Skin Conditioning, Solvent

1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse. 

It is a:

  • Humectant, drawing moisture into the skin
  • Emollient, helping to soften skin
  • Solvent, dispersing and stabilizing formulas
  • Preservative booster, enhancing the antimicrobial activity of other preservatives 
Emulsifying

Polysorbate 20 is made by combining ethoxylation of sorbitan, ethylene oxide, and lauric acid. It is a mild cleansing agent, surfactant, and emulsifier.

As a surfactant, it helps collect dirt and oils for washing. Emulsifiers prevent oils and water from separating.

Polysorbate 20 also adds scent to a product. Since it is made using sorbitol, it has a sweet scent. Sorbitol can also be found in fruits such as apples and peaches.

The lauric acid used to create Polysorbate 20 is often derived from coconuts.

Polysorbate 20 may not be fungal acne safe.

UPDATE: their homepage actually says that it’s not retinol 2.5% but only 0.13%. That low percentage does nothing for your skin 😂 For me it’s misleading advertising and I have read they do that a lot with their products. Hence I m not buying anything more from them. Also in Germany a product that contains over 1% Retinol is considered medical care and usually needs prescription (EU regulations). So Show more

This was genuinely one of those products that I'm not sure if I noticed any results. Aside from the uncertainty of this product and the ingredients. I also did not enjoy the consistency of this serum. It felt as if it never fully absorbed and made my skin feel rather oily. Not sure about the other products from this brand, but I feel unlikely to repurchase this.

The best exfoliator i ever tried. I think it's the best choice for those who has stubborn blackheads, because it literally melts them away. People with sensitive skin should be cautious, because it's an intense product and maybe too harsh for sensitive and dry skin types. I would highly recommend to use a deeply hydrating mask and restore skin's barrier after the procedure, because as I said Show more

Very good but beware it’s very strong. It says use once or twice a week but I would recommend once very 2 or three weeks. If it’s too strong for you, use the Glycerin Acid Toner 7%. After that don’t put any toner. Pair it up with Hyaluronic acid of your choice and a very moisturizing cream in the night time and you’re all set :)
