You Are What You Eat and Drink
I don't believe one blowout meal or bottle of wine is going to do too much damage long-term, but no woman gets to her 30s without recognising what too many days and nights of excess can do to her skin. I know that what I eat affects how I look. I've seen how dull my skin looks after a big weekend of partying compared to a week of clean eating.
So, if I notice a change in my skin or hair, I think about what I've been eating and drinking before I start blaming products. And while I will never turn down a glass of wine or a slice of cake for fear of what it'll do to my skin, I am now much more aware of how nutrition and hydration affect the body in more ways than just weight.
