Alpha arbutin VS Beta arbutin? Which Is Better?

In the world of whitening ingredients, arbutin is favored for its significant whitening and antioxidant benefits. Alpha and beta arbutin are like twins, often confusing beginners and natural ingredient buyers alike. Today, let’s talk about the difference between this “twins”, and how to choose for buyers.

What are alpha and beta arbutin?

Arbutin is a naturally occurring plant glycoside compound, which is mainly extracted from plants such as bearberry fruit and pear leaves. It is a natural whitening ingredient which can reduce the production of melanin by inhibiting the activity of tyrosinase, so as to achieve whitening effect. According to their chemical structure, arbutin is divided into two main types: alpha arbutin and beta arbutin. In simple terms, they are like two different “variants” of the same ingredient. The benefits of arbutin for skin include:

Whitening spot

Beta arbutin and alpha-arbutin are two different types of melanin inhibitors.The ingredient is safe for all skin types and is commonly found in cosmetics and skin care products.  The central role of α-arbutin and β-arbutin is to inhibit tyrosinase activity, thereby reducing melanin production. They can effectively reduce pigmentation problems such as spots, freckles, sun spots, and make the skin more uniform and bright. In addition to skin whitening, Alpha Arbutin is an excellent choice to prevent liver spots and other blemishes. This is because it doesn’t produce toxic side effects for melanocytes, and is a safer option than Beta Arbutin powder.

Antioxidant protection

Arbutin has antioxidant properties, which can neutralize free radicals and reduce skin damage caused by oxidative stress. Long-term use of skin care products containing arbutin can help delay skin aging and keep skin young.

Anti-inflammatory relief

Arbutin also has an anti-inflammatory effect, which can relieve skin inflammation and redness, especially suitable for sensitive skin or post-sun repair, making it a very effective supplement for all skin types.

Moisturizing

Arbutin helps skin lock in moisture and enhances the skin’s ability to retain moisture, leaving skin softer and smoother.

High security

Compared with some strong whitening ingredients (such as hydroquinone), arbutin is more mild, less likely to cause skin irritation, and suitable for long-term use.

Difference between alpha arbutin and beta arbutin

Although α-arbutin and β-arbutin have similar mechanisms of action, there are some differences in effectiveness, stability and cost.

Stability

In the world of skincare, stability is like an athlete’s endurance. Alpha arbutin is very good in this regard, it does not break down at high temperatures of 100 ° C and is stable in the pH range of 5.2 to 8.0. But beta arbutin is not so “strong”, when the temperature exceeds 60 ° C, it will start to break down. If your product needs to be treated at high temperatures or if the pH of the formula fluctuates, alpha-arbutin is a more reliable choice.

Security

Safety is a key consideration for whitening ingredients. Although natural, beta arbutin may cause damage to skin cells if used in excessive amounts. Even at higher concentrations, α-arbutin did not have a negative effect on cell growth. So, if you’re more concerned about ingredient safety, alpha arbutin is a milder option.

Price

Beta arbutin is relatively common in the market, and the price is relatively cost-effective. Due to the difficulty of synthesis, the price of alpha arbutin is usually 3 times that of beta arbutin.

If the whitening effect is compared to a running race, alpha arbutin is undoubtedly the faster runner. Studies have shown that α-arbutin inhibits tyrosinase (a key enzyme in melanin production) 10 times more strongly than β-arbutin. In other words, alpha arbutin only needs to use a smaller amount to achieve the same whitening effect as beta arbutin. If you want to see whitening results quickly, alpha arbutin may be a better choice.

Properties α arbutin  β arbutin
Whitening effect Stronger, longer lasting Weaker, but cost-effective
Stability More stable, not easy to decompose Poor stability, easily affected by light and heat
Cost Higher Lower
Application High-end skin care products, strong whitening products Daily skin care products, affordable whitening products

In short, α-arbutin and β-arbutin are the star ingredients in the field of whitening skin care and are widely welcomed for their effective whitening, antioxidant and anti-inflammatory properties. If you are a natural ingredient buyer, you can choose according to your needs. α-arbutin is better in effect and stability, suitable for high-end skin care products; And β arbutin has become the first choice for daily whitening products with high cost performance. Both have a high safety profile, but attention to concentration, sun protection and skin testing is still needed to ensure optimal results and skin health.
