Not been very active here 🦋 or 🐦 lately—it’s tough keeping up with both and even more to rebuilt the community.

For new folks 👋👋: I’m an MSCA fellow studying IgE plasma cells

This is a disaster if the EU doesn't follow up by doubling the budget 😬🧪

As a science girlie, I hate buying skincare. Rarely any actual data.

Active ingredient concentrations? “Oh, you’d never guess.”
Clinically proven to be 200% amazing. Can I see the study? “Well, we asked 20 people and they said it’s fab ✨”
