  • L-ASCORBIC ACID AND SALICYLIC ACID IN VITAMIN C SERUM

    Hi, 

    Please does anyone know if it is safe to use salicylic acid and L- acorbic acid in the same formula. Ph is quite similar to work but is  there something else that could explain why these two are not normally added in the same product. Or is it that more profitable to sell two products than one combined?

    This one has 0.5% SA.  I think the answer is two-fold:
    -1-  Each ingredient is difficult to work with, for different reasons, so using both in one formulation further complicates things.
    -2-  What % of each would you be using?  If you were planning on say >10% ascorbic acid, then your product would be marketed for one particular function (anti-aging, antioxidant, etc.), and if you’re planning on a full 2% SA, then your product is most likely wanting to boast anti-blemish effects.  It might not be an easy “sell” to offer all of this in one item; if you look at the marketplace, consumers are usually asked to choose one or the other in a product:  antioxidant/anti-aging or anti-acne.  Stated otherwise, I cannot remember the last time I saw a product being promoted as both anti-aging and anti-acne.  What you are proposing would not be a bad idea, it would just be a question of how you would want to market the product.

    The ascorbic acid product in the market often direct to use only a few drops one time. Salicylic acid - enough to soak a cotton pad usually.

    Thank you yes you are right it would be difficult to promote 2 in 1 product. But I just thought if you are suffering from acne both would be great for skin and more time efficient. Also not sure why Vitamin c is just few drops being advertised, as acorbic acid oxidises so quickly you should use it as quickly as possible. I am using at home and it is  not a big issue to put more actually i think my skin looks better from bigger quantity. Thank you both for your help.
