Product Summary
"Kester Black - Super Retinal Vitamin A Serum" is effective for: Moisturizing, Anti-aging, Evens skin tone and Anti-blemish
Ingredient callouts
- A good concentration of Niacinamide (5.00% - 7.50%). Niacinamide is a well-studied multi-tasking active. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and improve the skin tone, reducing pigmentation marks.
- This product contains an effective form of Retinoids (vitamin A): retinal 0.40% - 0.90%. Retinoids are potent multitasking actives. They work to improve and prevent early signs of aging, reduce hyperpigmentation (age spots and post-acne marks), and prevent inflamed blemishes and clogged pores. The downside of Retinoids is that they can be irritating. If you are not already using a Retinoid in your routine, it is best to start slowly and apply the Retinoid product only a few times per week. If your skin tolerates it well, you can gradually increase the frequency to daily.
- Peptides (acetyl hexapeptide-8 0.45% - 1.05%, palmitoyl tripeptide-1 0.55% - 1.30%, palmitoyl tetrapeptide-7 0.90% - 1.35% and copper tripeptide-1 1.00% - 1.50%). Peptides are a very big group of ingredients. They all consist of a different combination of aminoacids. Our skin produces Peptides naturally. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The scientists are still studying how effective the topical application of Peptides is, but it is very likely that theynare helpful. Peptides might be able to support skin barrier restoration and even have an anti-aging benefit. At the very least, they certainly help attract water to the skin and support the hydration in this way.
- Salicylic acid (0.40% - 0.90%). This is an oil-soluble exfoliating acid. Because of this property, it can work inside pores and help reduce the congestion. It has an anti-inflammatory effect and is used to treat acne. Because it is a quite strong exfoliator, be careful with using this product too often: it could result in over-exfoliation.
- Humectants (acetyl hexapeptide-8 0.45% - 1.05% and glycerin 3.50% - 5.30%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains retinal, niacinamide.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: acetyl hexapeptide-8, copper tripeptide-1, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1.
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.
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. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production
One step removed from the biologically active in skin form of vitamin A. Once converted to the retinoic acid in the skin, retinal is proven to be effective against all signs of aging. It improves skin cell turnover, helps fight blemishes and clogged pores, can regulate excess oil production and even skin tone. Concentrations of 0.05% and 0.1% are shown to be effective. It can, however, be irritating
A type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles
A naturally occurring peptide. One of the most studied peptides in dermatology. It is sometimes abbreviated GHK-Cu. Belongs to the class of carrier peptides. It stimulates both synthesis and breakdown of collagen in skin. It is released in skin wounds and inflammation to support healing. It accelerates wound-healing of the skin and can stimulate hair growth. There are preliminary studies that confirm that copper tripeptide can help support collagen production reducing fine lines and wrinkles and decrease inflammation in skin.

Used for skin exfoliation. It has an anti-inflammatory and anti-bacterial effect, helps to unclog pores, prevent blemishes and speed up healing of the existing ones. Sometimes referred to as a BHA (beta-hydroxy acid)
Evens skin tone
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: retinal.
In addition, this product contains niacinamide. This ingredient (ingredients) might help reduce hyperpigmentation, but the effect, if any, is likely to be small.
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.

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:
glycerin, butylene 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: palmitoyl tetrapeptide-7, palmitoyl tripeptide-1.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, copper tripeptide-1, niacinamide, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1

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.
