- a reduction in dark spots and fine lines,
- increased brightness, overall smoothness,
- and even marked improvements for skin conditions like psoriasis.
If you've been with us a while, you'll know I (Steve) am a little skeptical with skincare claims, but Vitamin C serums with 10 - 20% L-Ascorbic acid seem to be a pretty safe bet in gaining the above mentioned benefits and in some cases this:
But here's the thing. In my own use, I've noticed that I have be really careful to ensure it doesn't go bad (like storing it in the fridge before use).
You'll know that it goes bad when it turns dark brown.
To offset the volatility, we've added Vitamin E (Tocopherol is the chemical name) & store it in black - opaque - bottles, but we're also considering the addition of ferulic acid, which is supposed to be the gold standard in preservation.
But Ferulic acid SMELLS BAD. Like hotdog water. And we don't think it's a good idea to add fragrances to 'mask' the odor.
So here's my question to you:
Has your etee serum gone bad and if so, how quickly? NOTE: it's fine if it turns yellow to orange, but once it gets dark orange or brown, that means it's not effective.
Would you be willing to accept a hotdog water smell if it meant the serum lasted longer and absorbed better?

I like it the way it is. I leave it in the fridge to keep it fresh, and am happy to do that rather than have to deal with a foul-smelling Vitamin C
Black bottles are not recycled in our area. Do I like hotdogs? Yes but most definitely not on my face. Is it possible to add a non synthetic scent? Rose water or natural oil to cover the unpleasant odor? I love this serum but I do forget it is in the fridge!

Please leave it as it is! 😊
leave it as it is you will be just adding more ingredients to it. If people use it as intended, it should be well used before it goes bad. Adding fragrance is a big no, no, this in itself causes so many skin issues. Leave it in the black opaque bottles
Does the stinky stuff make the user smell bad or does it go away?
I didn’t realize it went bad and I have used it even when brown. Good to know it becomes ineffective when it turns brown. I would like it to last longer, but to refrigerate it would be an extra step to remember (ha, ha) to walk to the kitchen to use it. So I would vote for the hot dog smell with fragrance. I wouldn’t use it if it just had the hot dog water smell. The good smell of your products is a real plus even though they may not be added fragrances.
Thank you for bringing this issue to my attention, otherwise I wouldn’t have known.
Keep the same formula without the bad smelling ingredient.
I don’t think you should add a smelly preservative and then mask it with more fragrance.
