Let’s find out. 

In this blog, learn about the benefits & uses of kojic acid and alpha arbutin, what they do, and which is better of the two for you. Read on. 

What is kojic acid?  

Kojic acid is a naturally occurring compound produced from various types of fungi, fermented rice, soy sauce, and sake production. Kojic acid penetrates the skin and inhibits the tyrosinase enzyme production, which plays a key role in melanin production. By regulating and slowing melanin synthesis, it effectively reduces the appearance of dark patches, discoloration, spots, tanning, and uneven skin tone and prevents them from reappearing. 

What are the benefits of kojic acid for the skin?

1. Brightens Skin

Kojic acid is known to lighten skin by reducing dark spots, hyperpigmentation, and post-inflammatory marks. It also helps reduce blemishes caused by sun damage, acne, or melasma. 

 2. Reduces Tan: 

It also fades sun-induced tanning over time, leaving your skin even-toned.  

Use of kojic acid: The best way!

  • Kojic acid is typically used in lower concentrations of 1%–2%.
  • It is best to use a kojic acid serum for more effective results. Additionally, you can also use creams, soaps, and face washes infused with kojic acid.   
  • If using a serum, dispense a few drops of kojic acid serum on your skin and pat it in. 
  • If using a cream, apply it directly on the affected areas, and follow up with a moisturizer. 
  • Always follow up with sunscreen during the day, as kojic acid can make the skin more sensitive to UV rays.  

Are there any side effects of using kojic acid?

  • Avoid using concentrated kojic acid on your skin daily if you have hypersensitive or reactive skin.  
  • It can make your skin more sensitive to sun damage. Therefore, always follow up with sunscreen during the day. 
  • It can also dry or irritate your skin if you have allergies or sensitivity. Always perform a patch test before incorporating kojic acid into your routine.  

What is alpha arbutin?  

Alpha arbutin is a plant-derived compound extracted from bearberry, cranberry, or mulberry leaves. Like kojic acid, it is a tyrosinase inhibitor that fades sun tan and brightens the skin. It gradually releases hydroquinone which makes it gentle on the skin and less likely to irritate or cause any sensitivity.  

What does alpha arbutin do to the skin? Uses of alpha arbutin!

1. Lighten and brighten the skin

Alpha arbutin helps fade dark spots, acne scars, blemishes, and melasma without irritating.  

2. Evens skin tone: 

Consistent use of alpha arbutin reduces dark spots on your skin and promotes a uniform complexion and skin tone.  

3. Safe and gentle

Unlike kojic acid which can irritate your skin, alpha arbutin is gentle and safe to be used on all skin types.  

How to use alpha arbutin?

  • It is best to use alpha-arbutin in a lower concentration of 2% or less in serums and creams. You can try the 2% Alpha Arbutin & Hyaluronic Acid Face Serum
  • You can use it daily in the form of serums or face wash twice. 
  • Follow up with a nourishing moisturizer and a sunscreen to protect your skin from further pigmentation.
