Key actives
Product Summary
"Theramid - Tetramid C. E. F" could be helpful for: Anti-aging, Evens skin tone and Moisturizing, but its actives are not the most effective or are not well-studied.
Ingredient callouts
- Humectants (glycerin 2.20% - 3.20%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
Anti-oxidation
This product contains antioxidants (ascorbyl tetraisopalmitate, ferulic acid) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
The following ingredients - ascorbyl glucoside also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.
A potent anti-oxidant that has been shown to be effective in neutralizing free radicals in skin. There seem to have a synergetic effect of ferulic acid, vitamin E and C, meaning that when the ingredients are used together, they enhance each other's ability protect the skin against free radicals. Ferulic acid also helps to stabilize other ingredients - including vitamins C and E. It can help to even out the skin tone. Ferulic acid is approved for use as a sunscreen ingredient in Japan in concentrations up to 10%
A vitamin C derivative. Studies show that is might be effective in reducing hyperpigmentation, but there are no studies confirming that it is effectively converted into the bioavailable form of Vitamin C in skin. It is not clear how this derivative compares in effectiveness to the topical application of bioavailable form of vitamin C (L-ascorbic acid)
A vitamin C derivative that is more stable but less potent than pure form of vitamin C. Has a potential to boost collagen production, nutralise free radicals and reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products
An emollient that helps soften the skin. Might be somewhat helpful in evening the skin tone.
A stable derivative of pectin and vitamin C. It might help neutralize free radicals in skin, but evidence of effectiveness is lacking. Helps create a thicker product consistency and stabilize the product formulation
A more stable but less bio-available form of vitamin E compared to Tocopherol. Might help moisturize and protect the skin from free radicals, but mostly used in low concentrations to stabilize other ingredients.
Anti-aging
What does the product description say?
Here, its action is focused on melanocytes (to treat blemishes from the inside) and on collagen synthesis (to prevent and fight wrinkles from the inside).

An emollient that helps soften the skin. Might be somewhat helpful in evening the skin tone.
Moisturizing
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin.
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).
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
An emollient that helps soften the skin. Can increase penetration of other ingredients
