Wow in think I should try to remember he colors and consistency as well for ingredients. That would make these more useful, wouldn’t it. 🙂 right now, I know most of the ones by what they do and that’s it. I love these posts and they are less conversational which is why there’s probably less comments here but I know we, readers, love them. This makes your blog stand out! Knowledgable beauty. 😀

Janessa, knowing what they do is the most important thing. If you can remember the rest too, that’s a bonus. 🙂

I agree, it’s hard to comment on posts like these. But as long as they’re useful, that’s ok. And thank you! 🙂
