Is your skin parched, dry, and in serious need of a moisture hit?
Or maybe you require something more fortifying to prop up your skin’s protective barrier.
Or could it be your skin’s feeling a little blah and needs a pick-me-up?
Whatever your concern, we have you covered.
In the form of wonderful allantoin.
An ingredient that often flies under the radar.
So we’ve made it our mission to give this skin-loving ingredient the spotlight it deserves.
What the Heck is Allantoin Anyway?
Allantoin is also known as 5-ureidohydantoin or glyoxyldiureide.
The active moisturising ingredient found in the root of comfrey In its organic form, it is found in several other plants, such as sugar beet, comfrey, chamomile, tobacco seed, and wheat sprouts.
Traditionally the comfrey leaves were used to help heal minor skin injuries and swelling.
Today this versatile ingredient is used to treat wounds, eczema, burns, psoriasis, acne inflammation, and other skin eruptions.
Phew. And if that wasn’t enough, allantoin also works as an antioxidant, encouraging new cells, and shedding dead skin cells, helping to give skin that youthful glow. (Thornfeldt, 2005).
Allantoin in Skincare
Allantoin is non-allergenic, non-toxic, odourless, and completely safe for use.
Its primary role is to speed up your skin’s natural healing process.
Because of its wonderful properties, the FDA has even gone as far as to approve it to prevent and protect chafed, chapped and cracked skin.
It’s also a natural humectant, helping to increase the water content in your skin.
10 Skin Healing Benefits
Allantoin is clever in interacting with the skin’s keratin to thin out an abnormally thick epidermis (outer layer of skin).
This is great because we want this layer to be constantly shedding and producing more cells, which is how you get a faster transit time of the epidermal skin cells, keeping skin healthy and plump.
As we age, the transit time of the cells from the base layer of the epidermis to the top layer takes longer, causing the skin to become dull and dry.
Allantoin helps cell proliferation, replenishing depleted, dry skin with its natural exfoliating action.
Allantoin also helps synthesise collagen – a fibrous protein found in the dermis (lower layer of skin) that keeps skin elastic and supplies, decreasing with age and leading to sagging skin – allantoin boosts this.
It helps to hydrate the skin by exfoliating and removing dead skin cells that prevent natural humectants from binding and retaining water in the skin’s tissues.
Allantoin used in cosmetics is a by-product of Diazolidinyl Urea’s production, which is also considered a hydrating ingredient. At more significant percentages, it is thought that allantoin may also have the same keratolytic effects as urea.
It is well-known for stimulating rapid cell regeneration stimulating healthy tissue growth.
Research has found isd it is incredibly healing for wounds and can clear away dead skin cells, making healthy new tissue.
Did you know? One of the reasons that maggots have such a beneficial effect on the healing of infected wounds is that they excrete allantoin.
Allantoin is an emollient that keeps skin moisturised, helping to counteract dryness and roughness.
Various research has demonstrated that allantoin, in combination with onion extract, successfully treats scars; one study found that it also helps protect against UV-induced cell damage.
A large number of proteins and lipids are naturally found in the outer layer of skin, referred to as keratinisation; if this gets out of balance, more keratin than usual is produced, and the structure of the barrier function is changed, skin becomes rough and scaly and inflamed.
As discussed in the exfoliation section – allantoin, by its very nature, is keratolytic, gently softening the keratin and keeping the skin smooth.
It is considered an excellent anti-irritant and calming agent, soothing inflamed skin and encouraging sensitive skin to become more resilient.
More than a match for very dry or irritated skin, Miracle Cleanse and Nectar Treatment Balm harness the benefits of this wonderful herb in the form of comfrey, helping to bring comfort and relief to troubled skin.
#9 Hair Saviour
No article would be complete without mentioning its iattractiveful benefits to the hair and scalp; Its anti-irritant properties help reduce redness and leave the scalp feeling soothed.
#10 Heals seborrheic dermatitis
Allantoin has active keratolytic properties, which means it is the ideal ingredient for combatting seborrheic dermatitis, breaking down large particles in dead skin cells. It also helps improve the softness and elasticity of hair whilst enhancing shine.
Wow, after reading this, we think you’d agree; it’s a beautifying ingredient we need to introduce into our skincare routine—all hail allantoin.
To Conclude. The naked truth
When I first journeyed into the world of formulation, I was fortunate enough to work with a well-known herbalist from Switzerland who introduced me to allantoin’s wonderful properties as a skincare ingredient and its ability to regenerate the skin at a cellular level.
Even at low concentrations of up to 0.5%, it can be very effective; one study found that the inclusion of just 0.2% demonstrated significant improvement in over 90% of women with redness and cracking symptoms.
But wait! There is more. Allantoin is thought to be amphoteric, which also reacts as an acid and a base.
Essentially, this means that when used in combination with various other chemical substances, it neutralises them, which is thought to avoid the potential irritation caused by other ingredients, thus making it an excellent inclusion for use in products for sensitive skincare.
One final note, as one of my readers kindly pointed out; most of the allantoin used in cosmetics is largely lab-synthesised now, that is, of course, unless you are lucky enough to work with a traditional herbalist, as I have had the good fortune to do, here at NC we use this nature-identical form.
