Skincare Articles

Hello! I am Maria from the WIMJ team. I’ll share my skincare journey with you. I grew up in Ukraine. I have an older sister, and my mom has always been interested in skincare, so I grew us watching these two beautiful women do DIY face masks. The thing is many skincare products were not available in Ukraine at that time, or they just couldn’t afford it. This is where my love for skincare comes from.

I also have a little bit of hate towards some skincare:). When I approached my teenage years, menthol-enriched anti-skin acne washes were, unfortunately, already in abundance. And an older friend told me that “blackheads appear because the skin is dirty”.  So yeah, I was off to a great start in facing the hormonal rollercoaster of adolescence:).

The uppermost layer of the skin resembles a brick wall: already dead cells serve as bricks, and skin lipids together with moisture-loving compounds "glue" them together like mortar.

This “brick wall” is called stratum corneum and it is responsible for the skin’s barrier function. In other words, its purpose is not to let things into the deeper, living layers of the skin and the rest of our body. This also means that the products we apply to the skin are most likely to stay on the surface never making it through the “brick wall”.Some products can penetrate deeper though. In most cases, the penetration happens through the “mortar”: the lipids between the dead cell “bricks”. The route is long: our skin’s “brick wall” is 10-15 cell layers thick, and the larger the bricks are, the longer way the compounds need to travel around them through the lipid “mortar”. This route is also only accessible to lipophilic molecules (like retinol) and not water-soluble ones (like Vitamin C). Water soluble molecules can still fight their way through - but they need to penetrate the “bricks” themselves.Ingredients can penetrate deeper into the skin through hair follicles and pores: they can offer a "short cut" for reaching skin's dermis.

As skin ages, its look might be changing. But its ability to serve as an excellent barrier against environmental factors remains strong.

This is a skin science post of ultimate positivity: we don’t need to worry about aging of the upper most layer of our skin, the stratum corneum. Based on the studies conducted to date, it appears that the skin’s barrier function doesn’t age, or, at least, there tend to be no significant differences in the barrier function between people aged 20-25 and those who can boast with 30-40 more years of life experience.

Our bodies are made of chemicals, so is our skin. Plant extracts and DIY kitchen cabinet masks are made of complex chemical compounds, too.

In fact, their chemical composition is more complex than the man-made skincare ingredients. In other words, with a lab-produced ingredient, you are getting one pure well-known substance.
