Key actives
Product Summary
"Neutrogena - Collagen Bank 15% Vitamin C Glow Serum" is effective for: Exfoliation, Evens skin tone and Anti-aging
This product could be helpful for: Moisturizing, but its actives are not the most effective or are not well-studied.
Ingredient callouts
- This product contains acids (gluconolactone 3.30% - 5.00%). Their concentration is low, and they will not have a strong exfoliating effect. Instead, they work to support the skin natural acid mantle and to attract water (as humectants). PHAs (gluconolactone) especially are great for improving skin hydration. They might be even able to stimulate the production of skin's natural humectants and support the healthy skin microbiome.
- This product also contains Vitamin C (Ascorbic Acid) 5.30% - 8.00% It can be helpful in stimulating collagen production, neutralizing free radicals in skin and improving pigmentation marks. We recommend to use up this product quickly after opening: Ascorbic Acid degrades fast when it gets in contact with air and light. The moment the product turns orange, it is a sign that a significant share of the vitamin C in it is no longer effective.
- Humectants (hydrolyzed collagen 1.60% - 2.40%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
Anti-aging
What does the product description say?
Collagen Bank 15% Vitamin C Glow Serum
Source: From product name
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains ascorbic acid, gluconolactone.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: epigallocatechin gallate.
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.
A polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals
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
A polyphenol found in tea. This particular compound abbreviated EGCG is the most powerful antioxidant among those extracted from tea (usually green tea). Unfortunately, EGCG is unstable, requires a low pH (below 4) to prevent quick degradation, and does not penetrate the skin very well. This is why the full anti-oxidant effect of EGCG is typically not realized when it is added to topical skincare
Anti-oxidation
This product contains antioxidants (ascorbic 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 - epigallocatechin gallate, gluconolactone also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

Evens skin tone
What does the product description say?
Derm grade, high-potency formula dramatically evens skin tone & leaves skin looking glowy & plumper.
Source: Neutrogena
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: ascorbic acid.
In addition, this product contains gluconolactone. This ingredient (ingredients) might help reduce hyperpigmentation, but the effect, if any, is likely to be small.
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: epigallocatechin gallate.
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.

Exfoliation
What does the product description say?
Formulated with 2% PHA, a breakthrough, derm-discovered exfoliant and hydrator for younger looking skin without the irritation.
Source: Neutrogena
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: gluconolactone.

Moisturizing

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:
hydrolyzed collagen, caprylyl glycol.
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: hydrolyzed collagen, caprylyl glycol.
A typically plant-derived compound that is supposed mimic human collagen. Cannot penetrate the skin barrier so is not particularly useful in skincare products beyond attracting water to the upper layer of the skin
