UVB rays are a type of light emitted from the sun. UVB rays are known to cause sunburn, skin cancer, and accelerate skin aging. UVB rays are defined based on the length of their wave. UVB light has the wavelength between 290 and 320 nanometers.

UVB waves are shorter than the UVA ones. This is why they cannot penetrate human skin as deep as the UVA light can. At the same time, UVB light has more energy in it, meaning that it can cause a more direct damage to the skin cells (and their DNA more specifically).

Some of the popular UVB filters used in sunscreen include:

Sun radiates different types of light. Some of it falls into the so called ultraviolet range (UV light). When you hear terms "sun protection" and "sunscreen", what is usually meant is protection from the UV light.

The effect of light on the skin depends on the length of its wave. The shorter the wave, the more energy it has, but also, the more "shallow" it is in terms of how deep it can penetrate into our skin. The longer the wave, the less powerful it is in terms of energy, but the deeper it can penetrate into the skin.

Depending on the wavelength, we differentiate ultraviolet light type A (UVA), ultraviolet light type B (UVB), and ultraviolet light type C (UVC). UVC rays are the shortest, most powerful, and least penetrating, while the UVA rays are the least powerful, but the most penetrating among the three types. Luckily, the ozone layer in the atmosphere absorbs the UVC rays so they don't reach the Earth surface and don't get a chance to harm our skin.

I discovered this brand - London Grant  (handcrafted in Atlanta) - looking specifically for indie brands founded by people of color. I'm so grateful I've discovered it - beyond a great story, I just love the way they approach skincare and formulations.

In a nutshell, it's the best of the two worlds that rarely meet in skincare today: natural + fragrance free. And I personally as a skincare minimalist dig the name of their product line: The Minimalist Collection ❤️.

The brands founder, Tiffany Staten, started the company in 2016 in her small Atlanta kitchen. The brand's goal is to create products that are effective and safe for the whole family. And I think that many of the products indeed would work even for children.

Hello! Let me introduce myself: I’m Chloé and I work with What’s In my Jar 👋🏼I am about to graduate with a degree in Biomedical Sciences, but my focus was Neuroscience, so I never particularly focused on skincare (until I got so obsessed with it that I decided to do my thesis on the microbiome and skin ageing this year🔬)

Like many of you, I have an acne journey. It started 3 years ago out of nowhere when I started university. I didn’t know why my skin was acting up and I didn’t know who to turn to because I thought my condition wasn’t severe enough to see a doctor. I had a preconception that acne was only related to poor hygiene which led me to over-exfoliate, pick at my skin, grow increasingly paranoid about each new blackhead or pimple, and be very hard on myself. It took me 2 years to go see a dermatologist...when my confidence was at an all time low. And it took me an extra year to finally feel equipped to take care of my acne on my own - phew, took a while!

Fastforward to today, there are three main things I wish I would’ve known:

We are seeing a surge of searches for this product on our website, and I thought I'd type a quick formula review.

Great things about this product:

  • No fragrance

  • Lovely packaging

  • Good basic moisturizing formula with humectants (sodium hyaluronate) and emollients (silicones mostly do the job, with addition of olive oil and tiny amounts of avocado oil).

“I’m only in my 20s so I don’t need to think about skin aging”. There is no miraculous switch that turns on skin aging the moment you hit 30 - you age your whole life from the day you were born. The appearance of wrinkles shouldn’t be the trigger for you to start caring about your skin💪

Skin aging is more than just a cosmetic problem, but people’s endless quest towards the fountain of youth has definitely fuelled research & innovation in the field ⛲️ With life expectancies on the rise, the care of aging skin must also include how skin disorders affect quality of life, not just aesthetics. Most people over 65, in fact, have at least one skin disorder, and many have two or more. Although rarely fatal, they deserve attention ⚠️ 

It is commonly thought that aging is mainly predetermined by your genes - “my parents have deep wrinkles, therefore I am doomed to have the same”. However, research suggests that most of the effects of skin aging are caused by extrinsic factors (sun exposure, pollution, etc), and only 3% of aging factors have intrinsic background (genetics, etc)❗️

That’s what we are so often advised to do.  Beat it back, stay ahead of it.  Be consistent and stick with it – it’s going to be a while.  Yet, “a while” became a consistent part of life for 15 years.

It's estimated that about a third of all cosmetics-related skin reactions are related to fragrances (natural or synthetic).

But what exactly do the fragrances do to harm the skin?

The disappointing answer is: the science doesn’t fully understand why. It might have something to do with the fact that all fragrances used in skincare are volatile organic compounds (VOCs). But this chemical “family” is very broad and includes many different chemicals ranging from compounds that our own skin emits, to those causing strawberries or a face cream to smell delicious to road traffic pollutants.

Cannabis plant is famous (and infamous) because it contains a specific type of chemical compounds called phytocannabinoids. There are over 100 different types of them.

These compounds are similar in their chemical structure and biological effect to endocannabinoids, the chemicals that human body produces naturally. These chemicals can bind to special receptors in our cells, “instructing” the cell to behave in a certain way. For example, to change its inflammatory response or grow slower or faster. Our skin cells have the cannabinoid receptors, and this is why cannabis is more than just a trend in skincare.

Not all parts of the hemp plant contain cannabinoids. For example, hemp seeds contain, if any, only a small amount of cannabinoids. This means that if you see a product with a cannabis seed extract in it, you should not expect any cannabinoid-related effects.

Surely we all heard that sun exposure (UV light) is a driver of skin ageing and an effective skincare routine should include a daily sunscreen. But how exactly can something as nice, warm and mood-boosting as sunlight cause the harm? What does UV radiation actually do to our skin that causes wrinkles and elasticity loss?

The main mechanism of damage is the following. UV light activates cell receptors in the epidermis (upper) and dermis (deeper layer) of our skin. This activation happens within 15 min of sun exposure and lasts for at least 2 hours after it.

The activated receptors start accepting distress signals from outside of the cells. It happens within 30 min of sun exposure and lasts for full 24 hours. The signals activate enzymes within the cells, and the enzymes, in turn, start synthesis of special proteins with the function of "cleaning up" a site of skin wound. The "cleaning up" involves destruction of collagen fibers in the skin.
