This is an interesting product because it contains a natural extract version of real drug active.
This rosy-colored anti-blemish mask feels great during use. Our evaluator thought the aesthetic feel of the product was excellent. She said….”after just 5 minutes I forget that I’m wearing a mask, I love how natural it feels and the glowing skin that follows afterwards is a plus too!” But is there really enough salicylic acid in willow bark extract to do the job? Let’s do the math.
Juara Rose and Willowbark Blemish Free Mask Ingredients
Water/Eau, Kaolin Clay, Capryilic/Capric Triglycerides, Glycerin, Glyceryl Stearate, Cetearyl Alcohol, Ceteareth 20, Cyclopentasiloxane, Red Sandalwood (Pterocarpus santalinus) Powder, White Willow Bark (Salix alba) extract , Rice (Oryza sativa) Starch , Rose Flower (Rosa damascena) Water, Dimethicone, Caprylyl Glycol, Glyceryl Caprylate, Phenylpropanol, Phenoxyethanol, Hydroxyethylcellulose, Vitamin E (Tocopherol) Acetate, Sodium Stearoyl Glutamate, Hydroxyethylacrylate/Sodium Acryloydimethyl Taurate Copolymer, Isohexadecane, Polysorbate 60.
How much willow bark extract is in the product?
As you can see, the willow bark extract (which is a natural source of salicylic acid) is the tenth ingredient. That’s below cetyl alcohol and ceteareth -20 which are used somewhere around 2 to 5 %. So, my best guess is that this product contains about 2% of the extract.
How much salicylic acid is in the extract?
According to Wikipedia and a couple of other references we checked, the amount of salicylic acid in willow bark extract is abourt 10% (it ranges from 1 to 12% depending on the type of willow, the growing season, etc. But let’s assume 10% just for the sake of the discussion.) So, if about 10% of the extract is salicylic acid and there’s about 2% of the extract in the formula, then the formula contains about 0.2% active sal acid at best.
NOTE: After publication of this post the owner of Juara Skincare informed us that the willow bark extract used in this product is standardized to a level of 50% salicylic acid. Therefore, this product ”has an efficacy equivalent of 1% active salicylic acid (not the .2% mentioned in the writeup.)”
How much salicylic acid should a blemish product have?
Many anti-blemish (or anti-acne) products use salicylic acid as an approved active ingredient. The maximum use level is approximately 2% in products like this. So if Juaras’s mask contains about 1.0%, it should be an effective anti-acne product.
