One of the lesser-known ingredients similar to Cica and madecassoside, allantoin is a powerhouse ingredient known for its skin-soothing and calming effects. This ingredient recently gained popularity in South Korea as the demand for more sensitive skin-friendly products grew. Luckily, Allantoin is an ingredient that works well for all skin types, including sensitive skin.

If you haven’t heard, or you’re curious to know more about allantoin, read on further! Below, we’ll discuss all its functions, uses, and benefits for the skin.

What is Allantoin?

Although allantoin has been existing for decades, it is a vastly popular ingredient found in K-Beauty products, commonly in skincare. It is also known as aluminum dihydroxy allantoinat, a chemical compound that can be found in both the human body and several plants such as comfrey, sugar beet, tobacco seeds, chamomile, and wheat sprouts. It is non-toxic and is commonly used as an ingredient that is used for its healing properties, outside of cosmetic applications.

The most common source of allantoin comes from comfrey, which has been used to treat skin issues such as rashes, wounds, swelling, and even minor injuries. It is also the same source used for most cosmetic products. It undergoes lab processing so, the toxins can be removed and can safely be used in products. There are also lab-made allantoin variants that are equally effective as those derived from plant-based ones.

The Benefits of Allantoin for Skin

allantoin is best known as an all-rounder skincare ingredient because of its many benefits for the skin.

Soothing and Anti-Inflammatory

It is best known for its soothing and calming effects on the skin. For inflamed and irritated skin, your skin can find relief with this ingredient included in the products you use.

Moisturizing and Smoothening

Allantoin also doubles as an emollient that moisturizes the skin. As it provides moisture, it keeps the skin smooth and soft.


Allantoin is also an effective treatment for wounds, dermatitis, acne, burns, rashes, and irritations.


This ingredient is a keratolytic too, which helps get rid of dead skin cells on the skin. Ideal for those with dull skin, it works from within the skin to the top layer of the skin to reveal a renewed, brighter skin.


Allantoin provides hydration and prevents moisture loss by retaining water in the skin cells. In doing so, it keeps the skin plump and firm.

Rejuvenating and Anti-Ageing

In connection with the previous benefit, allantoin also promotes cell regeneration. It also helps in collagen synthesis. Collagen is known to hold the cells together beneath the skin.

Skin Protecting

This ingredient also has antioxidant properties that help protect against free radicals and UV pollutants.

Allantoin in Skincare

When Allantoin is good to use, it comes in powder form, which can then be mixed into different products. Allantoin can be found in several cosmetic products such as anti-acne creams, creams, toners, sun care, lip products, moisturizers, masks, and exfoliators. It is also a good thing to note that this hardworking ingredient is very gentle on the skin as well. Allantoin is a great choice for all skin types, especially those with sensitive skin and skin conditions.

Even if nearly everyone can use it, be sure to swatch or test it on your skin to see if it is compatible with it. If you experience any adverse reactions, discontinue use. Some side effects of allantoin include itchiness, irritation, stinging, and burning. Introduce this ingredient slowly into the skin and gradually incorporate it into your daily routine once your skin gets used to it.

The best way to use Allantoin in skincare is to follow how it should be used as instructed per product. It is safe to use daily, day and night.

Can You Combine Allantoin With Other Ingredients?

Allantoin works best when combined with most ingredients, silicone gels or moisturizers, and other emollients. Even if Allantoin has its own exfoliating properties (which is very mild and gentle), it can safely be used with actives such as AHAs, BHAs, Lactic Acids, Salycylic Acids, Glycolic Acids, Retinol, and Mandelic Acids. Since Allantoin focuses more on calming and soothing, there would be no trouble layering products with allantoin with other active ingredients.
