Is RMS Beauty Soy free?

An estimated 0.6% of the population suffers from a soy allergy, making cosmetic ingredients a significant concern for many. So, is RMS Beauty soy free? The answer is nuanced, requiring a closer look at specific products despite the brand's general claims of being soy-free.

Quick Summary

RMS Beauty promotes its products as generally soy-free; however, ingredient lists for certain items reveal the presence of soy-derived components, requiring vigilance for sensitive individuals. The brand's transparent labeling helps consumers check specific ingredients, but checking each product is still essential for those with a soy allergy or sensitivity.

Key Points

Initial Claim: RMS Beauty generally promotes itself as a soy-free brand, a key aspect of their clean beauty philosophy.
Ingredient Discrepancy: A closer look at product-specific ingredient lists reveals contradictions, with some items containing soy-derived ingredients like Glycine Soja (Soybean) Oil.
Specific Product Warning: The RMS Supernatural Radiance Serum SPF 30 has been identified as containing soybean oil, despite the brand's overarching soy-free marketing.
Individual Checks Required: Due to this inconsistency, individuals with soy allergies must check the ingredient list of every product, rather than relying on the brand's general claim.
Transparency is Key: While the brand is transparent about listing ingredients, it places the onus on the allergic consumer to scrutinize each label carefully.
Hidden Soy: Be aware that soy can appear under different names like lecithin, so vigilance is required for those with severe allergies.
Safe Vitamin E: The brand does explicitly mention using soy-free Vitamin E, which is a reassuring detail for one specific ingredient.

RMS Beauty's Stated Commitment to Being Soy-Free

RMS Beauty has built its brand on the promise of using raw, food-grade, organic, and clean ingredients. On their website and through various retailers, they explicitly state that their products are soy-free. This commitment is a major selling point for individuals with allergies or sensitivities to soy. The brand emphasizes transparency, proudly disclosing every ingredient used in their cosmetics. In some instances, they clarify that even potentially soy-derived ingredients like Vitamin E are sourced as non-GMO and soy-free. This creates an expectation of complete soy-free assurance across their entire product line.

The Contradiction: A Look at Specific Ingredients

While RMS Beauty's general claim is that its products are soy-free, a detailed examination of specific product ingredient lists reveals an important contradiction. For example, the RMS Supernatural Radiance Serum SPF 30 lists Glycine Soja (Soybean) Oil as an inactive ingredient.

This is a key example of why relying solely on a brand's top-level marketing can be risky for those with severe allergies. The presence of Glycine Soja (Soybean) Oil, which is directly derived from soybeans, clearly conflicts with the 'soy-free' promise. Other products reviewed by third-party ingredient checkers may also include or exclude soy-derivatives based on formulation, which is why cross-referencing is critical.

Why Ingredient Checking is Non-Negotiable for Allergy Sufferers

For those with a soy allergy, the risk of a reaction from cosmetic products is real. As highlighted by dermatologist Kathleen Cook Suozzi, patients with peanut or pollen allergies may also have co-existing soy allergies, making careful product selection vital. Soy can appear in cosmetics in various forms, not just as a primary oil. It can be found in ingredients like lecithin, derived from soybeans, which is used as an emulsifier. While some sources confirm RMS uses lecithin, it may or may not be soy-derived, underscoring the need for further inquiry or caution.

Comparison: Brand Claim vs. Ingredient List Reality


Feature	RMS Beauty's General Claim	Reality for Select Products	Implications for Consumers
Soy-Free Status	Generally promoted as a soy-free brand.	At least one product, Supernatural Radiance Serum SPF 30, contains Glycine Soja (Soybean) Oil.	Those with soy allergies must check every single ingredient list.
Ingredient Transparency	Claims to be transparent and proudly reports every ingredient.	Lists `Glycine Soja (Soybean) Oil` on the label for Supernatural Radiance Serum SPF 30.	Transparency is present, but requires the consumer to actively scrutinize the labels.
Vitamin E Source	Uses a non-GMO, soy-free Vitamin E.	Verified on their own website as being soy-free.	Provides reassurance for this specific ingredient, but other soy derivatives are still possible.

A Broader Look at Soy-Free Alternatives

For those who prefer to avoid RMS Beauty entirely due to this inconsistency or for those seeking broader options, several brands are recognized for their soy-free offerings. This includes brands like ILIA, Kosas, and 100% Pure, among others. However, the same rule applies: always check the most current ingredient list for any product before purchasing, especially if dealing with a severe allergy. Cosmetic formulations can change over time without much notice, making due diligence the best approach for safety.

Final Conclusion

So, is RMS Beauty soy free? The most accurate answer is that while the brand markets itself as soy-free, and many of its products are, not all are. The discovery of Glycine Soja (Soybean) Oil in at least one product, the Supernatural Radiance Serum SPF 30, shows that this is not a universal guarantee across their entire line. Therefore, for individuals with soy allergies, it is essential to look beyond the brand's broad claims and meticulously review the ingredient list for each individual product before use. This practice of careful ingredient scrutiny is the best way to ensure safety and avoid potential allergic reactions. For further information on cosmetic ingredients, consulting resources like INCIDecoder can be helpful.

Note: Formulations can and do change. For the most up-to-date ingredient information, it is best to check the product label on the physical packaging before purchase.

Frequently Asked Questions

No, despite the brand's claims, it is not 100% guaranteed. Ingredient lists for some products, such as the Supernatural Radiance Serum SPF 30, include soy-derived ingredients like Glycine Soja (Soybean) Oil.

For individuals with soy allergies, it is recommended to check the ingredient list for every RMS Beauty product. However, the Supernatural Radiance Serum SPF 30 is one known example that contains a soy-derived ingredient.

This is a key inconsistency. While the brand promotes a general soy-free image, product formulation details can differ. It is important for consumers to recognize that a brand's overall claim may not apply universally to every single item in their collection.

RMS Beauty prides itself on transparency and lists all ingredients on their packaging and website. Third-party sites like INCIDecoder can also be helpful for cross-referencing.

You should look for any form of soy, including Glycine Soja (Soybean) Oil, soy lecithin, or other soy-derived ingredients. Always read the inactive ingredients section carefully.

While the brand claims its general product line is soy-free, and resources like SkinSAFE rate some products free of common allergens, the most reliable method for those with allergies is to check the specific ingredient list on the product packaging at the time of purchase.

The safest approach is to assume that not all products are soy-free and to meticulously read every ingredient label. If you are unsure or have a severe allergy, it may be best to avoid the brand or contact them directly for specific product information.
