This lovely, simple, and affordable product has become something I don't want to be without. I am 47, with very sensitive and reactive dry skin. This cream doesn't feel particularly moisturizing and leaves something of a 'dry' finish on the skin after application, but it's had SUCH a positive impact on my face.

Buy Allantoin For Skin Care

Allantoin is a natural product of nitrogen metabolism in several plants and most mammals. It has been used in numerous cosmetics products for a significant period of time and is proven safe for various human applications. Its greatest benefits are promotion of wound healing, including reduced scar formation after various procedures (ranging from surgical scars to tattoo removal). To this purpose, allantoin can be used preventively as well as on already formed scars. Furthermore, it is an effective antimicrobial substance, used in alcohol-free hand sanitizers. Allantoin-containing solutions have been used in treating various infections, primarily onychomycosis (nail fungus) and trichomoniasis. Its anti-inflammatory properties made it useful in dermatitis treatment. Generally, allantoin is combined with extracts of onion or other plants, but its effectiveness was also demonstrated while applying without supplements.

Key benefits of Allantoin in skin care:

  • Anti-inflammatory [2] [13]
  • Wound healing support [2] [4]
  • Anti-bacterial [9] [10] [11]
  • sun damage repair [2] [13]
  • Scar care [6] [7] [8]

About Allantoin in DIY Skin Care

Allantoin is the final product of nitrogen metabolism in most mammals, except primates. It is also naturally found in plants, such as sugar beets or wheat sprouts [1]. Historically, allantoin has been extracted from the comfrey plant root and leaves, but due to wide use in pharmaceutical or cosmetics products it is now manufactured by chemical synthesis [2]. This agent is used in over 1300 cosmetic preparations, where it is added to final concentrations in the range  of 0.0001 to 2.0 % [3]. During its 70-year history of use in cosmetics, allantoin has been incorporated in a wide range of clinical skin care products, used to treat wounds, ulcers, burns, dermatitis, psoriasis, impetigo, and acne [2]–[5]. It is described as antiphlogistic (reduces inflammation), antioxidant (reduces damage caused by free radicals, implicated in ageing and cancer) and keratolytic (potent against undesired formations of keratin, such as warts). It even induces cell proliferation, thus promoting tissue repair and even peripheral nerve regeneration [1], [2].

The primary area of allantoin use in skin care is wound treatment. Interestingly, the details of the mechanism by which it acts (including regulation of inflammatory reactions) have become known only recently [4]. In spite of that, pharmacological preparations containing allantoin were proven to be effective much earlier. For example, a study from 1994 found that treating thoracic surgery scars with allantoin-containing mixture improved their appearance and reduced width. Scar development was judged as good or very good in more than 90 % of patients receiving this treatment [6]. The same mixture can also be used for scar prevention. Such early application can provide even better results, among them decrease in painfulness, improved color and almost double reduction in size [7]. Finally, it was found that incidence of scars after tattoo removal by laser was much lower in a group that received allantoin-based treatment, compared to a control group [8]. These research report no adverse side effects, and safety of allantoin has been extensively confirmed [3].

Allantoin also has a marked antimicrobial effect. In a solution with benzalkonium chloride and surfactants, allantoin has been proved effective for treating onychomycosis (fungal infection of toe nail), with 90% of the patients indicating excellent or good improvement of the nail condition [9]. A similar formulation can be used to produce a hand sanitizer capable of outperforming alcohol-containing rivals – this product has also been used in practice, successfully combating infection spread among children in elementary school [10], [11]. Due to this antimicrobial effect, allantoin has also been investigated in experimental treatment of Trichomonas vaginalis infection (trichomoniasis), where it reduced the incidence of reported infection symptoms [2], [12].

In therapeutic applications, allantoin is often combined with other plant extracts. In research on wound healing it is typically used with onion (Allium cepa) extract [6]–[8]. Together with Vitis vinifera extract, glycyrrhenetic acid, and telmesteine, allantoin is found in Atopiclair (Zarzenda), a non-steroidal anti-inflammatory agent for treatment of allergic diseases of the skin, such as atopic dermatitis [13]. On the other hand, application of allantoin without any other active ingredients also actively helps in the wound healing process [4].

  • Allantoin is compatible with most ingredients used in personal care formulations.
  • Water solubility at monograph-approved levels is an issue.
  • Suspending the material in a thick base is the best way to resolve this issue.
  • When conducting stability testing, care must be taken to look for Allantoin recrystallization.
  • To incorporate 0.5% Allantoin, or more, into an emulsion product, the emulsion is made and Allantoin is added during the cooling process below 50 °C.
  • Good agitation is required to thoroughly disperse the Allantoin to achieve a suitable suspension.
  • Addition of Allantoin at 0.5% or more or at temperatures above 50 °C in aqueous systems can cause solubilization and recrystallization upon cooling into larger particles which are perceptible during product use.
  • Soluble in the aqueous phase
  • Insoluble in commonly used oils
  • Add to water and dissolve at 50°C
  • Alternatively add at 25°C under stirring
  • A pH between 4 and 8 is recommended
