A new study suggests that the skin microbiome may be linked to premature skin aging. Here’s a quick summary.

Sixty-five women aged 40–50 were split into two groups (prematurely aging skin and delayed aging skin)⚡
Basleine microbiome analysis revealed significant differences. The prematurely aged group had higher levels of the bacteria Acinetobacter, increased diversity of microbes, and a more fragile microbial community network🔬
In the study, the prematurely aged group was given a skincare product containing retinyl propionate twice daily for four weeks📅
The retinyl propionate intervention significantly improved key age-related skin features (brightness, elasticity, hydration, and barrier function)🛡️
At the end of four weeks, treatment with retinyl propionate also shifted the microbiome of the prematurely aged group to be similar to that of individuals with delayed aging✨
This is one of the first studies to compare the skin microbiome of people with visibly different aging profiles but the same chronological age📚

Instagram is rolling out new features that allow users to draw directly on their direct message screens Here’s a quick summary:

Instagram has officially announced the broader launch of new options to draw on and place stickers within the Direct Message (DM) screen📣
Users can access the "Draw" option by tapping the "+" menu icon next to the message composer in a chat🎨
Users can also place various stickers within the DM frame to further customize their discussions🩷
The drawings and stickers are temporary and will disappear from view as the conversation continues✨
The new options are part of Instagram's effort to add more messaging features to spark engagement, as DM usage is increasing🚀
"Sends" (Direct Messages) are now a greater focus for Instagram's algorithmic amplification because they are considered more meaningful than "likes✅
