Guide to Proper Exfoliation - AHA

Just like we can’t live without air, our skin needs to breathe. If piled up dead skin cells clog pores, it causes acne and even makes your skin look dull and dry. This happens more frequently as we age, since the process of skin regeneration slows down and it takes more time for our skin cells to shed and regenerate. Therefore, proper exfoliation of dead skin cells on a regular basis is a must if you want a healthy, glowing skin.  

Let’s look into two different types of exfoliation -  physical and chemical.  

Physical Exfoliation

You might be familiar with physical exfoliation - it’s literally scrubbing your skin with exfoliants such as brush or small grains to remove dead skin cells. You might think it is effective since it’s visually satisfying. However, physical exfoliation can lead to over-exfoliating which results in dry, irritated skin. It can even leave you with invisible micro tears on skin.

This leads us to our next option, which might be a great solution for those with extremely sensitive skin. 

Chemical Exfoliation

Simply put, chemical exfoliation uses acids to gently remove dead skin cells. Some of you might think ‘Wow hold up, ACID? Is it safe to use?’. Well, yes! Since it includes a low proportion of gentle and mild acid, it’s 200% safe.  Plus, unlike physical exfoliation, it doesn’t leave micro tears on skin while improving your skin to be smoother and brighter.  

Among all different kinds of chemical exfoliants out there, AHA might be the most commonly used ingredient that is used for skin care. AHAs, which stands for Alpha-Hydroxy Acids, are groups of water-soluble acids derived from fruits and plants. Their main role is to encourage the exfoliation of dead skin cells and reveal healthy, fresh new skin cells.

In this post, we’ll be covering the most well known and widely used acid in the AHA family - Glycolic and Lactic acid.


First up is glycolic acid. Found in sugar cane, its main role is to break down and eliminate dead skin cells. Because of Glycolic acid’s small molecule size, it can effectively penetrate the skin resulting in faster cell turnoverPlus, it has been shown to be effective at stimulating collagen production for supple skin.

Lactic acid, another AHA found in milk, does a similar job to glycolic acid but is a little bit more gentle and mild. It’s more effective at improving skin texture and tone, which is why Cleopatra used to soak in milk for her complexion.



If you have decided to use chemical exfoliator and don’t know which product to begin with, we highly recommend you to try YES, I AM TONER AHA 5%, especially for those with sensitive skin. We were able to formulate the best combination of Glycolic and Lactic acids with Panthenol, an ingredient that provides moisture and nutrients to the skin.

With YES I AM TONER AHA 5%, you will be able to exfoliate dead skin cells without any skin irritation.

Jumiso Brand History

Jumiso Brand History

JUMISO's pathway to put a SMILE ON you.

Phase 1   JU;MISO

Ju : give + Miso : smile = 'Give you Smile' in Korean

From 2016, we started this journey with a mission to make people smile through our skincare products.
At the early stage, we focused more on the visual aspects of smile.                   
We created our own characters as a medium to deliver stories and messages about our slogan, ‘Make You Smile’.
We believe this gave users a better understanding of our brand and products.


Phase 2   Smile ON 

cONfidence + wONder + bONding

Beyond our slogan ‘Make You Smile’, we wanted to talk more deeply about the fundamental factors that make people smile and eventually bring positive changes to our society.

We started the whole process by asking questions such as
“How can we make people smile with our products?”
“How can we make positive changes to the world by making people smile?”
As an answer to those questions, we came up with our new brand philosophy, ‘Smile ON’.
‘Smile ON’ is not only about making you smile - It also contains three essence values that we pursue through our skincare products.

smile cONfidence 

We believe beautiful, healthy skin is the first step to better self-image.
We hope you to be confident in any circumstances.

smile wONder 

We have developed our skin care products based on years of study and valuable user feedback. Now it’s your turn to experience the wonders of Jumiso.

Beyond confident individuals, our ultimate goal is to make people feel belonged and bonded in a community where each and everyone’s values are appreciated.

It’s about making you cONfident.

It’s about showing you skincare wONders.

It’s about making a bONding community.

Daily vitamin dose for your skin

Daily vitamin dose for your skin

We all know that vitamins are essential to human health, but did you know vitamins can even improve our skin condition as well? Just like we take vitamin supplements every day to get healthier, our skin could also get healthier if we apply them on our skin on a daily basis.

In this post, we will be discussing how vitamins can improve our skin condition when applied to skin. To do so, we should take a look over the most commonly used vitamins for skin care - Vitamin A,B and C. 

Vitamin A
If you’re deeply interested in skincare, you might have heard about ‘retinol’. Retinol is a derivative of Vitamin A and its main role is to promote skin turnover and treating acne. Vitamin A can also be effective at improving uneven skin tone.
Vitamin B
Out of 8 different types of Vitamin B family, B3 - a.k.a niacinamide is the most commonly used for skin care solutions. B3 is effective at providing moisture to skin and reducing inflammation. Vitamin B5 (pantothenic acid) can improve the elasticity and texture of your skin.
Vitamin C
Because of its effectiveness, vitamin C is the key ingredient that are found in many anti-aging skin care products. It is a great antioxidant and promotes the production of collagen (which helps your skin to stay firm). It also helps recovering damage from sun exposure and removing dark spots.

Adding Vitamin to your skin care routine

Vitamin for skin sounds awesome, right? Then how should we add vitamins into our skin care routine? Well, don’t worry about it since we’ve got a whole vitamin package for your skin.
