Lactobionic Acid
Product Introduction
Lactobionic Acid is a polyhydroxy acid (PHA) that belongs to the same family as other well-known skincare acids like alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs). It is derived from lactose, a milk sugar, and is known for its excellent moisturizing properties and gentle exfoliation. Lactobionic acid has a larger molecular size compared to other acids, which makes it suitable for sensitive and dry skin types.
Lactobionic Acid is a carboxylic acid that contains a lactone ring. It is a polyhydroxy acid that has six hydroxyl groups attached to the molecule. These hydroxyl groups make lactobionic acid an excellent humectant, as they attract and bind moisture to the skin. Lactobionic acid is a gentle acid that does not irritate the skin, making it ideal for sensitive skin types.
In addition to its humectant properties, lactobionic acid also has antioxidant properties. It helps to protect the skin from free radical damage, which can lead to premature aging and other skin concerns. Lactobionic acid has been shown to improve skin texture and tone, reduce the appearance of fine lines and wrinkles, and even out skin discoloration. It is a versatile ingredient that can be used in a variety of skincare products, including cleansers, toners, serums, and moisturizers.

Lactobionic Acid has many benefits for hair health as well. It can help to strengthen the hair shaft, reducing breakage and split ends. Lactobionic Acid also helps to nourish the hair, providing it with essential nutrients and hydration. This can result in shinier, healthier-looking hair.
In addition to its strengthening and nourishing properties, lactobionic Acid has been found to have antioxidant effects on the hair. This means that it can help to protect the hair from damage caused by free radicals, which can lead to premature aging and hair loss.
Furthermore, Lactobionic Acid has been shown to have a soothing effect on the scalp, making it a great ingredient for those with sensitive or irritated scalps. It can help to reduce inflammation and redness, while also promoting a healthy scalp environment for optimal hair growth.

Lactobionic Acid vs Hyaluronic Acid
Lactobionic Acid and hyaluronic acid serve different purposes in skincare. Lactobionic Acid provides gentle exfoliation and antioxidant benefits while offering moisturizing properties.
Hyaluronic Acid, on the other hand, is a humectant that attracts and retains moisture, providing intense hydration to the skin. Both acids can be beneficial and can complement each other in a skincare routine.
Lactobionic Acid vs Gluconolactone
Gluconolactone is another polyhydroxy acid (PHA) similar to lactobionic acid. Both acids offer gentle exfoliation and moisturizing properties, making them suitable for sensitive skin. However, lactobionic acid has a larger molecular size, which contributes to enhanced moisture retention.
Gluconolactone may be better suited for individuals with oily or acne-prone skin, while lactobionic acid is an excellent choice for dry or sensitive skin types.

Applications
● Antioxidant
● Humectant
● Exfoliates
● Anti-inflammatory
Advantages
● Suitable for sensitive and dry skin types
● Lactobionic Acid has a larger molecular size which contributes to enhanced moisture retention.
