That it’s more work than you could ever anticipate. When a lot of people start a brand, I think they go into it with the mindset that it will purely be an artistic endeavor of self-expression, but there are so many other logistical moving parts that go into building a brand that are far from glamorous and continually challenging.
It was about learning the language of science. Each compound has a specific name assigned to it, so when you read a product ingredient it quite literally tells you its exact composition. As I began formulating, I was able to understand this language or scientific code, and it ultimately helped me to create better makeup products.
When developing products, we need to achieve two things: the finish has to look really alive, and we only use skincare actives that have a lot of data and research behind them. Some products are also inspired by the things going on in my life. Glow I.V. Vitamin-Infused Skin Enhancer was born from my love of vitamin drips. Whenever I’m stressed or need self-care, my go-to treatment is an IV drip. I started to notice how healthy and glowing my skin looked and decided to bottle it.
Your ultimate, favorite-of-all-time beauty product?
Concealer is my top beauty product of all time. It’s so versatile–I can do my entire complexion look with just concealer if I needed.

Yes! It was Givenchy’s Prisme Libre pressed powder that I got when I was 11. I just remember thinking it was the most magical and beautiful thing I had ever seen.
For morning, it’s the Kosas Plump + Juicy Vegan Collagen Spray-On Serum. It has completely changed my skin and has all these powerful skincare actives that soothe, smooth, plump, and hydrate my skin without over-moisturizing.
The most important part of my nighttime routine is double cleansing. I have to make sure I’m removing all of the makeup and residue off my face before I get in bed. I use Emma Lewisham Cleansing Oil and Circumference Cleansing Gel and love it both!
Overlining my lips and brows to bring some drama to my features and really make them pop. I could only do my lips and brows and nothing else, and I immediately look and feel put together. Also, super important—always fill in your brows in the direction of hair growth!
