Product Summary
Based on the ingredients included, "NATURE REPUBLIC - Africa Bird Homme All in One Fresh Controller" works well for moisturizing the skin. As we expect from a proper moisturizer, the formula includes a combo of effective humectants and emollients. These are the two different types of ingredients that are essential for improving the skin hydration and supporting a healthy skin barrier. Acetyl glucosamine, algae extract, betaine, glycerin and sodium hyaluronate in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Emollients in this formulation (ceramide np, algae extract, cholesterol, dimethicone and cetyl alcohol) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.
Ingredient callouts
- We particularly like that there is a good concentration of Niacinamide (2.40% - 2.90%) in this moisturizer. Niacinamide is a well-studied multi-tasking active. It is a great ingredient to have in a moisturizer. 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 help improve the skin tone, reducing pigmentation marks.
- Another benefit is that this moisturizer contain ceramides (ceramide np 0.30% - 0.50%). Ceramides are an important part of our natural skin barrier. The Ceramides used in skincare are synthetic or come from plants. They help soften the skin and can help "fill the gaps" in the skin barrier, keeping the skin hydrated and resilient for longer.
- This moisturizer also contains Peptides (palmitoyl pentapeptide-4 0.20% - 0.35%). 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 they are 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.
- Adenosine 0.25% - 0.45%. It is a chemical present inside our skin cells. A clinical trial confirmed that topical application of Adenosine in a low concentration can reduce dynamic wrinkles (these are the wrinkles that appear with age in a places where our mimic is the most active, for example, in the corners of the eyes or on the forehead).
Irritation risk
This formulation includes some common irritants, including ingredients that do not provide a benefit for the skin. We assess the overall irritancy of this moisturizer to be high. For a detailed overview of all potential irritants: click here

Anti-aging
What does the product description say?
The product contains niacinamide to brighten the skin tone and African red tea leaf extract with pore-tightening and anti-aging properties.
Source: Yesstyle
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains acetyl glucosamine, adenosine, niacinamide.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: folic acid, palmitoyl pentapeptide-4.
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
Might help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)
An effective moisturizing ingredient that also has been shown to be effective in evening out the skin tone and reducing hyperpigmentation. It can help somewhat reduce wrinkles in skin
A type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles
Can help stimulate collagen production in skin. While available studies are promising, more research is needed to confirm the efficacy in skin
Plant extract that helps the skin to attract water and make it more smooth for touch. Also shows promise of anti-aging properties, but research is not extensive yet
Might be helpful against blemishes, work as an anti-oxidant, reduce inflammation and improve skin's ability to hold on to moisture, but more research is needed to confirm its effectiveness when applied topically to human skin
Traditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin
Anti-blemish
This product can help reduce breakouts and clogged pores because it contains the following ingredient: niacinamide. This ingredient is used for treating acne and can have a noticeable effect.
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

Evens skin tone
What does the product description say?
The product contains niacinamide to brighten the skin tone and African red tea leaf extract with pore-tightening and anti-aging properties.
Source: Yesstyle
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: acetyl glucosamine, 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: glycyrrhiza glabra root extract.
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.
An effective moisturizing ingredient that also has been shown to be effective in evening out the skin tone and reducing hyperpigmentation. It can help somewhat reduce wrinkles in skin
Is proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles.

A plant extract that can help lighten the skin and calm down inflammation. Might be helpful in neutralizing free radicals
Moisturizing
What does the product description say?
Tripling as a toner, emulsion and essence for men, this moisturizer is packed with African baobab extract to help strengthen the skin barrier and retain moisture.
Source: Yesstyle
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:
algae extract, betaine.
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: dimethicone, algae extract.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl glucosamine, ceramide np, niacinamide, palmitoyl pentapeptide-4
An effective moisturizing ingredient that also has been shown to be effective in evening out the skin tone and reducing hyperpigmentation. It can help somewhat reduce wrinkles in skin
