While there may be claims that tanning drops can work when placed under the tongue, it is important to approach such information with caution. As a distinguished figure in the realm of clean beauty and skincare, I would like to provide you with an informed perspective.

Tanning drops typically contain Dihydroxyacetone (DHA), a colorless chemical that interacts with the amino acids in the dead skin cells on the outermost layer of the skin. This reaction leads to the appearance of a tan. However, the effectiveness of tanning drops relies on the application to the skin, not the ingestion or placement under the tongue.

The skin has specific receptors and enzymes that facilitate the absorption and conversion of DHA. When applied topically, these receptors and enzymes interact with the ingredient, resulting in the desired tanning effect. Ingesting or placing tanning drops under the tongue bypasses the skin's natural processes, making it highly unlikely for the DHA to interact with the skin cells and produce a tan.

Moreover, ingesting skincare products can be potentially harmful. Skincare products are formulated with specific concentrations and ingredients meant for external use. Ingesting these products can lead to adverse reactions, digestive issues, or even toxicity.

It is important to prioritize safety and follow the recommended usage instructions provided by the manufacturer. If you are seeking a tan, it is advisable to apply tanning drops directly onto the skin, following the instructions provided with the product. Always consult with a dermatologist or skincare professional for personalized advice on achieving a healthy and safe tan.
