Starch, particularly in the forms of corn starch, rice starch, or potato starch, has a long history of traditional use in skin care. Historically, starches have been applied to the skin to absorb moisture, soothe irritation, and reduce friction, especially in the management of minor rashes, chafing, and as a mild powder for babies or individuals with sensitive skin. Its use as a natural alternative to talcum powder is well-documented, particularly in the late 19th and early 20th centuries. Traditional remedies also include starch baths for soothing inflamed or itchy skin, such as in cases of chickenpox or eczema, where the starch is thought to provide a protective, calming layer on the skin.

However, scientific evidence supporting starch’s efficacy in general skin care is limited. Most available research focuses on its physical properties—such as its ability to absorb moisture and reduce friction—rather than therapeutic skin benefits. While starch is considered safe for topical use in most individuals and can play a role in preventing irritation and keeping skin dry, there is little high-quality clinical evidence to suggest it actively treats or improves underlying skin conditions beyond symptomatic relief. Thus, starch's use in skin care is primarily justified by traditional practices and anecdotal reports rather than robust scientific validation.
