779: Picking Lip Filler To Fit Your Aesthetic
Happy Friday, Beauty Byters!
In this week’s Five Minute Friday, I am joined by my patient Samantha who is the co-founder of Links Financial! We talk about starting small with filler because you want people to take you seriously, to pick lips that fit your branding- but to not get tied to a stereotype. Samantha believes that looking more powerful and attractive can make her feel even more confident in the boardroom, and at the end of the day who doesn't appreciate a pretty business woman. However, I believe is a fine line between sexy and porn star and lately I have been talking people down from getting too much lip filler. Listen in to hear our conversation about lip filler! I love informing my Beauty Byters with new information! Have a question or something you’d like covered on the podcast? Send me a DM or email info@beautybydrkay.com!
