Oxy Skin

Oxy Skin at a glance

Oxy Skin is a postbiotic active from Switzerland, also known as OXY 229 PF. Its INCI is Saccharomyces Lysate, Valine, Threonine, Glutamic Acid, Glycine, Disodium Succinate. It is a yellowish liquid used at 1 to 5% of the finished product. The supplier's own testing was done at 3%. It is added below 40 °C, dissolved in water or in the active phase.

The postbiotic idea

The skin is home to a community of microorganisms, its microflora. A balanced microflora is part of healthy looking, comfortable skin. Cosmetic care for the microflora started with prebiotics, which feed good microbes, and probiotics, which are live or inactivated microbes. Postbiotics are the newest step. They are made from microorganisms, often as lysates, the content of broken cells, and they bring the useful compounds of the microbes without any live bacteria. This makes them easy to formulate and preserve. Oxy Skin belongs to this new wave.

What is inside

The base is a lysate of Saccharomyces, the yeast family used in baking and brewing. It is combined with four amino acids: valine, threonine, glutamic acid and glycine, which are building blocks of skin proteins and part of the natural moisturizing factor. Disodium succinate, a salt of succinic acid, completes the blend. Succinic acid is a natural part of the energy cycle of cells, which fits the oxygen and vitality story in the name.

What the supplier reports

In its testing at 3%, the supplier reports less dull looking skin, less visible redness and better cell respiration and vitality. In cosmetic terms, products with Oxy Skin help dull, tired skin look alive again, make the skin feel smoother and give a radiant look that appears healthier and younger.

How to formulate

Dissolve Oxy Skin in water or in the active phase and add it to the formula below 40 °C. Keep the finished product at a skin friendly pH of about 5 to 6. It suits serums, essences, creams and masks. For a radiance serum, combine it with niacinamide and with a prebiotic such as inulin for a complete biotic story. More actives are listed in the cosmetic actives section.

Product ideas

The supplier lists products with a focus on fresh, glowing skin, deep leave-on cosmetic formulas and postbiotic care. Typical concepts are glow serums, morning essences, oxygen style day creams, overnight leave-on cosmetic use masks and microflora friendly moisturizers.

Sample recipe: postbiotic glow serum, 100 g

Distilled water 84.50 g, Oxy Skin 3.00 g, niacinamide 3.00 g, glycerin 3.00 g, propanediol 3.00 g, inulin 1.00 g, hydroxyethylcellulose 0.70 g, panthenol 0.50 g, preservative 1.00 g, citric acid solution 0.30 g. Dissolve niacinamide and inulin in the water, disperse the cellulose, add glycerin, propanediol and panthenol, cool below 40 °C, add Oxy Skin and the preservative, and adjust to about pH 5.5.

Biotic layering

Brands often build a full biotic line: a cleanser with prebiotics, a serum with a postbiotic and a moisturizer with both. This gives a clear story on the pack and lets each product do one job well.

Preservation

Postbiotics contain no live microbes, so they do not need special handling, but like all natural lysates they need a reliable preservative system.

Testing claims

Radiance and dullness claims are best supported with standard photos and gloss or color readings before and after four weeks, together with a consumer questionnaire on freshness and smoothness.

Claims

Speak of fresh, radiant, smoother looking skin, less dull and tired looking skin and support for a balanced skin microflora.

Storage

Store in a dry, dark place in a closed container. A certificate of analysis comes with every lot.
