What Are Glycolic Acid And Kojic Acid?

Before we try to get into glycolic acid vs kojic acid, let's understand what they do for us:

1. Glycolic Acid

Sugarcane is the source of the alpha-hydroxy acid (AHA) glycolic acid. Known for its small molecular size, it penetrates deeply into the skin, making it one of the most effective exfoliating acids.

Key Benefits Of Glycolic Acid:

• Exfoliation: Glycolic acid dissolves the bonds between dead skin cells, promoting their removal and revealing fresher, smoother skin underneath.
• Improved Texture: Frequent use can make skin feel and look softer by reducing wrinkles, fine lines, and rough spots.
• Boosts Collagen Production: Glycolic acid stimulates collagen synthesis, which helps improve skin elasticity and firmness.
• Reduces Hyperpigmentation: By promoting cell turnover, it can help fade dark spots, acne scars, and uneven skin tone.
• Prevents Acne: Its exfoliating properties help unclog pores, reducing the occurrence of blackheads and breakouts.

How To Use Glycolic Acid:

• Glycolic acid is found in various skincare products, including cleansers, toners, serums, and chemical peels.
• For beginners, it’s best to start with a lower concentration (around 5-10%) to minimise the risk of irritation.
   

2. Kojic Acid

A naturally occurring substance, kojic acid, is produced by fungi or the fermentation of specific foods, such as rice and soy. It is primarily known for its skin-lightening properties. Unlike glycolic acid, kojic acid doesn’t exfoliate but works to reduce pigmentation by inhibiting melanin production.

Key Benefits Of Kojic Acid:

• Brightens Skin: Kojic acid is highly effective at reducing dark spots, sun damage, and melasma, resulting in brighter skin and complexion.
• Treats Hyperpigmentation: It works well to cure uneven skin tone because it specifically targets the enzyme tyrosinase, which is important for the synthesis of melanin.
• Antioxidant Properties: Kojic acid provides mild antioxidant benefits, helping protect the skin from environmental damage.
• Anti-Inflammatory: It can help soothe inflamed skin and reduce redness associated with acne or irritation.
• Compatible With Sensitive Skin: Despite its potency, kojic acid is generally kinder than many other active ingredients, which makes it appropriate for people with sensitive skin.

How To Use Kojic Acid:

• Kojic acid is frequently present in soaps, creams, and serums.
• Consistent use is key to seeing results, but it’s essential to follow product instructions to avoid overuse, which could lead to irritation.
• As with glycolic acid, using sunscreen is crucial when incorporating kojic acid into your routine.

Is Kojic Acid Or Glycolic Acid Better?

Both kojic acid and glycolic acid are effective but work differently, so the "better" choice depends on your skin's concern as well as skin type. Kojic acid is a natural compound derived from fungi and is excellent for reducing pigmentation and dark spots by inhibiting melanin production. It’s gentle and specifically targets uneven skin tone.

Glycolic acid, on the other hand, is an alpha-hydroxy acid (AHA) that exfoliates the top layer of skin, helping with dullness, fine lines, and clogged pores. It also brightens skin indirectly by promoting cell turnover.

If you want to target hyperpigmentation, kojic acid is better. If you need overall exfoliation and brightness, glycolic acid may work better. For some, combining both under proper guidance gives the best results. So, what floats your boat, make it a part of your skincare routine.

Which Acid Is Best For Brightening Skin?

For skin brightening, glycolic acid and vitamin C are highly effective. Glycolic acid exfoliates the skin, removing dead cells and revealing a fresh, glowing layer beneath. Vitamin C is an antioxidant that reduces dullness and evens out skin tone. Kojic acid is also excellent for brightening, especially for reducing dark spots and pigmentation. However, it is usually milder than glycolic acid.

Ultimately, the best acid depends on your skin type. Glycolic acid suits normal to oily skin but can be irritating for sensitive skin. Kojic acid is gentler, making it ideal for people with sensitive or pigmentation-prone skin. If used together, they can deliver complementary benefits but should be introduced gradually to avoid irritation.

What Is More Powerful Than Kojic Acid?

Tranexamic acid and azelaic acid are the skincare acids that have more potency than kojic acid for treating hyperpigmentation. Tranexamic acid is a synthetic compound that reduces dark spots and redness by interfering with the melanin pathways, making it effective for melasma.

Azelaic acid, derived from grains like barley, is another potent option. It lightens pigmentation and helps with acne and rosacea due to its anti-inflammatory and antibacterial properties.

Another strong ingredient is hydroquinone, which works quickly on severe pigmentation but may cause irritation with long-term use. Kojic acid is gentler, so it's better for sensitive skin or mild cases.

Expert’s Advice

Glycolic acid and kojic acid have distinct functions but can work well together. Glycolic acid, a type of exfoliating AHA, is perfect for refining skin texture, clearing clogged pores, and boosting overall brightness. It's ideal for individuals with dull, uneven skin or initial signs of ageing. 

Kojic acid, sourced from fungi, serves as a mild yet potent solution for diminishing dark spots and hyperpigmentation by blocking melanin synthesis. If you aim to illuminate skin or address pigmentation, kojic acid is a good option. Choose glycolic acid to achieve smoother, radiant skin with reduced fine lines

The Final Say

Deciding between glycolic acid and kojic acid depends on your particular skin issues and concerns. If you want to exfoliate, enhance texture, and increase collagen, glycolic acid is the ideal choice. Conversely, if your main goals are to lighten, diminish dark spots, and address hyperpigmentation, kojic acid is the superior option. 

FAQs

1. How do you use kojic acid and glycolic acid together?

Use glycolic acid first to exfoliate and prepare your skin, allowing better absorption of kojic acid. Apply glycolic acid 2-3 times a week at night, followed by kojic acid. Avoid using them on the same day if your skin is sensitive, and always follow with sunscreen during the day to prevent irritation.

2. Between Glycolic acid vs Kojic acid, which is better for tan removal?

Glycolic acid works better for tan removal as it exfoliates dead skin cells, revealing fresh, brighter skin. Kojic acid is gentler and better for targeting specific pigmentation or dark spots. For faster results, glycolic acid is more effective, but kojic acid is safer for sensitive skin.

3. Is glycolic acid better for anti-ageing than kojic acid?

Yes, glycolic acid is better for anti-ageing. It stimulates collagen production, reduces fine lines, and improves skin texture. Kojic acid, while excellent for pigmentation, doesn't address signs of ageing directly. For anti-ageing and brightening, glycolic acid is more effective, though kojic acid can complement it by reducing age spots.

4. How long does it take to see results with glycolic acid and kojic acid?

With glycolic acid, you may see brighter skin and smoother texture within a week, while collagen-related benefits take a few weeks. Kojic acid takes 4-8 weeks to show a significant reduction in pigmentation. Consistency, proper use, and skin type influence the speed of results for both acids.
