I don’t have much to say about the process of making this comic, so I’ll just keep talking about cosmetics.
Beware claims. Cosmetics companies are not kindly doctors trying to help you with your hideously abnormal complexion/eyelashes/lips. They’re salesmen trying to turn a profit. And they will say next to anything they think you want to hear to get you to give them your money for this promised philosopher’s stone of beauty. Whenever advertisements throw out numbers or percentages, look a little harder and you’ll find holes in their claims. Wouldn’t want to get caught in a false advertising lawsuit, would they?
