How To: Which blade do I choose for my razor?
Shaving with a single-blade razor is – especially the first time – a new experience. The razor feels different (because it’s heavier), and you have to choose and replace the razor blades yourself.
It takes a little getting used to, but before you know it, you’ll be comfortable with your new way of shaving.

And not only that, you’ll never want to do it any other way.
In the YIONN shop, you can choose from two types of razor blades for your single-blade razor: standard blades (sharpness 2) and blades for coarse and dense hair growth (sharpness 4).
What’s the difference, and which one is most suitable for you?
I’ll explain it in this article.
The Sharpness of the Razor Blade
When choosing a razor blade for your razor, it’s very important to pay attention to the sharpness of the blade.
Razor blades are available in 5 different sharpness levels: from sharpness 1 to sharpness 5. The higher the number, the sharper the blade.
1: very mild sharp
2: mild sharp
3: medium sharp
4: very sharp
5: ultra sharp
A razor with a higher sharpness isn’t necessarily better than a razor with lower sharpness. What really matters is which sharpness suits your skin and hair type.

Which Sharpness Should I Choose?
My advice is to choose a razor with higher sharpness, such as sharpness 3 or 4, for sensitive skin and coarse, dense hair growth.
The sharper the blade, the easier the hairs are cut, and the less frequently you need to go over your skin. Keep in mind, though, that with higher sharpness, the risk of nicks also increases.
So, practicing with a lower sharpness first isn’t such a bad idea.
For softer hair or non-sensitive skin, you can choose a razor blade with lower sharpness.
These blades are still very sharp, so your hairs will be neatly cut, but they are a bit more forgiving to use. By “more forgiving,” I mean: because they are less sharp, the chance of nicks is smaller.
However, you still need to be cautious.
Is It Dangerous to Shave with a Single-Blade Razor?
This brings me to a frequently asked question about shaving with a single-blade razor:
Is it dangerous? The answer is no, it’s not dangerous. As long as you use common sense, of course.
Think of it like using a sharp kitchen knife to chop vegetables. It’s safe, but you have to know what you’re doing.

Tips for Shaving with a Single-Blade Razor
Here are some tips for shaving with a single-blade razor:
- It’s important to know that you don’t need to apply pressure to the razor. Instead, let the razor “work for you.” Hold the razor loosely and let it glide over your skin on its own. The more pressure you apply to the razor, the greater the chance of nicks.
- Shave at a 30-degree angle. This will allow the razor blade to meet your skin properly and cut the hairs neatly.
- Replace the razor blade after 8-10 shaves. When the blade no longer glides smoothly over your skin, you’ll know it’s time to change it.
- Store your used razor blades and recycle them once you’ve used up the entire (refill) package.

To shave or not to shave is a choice, shaving irritation now thankfully also!
YIONN has developed the perfect product for every step of your shaving routine!
You’re fed up. Those annoying red bumps, ingrown hairs, and itching after shaving your bikini line, underarms, and legs. It leaves you feeling frustrated and anything but confident.
No woman should ever feel that way, and neither should you!
First, let me reassure you: there’s nothing wrong with your skin. Your skin is simply doing what it’s designed to do, reacting to the stress of shaving, which leads to unwanted side effects like itching and red bumps.
That’s not the result we women want, so we need to give our skin and nature a little extra help. And that’s exactly what YIONN products are designed to do!

I often used such things but with me it never helped while others were always satisfied with it and I had exactly the same with this product, but had ordered it anyway and it took a little longer with me but it definitely helped!

Get rid of your shaving irritation within 3 weeks: or your money back

From registered nurse to hair removal expert:
I am Wendy, the founder of YIONN.
I know better than anyone what it is like to go through life with shaving discomfort.
After desperately trying every possible way and remedy for red razor bumps and ingrown hairs, I was fed up.
I decided to find a solution to my shaving irritations that worked and it did!
I developed Raka, a caring lotion based on rose water, camphor and willow bark, which, by applying thinly to the problem area, easily and quickly calms the skin after hair removal, prevents red bumps and allows the hairs to grow out – instead of in – again.
And with that, I could finally say goodbye to my insecurities and discomforts.
Hallelujah.
When it later turned out that Raka was not only for me, but also for many other women, I started making several other products around it that can make hair removal a pleasant experience again.
And because I’m so convinced it works and I don’t want to keep your money in the rare case you’re not satisfied with it I came up with the unique YIONN within 30 days money-back guarantee (a guarantee you never normally get on hygiene products).
