Does It Cosmetics Bye Bye Undereye Illumination Full Coverage Anti-Aging Waterproof Concealer work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using It Cosmetics Bye Bye Undereye Illumination Full Coverage Anti-Aging Waterproof Concealer:

  • Significant moisturizing. It has a moisturizing rating of 6.3 out of 10.
  • Little anti-wrinkle effect: It Cosmetics Bye Bye Undereye Illumination Full Coverage Anti-Aging Waterproof Concealer has an anti-wrinkle rating of 1.5 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.
  • Antioxidant protection.

Moisturizer with the right occlusivity for dry to very dry skin, ideally to be used with extra humectants

According to CreamScan analysis, It Cosmetics Bye Bye Undereye Illumination Full Coverage Anti-Aging Waterproof Concealer is highly moisturizing, with a moisturizing rating of 6.3 out of 10.

Is it more humectant or occlusive? Significantly more occlusive. It has a low Humectancy of 2.6 out of 10 and a maximum Occlusivity of 10 out of 10, due to the high content of Caprylic/Capric Triglyceride (est. ≈45.0%) and Microcrystalline Wax (est. ≈3.0%).

This type of product, when used as a standalone moisturizer, can deliver an exceptional level of occlusive hydration that is adequate for dry to very skin. The occlusive profile of It Cosmetics Bye Bye Undereye Illumination Full Coverage Anti-Aging Waterproof Concealer suggests a rich, thick texture, making it perfectly suited for dry skin.

However, it contains a relatively low level of humectants, and people with dry skin would definitely benefit from adding more humectants to their moisturizing routine beyond what this product offers. If this is your only moisturizer, it may be worth including a humectant-rich product, such as a serum, in your skincare routine.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Little anti-wrinkle efficacy

According to CreamScan analysis, It Cosmetics Bye Bye Undereye Illumination Full Coverage Anti-Aging Waterproof Concealer has a minimal anti-wrinkle rating of 1.5 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈1.0%), 
 one of the most effective and well-researched anti-wrinkle ingredients. A clinical study involving 30 participants (Kawada et al.) confirmed that a cream with 4% niacinamide reduced the average depth of wrinkles around the eyes by 9% after 8 weeks of use, compared to a vehicle (the same formulation without niacinamide).
 
Among others, It Cosmetics Bye Bye Undereye Illumination Full Coverage Anti-Aging Waterproof Concealer also contains some ingredients often marketed as effective in reducing wrinkles, specifically Magnesium Ascorbyl Phosphate, Ascorbyl Palmitate, Palmitoyl Tripeptide-1, and Palmitoyl Tetrapeptide-7. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards. Therefore, these ingredients do not contribute to the anti-wrinkle rating.
 
Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, can deliver some anti-wrinkle effects through its moisturizing action.
 

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

Rich in skin-protecting antioxidants

We estimate that It Cosmetics Bye Bye Undereye Illumination Full Coverage Anti-Aging Waterproof Concealer is rich (> 3%) in antioxidants, specifically Niacinamide (est. ≈1.0%), Sodium Hyaluronate (est. ≈1.0%), Magnesium Ascorbyl Phosphate (est. ≈0.3%), and others.

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.

Water
Est. %0.3
Function
Origin
WaterThe most used ingredient in skincare. Its concentration defines the product texture: rich creams may have about 50% of water while a light jelly about 90%. Water doesn’t moisturize the skin by itself and is used in skincare as a solvent for other ingredients.
Pentaerythrityl Tetra-di-t-butyl Hydroxyhydrocinnamate
Est. %0.3
Function
Origin
Pentaerythrityl Tetra-di-t-butyl HydroxyhydrocinnamateAn antioxidant that protects vulnerable ingredients from the damage caused by ultraviolet radiation, which can also lead to the generation of damaging free radical species.

N-Hydroxysuccinimide
Est. %0.3
Function
Origin
N-HydroxysuccinimideN-Hydroxysuccinimide is thought to reduce the appearance of dark circles under the eyes. However, more research is needed to confirm if this ingredient is truly effective in this manner.
