Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Allantoin is a compound commonly used in skin care products for its moisturizing and skin-soothing properties. Its use in treating or supporting sunburn is primarily based on its ability to promote skin healing and reduce irritation. Scientifically, allantoin has been shown in in vitro and animal studies to support cell proliferation, stimulate tissue regeneration, and accelerate wound healing. It also acts as a skin protectant, helping to alleviate dryness, scaling, and minor irritation—symptoms often associated with mild sunburn.

There are some clinical studies and reviews that support allantoin’s efficacy in improving skin repair and comfort in minor wounds and irritations. However, direct clinical evidence specifically assessing allantoin’s effect on acute sunburn in humans is limited. Most of the available evidence is extrapolated from its general wound-healing and soothing effects. Regulatory agencies in several countries (such as the US FDA) recognize allantoin as a safe and effective skin protectant for minor skin irritations, which includes sunburn to some extent.

In summary, while allantoin is widely used in over-the-counter sunburn products and there is some scientific rationale for its inclusion, the direct clinical evidence for its effectiveness specifically in sunburn is limited, and thus the evidence rating is moderate (2/5).
