Product Summary
"Algenist - Green Microalgae Retinol + Regenerating Serum" is effective for: Exfoliation, Moisturizing, Evens skin tone, Anti-aging and Anti-blemish
Ingredient callouts
- This product contains acids (gluconolactone 0.45% - 1.10%, glycolic acid 1.00% - 1.50% and lactic acid 1.20% - 1.80%). 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 contains an effective form of Retinoids (vitamin A): retinol 2.00% - 3.00%. 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.
- Salicylic acid (1.00% - 1.60%). 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.
- Panthenol (pro-vitamin B5) at about 0.35% - 0.80% concentration. In this concentration, Panthenol works effectively to improve the skin barrier and reduce inflammation.
- Humectants (sodium pca 0.30% - 0.75%, panthenol 0.35% - 0.80%, parachlorella beijerinckii exopolysaccharides 1.70% - 2.50% and glycerin 3.70% - 5.60%). 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?
This high-performance serum combines the dual action of time-released vegan retinol and the retinoid-like benefits from Fermented Green Microalgae to diminish the appearance of deep lines and wrinkles, with minimal irritation.
Source: Algenist
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains retinol, glycolic acid.
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.
An alpha-hydroxy acid (AHA) that helps to remove the dead skin cells on the surface of the skin reveling a more even, smoother complexation. It is also able to stimulate collagen production with long-term use. Could help to reduce pore congestion. It can be irritating to the skin. Apply sunscreen daily if using products with glycolic acid
Two steps removed from the active form of vitamin A - retinoic acid. Once converted to the retinoic acid in the skin, retinol 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. It can, however, be quite irritating
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
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 microbiome)
Pure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself
Anti-blemish

An active component of chamomile plant that historically has been used to calm down irritated skin. A recent study shows that bisabolol indeed can have some anti-inflammatory effect on skin, even though conclusive data is lacking. Bisabolol has a sweet floral scent and can be added to products for its aromatic properties
Evens skin tone
What does the product description say?
A blend of AHA, BHA, and PHA’s also boosts the exfoliation of skin’s surface layers to reveal smoother, more even skin texture and tone.
Source: Algenist
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: retinol.
In addition, this product contains glycolic acid, salicylic acid. 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 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: glycolic acid, retinol, salicylic acid.

Moisturizing
What does the product description say?
Skin’s texture is improved by promoting accelerated skin cell turnover.
Source: Algenist
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, parachlorella beijerinckii exopolysaccharides.
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: copernicia cerifera wax, helianthus annuus seed oil.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol
Helps to soften the upper layer of the skin and create a nice product consistency
Helps attract water to the upper layer of the skin and can help improve skin barrier function
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
A great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function
Compounds extracted from green algae that could help neutralize free radicals, but evidence of effectiveness in skincare products (topical applicaiton) is missing. Helps moisturize the skin by attracting water to its upper layer
Naturally present in skin and helps to attract water to its upper layer
Helps create a non-greasy finish on the skin
