizing
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, sodium hyaluronate.
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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin
A sugar that attracts water to the upper layer of the skin
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
Helps attract water to the upper layer of the skin and can help improve skin barrier function
Used to preserve products, dissolve other ingredients and create a nice product texture
Traditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin
Pure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself
Can contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation
Anti-oxidation
This product contains antioxidants (epilobium angustifolium flower/leaf/stem extract) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
A plant extract that might contain antioxidants
A plant extract that can help lighten the skin and calm down inflammation. Might be helpful in neutralizing free radicals
Pure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself
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.
A more stable but less potent derivative of vitamin C. It can help neautralize free radicals and even out the skin tone if used in high enough concentration (required levels are likely to be much higher than for pure vitamin C, and solid studies are lacking at the moment)

A derivative of vitamin C that is more stable, but less bioavailable than the pure form of vitamin C. It does not penetrate the skin well, but has been shown to convert to pure vitamin C once in skin. It can be helpful in stimulating collagen production and lightening the skin tone, but the required concentration is likely to be very high
