“AHA” in Kuramoto no Shizuku refers to?

AHA for preventing dark spots

One of the various ingredients included in “Kuramoto no Shizuku” is “AHA (fruit acid).” You might occasionally come across this ingredient when looking at skincare products like facial cleansers and makeup removers. But do you know what it is? In fact, AHA is one of the important elements that leads to beautiful skin. In this article, we will introduce you to AHA in detail.

AHA for Achieving Beautiful Skin

AHA stands for “alpha hydroxy acid,” a naturally derived ingredient found in fruits like apples and citrus fruits. It is also known as “fruit acid.” AHA is characterized by its mildness and works by gently removing old, dead skin cells through its acidic properties, making it an excellent match for the delicate skin of Japanese people. It is commonly used in skincare products, including facial soaps, creams, and lotions, and is widely utilized in various skincare routines.

The Effects of AHA

The most anticipated effect of AHA is its “peeling action”! Peeling, as the name suggests, refers to the removal of old, dead skin cells from the surface of the skin, revealing a more translucent and radiant complexion. As we age, the skin’s turnover cycle lengthens, making it harder for old skin cells to shed, which can lead to dullness or even acne. AHA helps to promote skin cell renewal, supporting a more regular skin turnover cycle.

In addition, AHA is known to stimulate collagen production. Collagen fibers can become damaged due to aging or sun exposure, leading to sagging skin. By using skincare products that contain AHA, the fruit acid can stimulate the collagen fibers deep within the skin, promoting collagen production. With continued use, AHA-infused skincare can help replenish the lost collagen, restoring plump and elastic skin.

Differences in AHA Ingredients

AHA contains several types of ingredients, such as malic acid and citric acid. This time, we will introduce three types of AHA included in the “Kuramoto no Shizuku” series.

1. Citric acid

[Effect] Skin Revitalization, Antioxidant Action
This is a type of AHA found in citrus fruits. It has very mild effects, including exfoliation and acne prevention. It is also expected to have an astringent effect, tightening the skin and promoting a firmer complexion.

2. Malic acid

[Effect] Softening of Dead Skin Cells
This ingredient, derived from green apples, is expected to soften dead skin cells. It is commonly used in peeling products and is known for its mild action, making it less irritating to the skin.

3. Glycolic acid

[Effect] Dissolving Old Skin Cells
Glycolic acid, a type of AHA found in sugarcane and grapes, works by weakening the bonds between corneocytes, making it easier to remove excess dead skin cells. Due to its small molecular size, it penetrates the skin deeply, offering a strong peeling effect. It is often used in medical-grade peeling treatments.

The Difference Between AHA and BHA

AHA is often compared to another similar ingredient, BHA. BHA stands for “beta hydroxy acid,” commonly known as “salicylic acid.” In fact, this ingredient is also included in “Kuramoto no Shizuku” and plays a role in improving the skin.

BHA has a higher exfoliating effect compared to AHA and is lipid-soluble, meaning it can dissolve and remove excess oil that clogs pores. While it tends to be slightly more irritating than AHA, it is particularly effective for promoting skin turnover and improving pore congestion.

4. Salicylic Acid

[Effect] Dissolving Excess Oil in Pores, Removing Old Skin Cells
Salicylic acid is recommended for persistent acne and oily skin. If you have oily skin and find that water-soluble ingredients are less effective, salicylic acid, being lipid-soluble, may be a better fit for your skin. It penetrates oily skin effectively, helps clear clogged pores, and is effective for acne care. Additionally, salicylic acid has antimicrobial and preservative properties, which can help prevent the growth of acne-causing bacteria, making it a good choice for those looking to manage acne-prone skin.

Important points to note when using AHA and BHA

While AHA and BHA ingredients offer significant exfoliating benefits, they can sometimes cause skin irritation when used in skincare products. If you experience any signs of irritation, such as redness or a burning sensation, discontinue use immediately.

When you first start using these products, you may notice temporary dryness or a decrease in the skin’s barrier function due to the removal of dead skin cells, which can lead to increased water loss from the skin. This is a normal response and should improve as your skin adjusts.

Additionally, after exfoliation, your skin becomes more sensitive and more prone to UV damage. To protect your skin, ensure you apply sunscreen and take other sun protection measures.
