What is Lactic Acid?
Lactic acid is a naturally occurring alpha hydroxy acid (AHA) derived from milk and fruit sugars. It is one of the gentlest AHAs, making it suitable for sensitive skin while providing effective exfoliation. Lactic acid is a key ingredient in many skincare products, including cleansers, serums, and masks, for its ability to improve skin texture and hydration.
How Lactic Acid Benefits the Skin
Lactic acid promotes skin renewal by gently sloughing off dead skin cells, revealing fresher and more radiant skin underneath. This process not only helps reduce the appearance of fine lines and wrinkles but also improves overall skin tone and texture. Moreover, lactic acid is known for its hydrating properties, making it an excellent choice for dry or dehydrated skin.
Where Can You Find Lactic Acid?
Lactic acid is commonly found in over-the-counter skincare products like facial peels, creams, and lotions. It is often combined with other AHAs or BHAs for enhanced exfoliation and skin renewal. Professional treatments, such as chemical peels, also frequently utilize lactic acid due to its efficacy and gentleness.

It is celebrated for its versatility and can address a wide range of skin concerns, including acne, pigmentation, and aging. Niacinamide is suitable for all skin types and is often included in serums, creams, and toners.
How Niacinamide Benefits the Skin
Niacinamide strengthens the skin barrier, enhances moisture retention, and improves skin elasticity. It is also known for its anti-inflammatory properties, which help reduce redness and irritation, making it an excellent choice for sensitive or acne-prone skin. Additionally, niacinamide can minimize the appearance of enlarged pores and even out skin tone, providing a smoother and more refined complexion.

How Does Lactic Acid Work?
Lactic acid works by breaking down the bonds that hold dead skin cells together on the skin's surface. This gentle exfoliation process allows new, healthy skin cells to emerge, resulting in a brighter and more even complexion. Lactic acid's moisturizing properties are attributed to its ability to increase the skin's natural moisture factor (NMF), which keeps the skin hydrated and plump.
The Exfoliating Power of Lactic Acid
The exfoliating power of lactic acid lies in its ability to remove dead skin cells without causing irritation. This makes it an excellent choice for those with sensitive skin or those new to chemical exfoliation. Regular use of lactic acid can help fade dark spots, improve skin texture, and enhance the efficacy of other skincare products by allowing them to penetrate deeper into the skin.
Hydration and Lactic Acid
Lactic acid is unique among AHAs for its hydrating properties. It acts as a humectant, drawing moisture from the environment into the skin. This makes it particularly beneficial for individuals with dry or dehydrated skin, as it helps maintain optimal hydration levels.
How Does Niacinamide Work?
Niacinamide works by enhancing the skin's natural barrier function, reducing water loss, and improving skin elasticity. It also inhibits the transfer of pigment to skin cells, which helps reduce hyperpigmentation and even out skin tone. Additionally, niacinamide possesses anti-inflammatory properties, making it effective in calming irritated or acne-prone skin.
Niacinamide and Skin Barrier Strengthening
One of the primary benefits of niacinamide is its ability to strengthen the skin barrier. A healthy skin barrier is crucial for preventing moisture loss and protecting the skin from environmental aggressors. By reinforcing the skin barrier, niacinamide helps maintain a smooth, hydrated, and resilient complexion.
Anti-Inflammatory Properties of Niacinamide
Niacinamide's anti-inflammatory properties make it an excellent choice for individuals with sensitive or acne-prone skin. It helps reduce redness, irritation, and the occurrence of breakouts, promoting a calmer and more balanced complexion.
Benefits of Lactic Acid
Lactic acid offers a multitude of benefits for various skin concerns. Its gentle exfoliating action helps remove dead skin cells, revealing a brighter and more radiant complexion. Lactic acid also enhances skin texture and tone, reduces fine lines and wrinkles, and boosts hydration levels.
Exfoliation and Skin Renewal
Lactic acid is renowned for its ability to exfoliate the skin gently yet effectively. By promoting the removal of dead skin cells, lactic acid encourages skin renewal, resulting in a smoother and more even complexion.
Improved Skin Texture and Hydration
Regular use of lactic acid can significantly improve skin texture and hydration. Its humectant properties attract moisture to the skin, keeping it plump and nourished. Lactic acid's exfoliating action also helps fade dark spots and hyperpigmentation, leading to a more uniform skin tone.
Benefits of Niacinamide
Niacinamide is a versatile skincare ingredient that offers numerous benefits for the skin. It strengthens the skin barrier, enhances moisture retention, reduces inflammation, and improves skin elasticity. Niacinamide also helps minimize the appearance of enlarged pores and evens out skin tone.

Reduction of Inflammation and Pore Appearance
Niacinamide's anti-inflammatory properties help reduce redness and irritation, making it an ideal choice for sensitive or acne-prone skin. Additionally, niacinamide can help minimize the appearance of enlarged pores, resulting in a smoother and more refined complexion.
