"C+Collagen Brighten and Firm Serum"

From product name

WIMJ summary

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

Ingredient	Effectiveness	Concentration	Irritancy
niacinamide	HIGH

WIMJ summary

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: mandelic acid, niacinamide

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: 3-o-ethyl ascorbic acid, emblica officinalis fruit extract, hexylresorcinol.

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

WIMJ summary

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: mandelic acid.

Ingredient	Effectiveness	Concentration	Irritancy
mandelic acid	HIGH
lactic acid	HIGH

WIMJ summary

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, glycine.

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: niacinamide

Ingredient	Effectiveness	Concentration	Irritancy
superoxide dismutase	HIGH
niacinamide	HIGH
collagen amino acids	HIGH

WIMJ summary

This product contains antioxidants (superoxide dismutase, ubiquinone) 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 - 3-o-ethyl ascorbic acid, emblica officinalis fruit extract, hexylresorcinol also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

Ingredient	Effectiveness	Concentration	Irritancy
ubiquinone	HIGH
superoxide dismutase	HIGH

Ingredients by volume

Ingredient	Estimated concentration
water Plain old water	45% - 55%
glycerin One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant	4.5% - 5.6%
3-o-ethyl ascorbic acid A vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help 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	4.3% - 5.2%
niacinamide Is proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture	3.1% - 3.7%
glycereth-7 triacetate	2.4% - 2.9%
lactic acid An exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiom)	1.9% - 2.3%
sd alcohol 40-b Can be drying and contribute to skin irritation. Used in formulars to dissolve other ingredients, create a thinner product consistency or for its antibacterial properties	1.6% - 1.9%
hydroxyethylcellulose Used to thicken product formulations and create gel-like textures	1.5% - 1.8%
dimethyl isosorbide Used to dissolve other ingredients in a product and can enhance their ability to penetrate the skin	1.2% - 1.4%
ascorbic acid The most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging	0.9% - 1.15%
collagen amino acids Help attract water to the upper layer of the skin, soften it and support the skin barrier function	0.65% - 1%
superoxide dismutase An antioxidant enzyme that is naturally present in skin. It can help support skin barrier function and reduce inflammation in skin. It is used in topical medications for inflammatory skin conditions including atopic dermatitis (eczema) and psoriasis. There are three types of natural Superoxide Dismutase in human skin. The compound used in topical treatments and cosmetics are mimics of typically one of these natural variants	0.55% - 0.8%
glycine Helps to attract water to the upper layer of the skin and can help restore the skin barrier function	0.5% - 0.75%
carnitine hcl Might be helpful in decreasing sebum production making the skin less oily. Is claimed to be able to support ceramide production in skin that leads to better hydration, but evidence is lacking. Is able to attract water to the upper layer of the skin	0.45% - 0.65%
ubiquinone Coenzyme Q10. It helps neutralize free radicals in skin, improves skin hydration and might be helpful agains fine lines and wrinkles. It can be an allergen	0.45% - 0.65%
hexylresorcinol Might be helpful in reducing hyperpigmentation and neutralizing free radicals in skin	0.45% - 0.65%
emblica officinalis fruit extract A plant extract that might be helping in neutralizing free radicals in skin. It could help reduce hyperpigmentation. There is some research to confirm its effectiveness in skin	0.35% - 0.65%
hydrolyzed soy protein Helps attract water to the upper layer of the skin. Might have some anti-aging, anti-oxidant, and skin lightening properties, but solid evidence is missing	0.35% - 0.6%
tetrahexyldecyl ascorbate 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.	0.3% - 0.6%
isoquercetin	0.3% - 0.5%
mandelic acid Helps shed the upper layer of dead cells from the surface of the skin revealing smoother, brighter skin. It can help to reduce hyperpigmentation. It has anti-bacterial properties, and might help to reduce blemishes, as well as fine lines and wrinkles. It is considered to be gentler than glycolic acid	0.25% - 0.5%
pueraria lobata root extract	0.25% - 0.45%
curcuma longa root extract A plant extract that can contain an active compound curcumin, that may have some anti-inflammatory properties when applied to the skin, but solid research is lacking and the typical concentration used in skincare products is too low. Can be an irritant	0.2% - 0.4%
phytic acid An alpha-hydroxy acid (AHA), but is mostly used to stabilize product formulations in cosmetics	0.25% - 0.45%
citric acid Can work as an exfoliant but is typically used to adjust the product pH	0.25% - 0.45%
tetrasodium edta Helps to stabilize the product formulation	0.25% - 0.45%
