New name, same content - our Clarifying Serum is now called Purifying Serum!

This light and oil-free gel-serum is an anti-microbial and sebum-regulating power house that purifies sensitive and problem skin and fights pimples and inflammation - without drying. It also contains no preservatives, so is extra gentle on sensitive skin.

We put in anti-bacterial, plant-based xylitol sugar and our favourite multi-tasking ectoin for a healthy skin barrier and to prevent dryness. Swedish algae-derived silica absorbs impurities from skin while adding hydration, and anti-inflammatory zinc and copper PCA balance out sebum production. Great for alleviating symptoms of acne, seborrhea and malassezia-induced acne (fungal) - the gentle way.

Formulated for sensitive & problem skin. Fragrance-free. Vegan & natural ingredients. Developed in our own Helsinki lab & made in Finland.

Ingredients (INCI)

Aqua, propanediol, ectoin, zinc pca, xanthan gum, acacia senegal gum, xylitol, copper pca, silica, citric acid. More info

How to use & tips

  1. With sweeping motions apply sparingly to cleansed skin before oils and creams, before or after any toner. Can be used locally or on the entire face. Applying too much will cause product to pill.
  • Tip 1: Use under or mixed with our Face Cream for the ultimate treat + care routine for acne-prone and congested skin.
  • Tip 2: Excellent for alleviating symptoms of acne, seborrhea and malassezia-induced acne (fungal).

Why it works for sensitive & problem skin

•Contains only ten ingredients.

•Contains no added fragrance (and no essential oils or floral waters) and no alcohol.

•pH is around 5.5 (healthy skin's own pH is slightly acidic, between 4.8 and 5.5).

•Contains no preservatives - because of the high level of anti-microbials in the product, it’s entirely self-preserving

•Non-drying base – the Clarifying Serum the same hydrating and conditioning plant-based glycerine and propanediol combo we use in the Calming Serum.

•Algae-derived silica absorbs impurities and bacteria from skin while adding hydration in a manner similar to hyaluronic acid

•Ectoin is a true multi-tasker: its benefits include long-term hydration, diminished skin roughness, skin barrier repair and anti-inflammatory and anti-irritant properties

•Zinc PCA regulates sebum production, reinforces the skin's barrier function, soothes skin and has anti-acne properties

•Copper PCA has antimicrobial and astringent properties and regulates sebum and fights impurities

•Xylitol is antibacterial, hydrates and fights bacterial film on skin.

The Clarifying Serum has been rigorously tested by our founder Kristina and chemist Jaana, both of whom have a long history of sensitive and problem skin. The Clarifying Serum was also put through a lengthy trial with our sensitive and problem-skinned customers. 

•Allergy-labelled by the Finnish Allergy, Skin and Asthma Federation.

Solvent. Water. The main vehicle for our Clarifying Serum.


Solvent and humectant. Apart from being an excellent, non-irritating solvent, the glycol propanediol has excellent hydrating and preservative boosting properties. The one we use is made from fermentation of glucose, from corn.


Skin conditioning. Ectoin is a powerful, small, multi-tasking and natural stress-protection molecule, a so-called extremolyte. From a chemical point of view, it is a cyclic amino acid derivate. Extremolytes protect extremophilic microorganisms and plants from the extreme conditions of their habitats like salt lakes, hot springs, permanent ice or deserts. The properties of ectoin have been proven by various in-vivo studies: its benefits include long-term moisturisation, diminished skin roughness, skin barrier repair and anti-inflammatory and anti-irritant properties. We get ours from a lovely company in Germany, where it is produced through biotechnological fermentation from a specific, non-GMO strain of the halophilic bacteria Halomonas elongata.


Humectant and skin conditioning. Zinc PCA regulates sebum production, reinforces the skin's barrier function and together with Copper PCA fights pimples. The zinc salt of L-Pyrrolidone Carboxylic acid or L-PCA. L-PCA is obtained by the cyclization of L-glutamic acid, amino-acid from vegetal origin.


Thickening, gel forming and stabilising. A natural and commonly used mainly thickener and gelling agent in cosmetics, xanthan gum is a polysaccharide produced through bacterial fermentation of pure culture Xanthomonas Campestris with protein and carbohydrate sources, in this case from soy or corn. Together with acacia senegal gum, it makes up the gel base for our Clarifying Serum.


Film forming. Also known as gum arabic, acacia gum is a natural gum consisting of the hardened sap of two species of the acacia tree. In cosmetics, acacia gum is used for it's ability to create less stringy, or slimy and sticky, gels. The acacia gum we use is ethically and sustainably handpicked in Africa, and is a 100% renewable raw material.


Humectant and skin conditioning. Xylitol is a sugar alcohol and moisturises and conditions skin, whilst possessing anti-bacterial properties. There is some interesting research that suggests xylitol has the ability to inhibit bacterial biofilm on skin, which in turn may be the cause of many skin issues. The one we use is made in Finland from European hardwood.


Humectant and skin conditioning. Copper PCA is also antimicrobial, astringent, sebum regulating and fights impurities. The copper salt of L-Pyrrolidone Carboxylic acid or L-PCA is obtained by the cyclization of L-glutamic acid, amino-acid from vegetal origin. Gives the product a slight blueish colour.


Absorbent. Mesoporous silica, trade named Algica, from Swedish algae, that absorbs impurities and bacteria. Improves skin's moisture retention by its ability to bind water, in a manner similar to hyaluronic acid.


Buffering agent. Citric acid is a commonly used buffering, i.e. pH adjusting, agent in cosmetics. The appropriate pH is vital for a product's preservative system to work, but also to guarantee its skin-friendliness. Citric acid is made through bacterial fermentation and shifts the pH of the product into the acidic range. This is closer to the natural pH of the skin, which may range from 4 to 7, but is usually thought to be between 5 and 6, with recent studies, however, indicating it to be below 5.

Clarifying Serum

Tämä on todella mahtava. Olen käyttänyt jo pitkään. Kirkastaa, puhdistaa ja hoitaa ihoa. Rasvoittuminen ja epäpuhtaudet pysyvät kurissa.


Toimiva tuote herkälle akneiholleni.

Miriam Costi
Best solution ever

Works fine against impurities and stress eruptions without drying out sensitive and dry skin. I always order it back again. Just a shame it got more expensive.

Kevyt seerumi

Ihoni tulehdukset ovat hieman rauhoittuneet tuotteen aloituksen jälkeen (noin 3 vk).
Plussaa kevyestä koostumuksesta, sopii meikinkin alle (yksi painallus riittää).

Tea M.
Uusi suosikki on löytynyt!

Ihanan kevyt ja raikastavan tunteen jättävä seerumi! Muutaman viikon käytön jälkeen huomaan ihoni kunnon parantuneen huomattavasti ja näpyt pysyvät aisoissa.
