How Molecular Weight Influences Skin Absorption
The skin's outer layer, the stratum corneum, serves as a natural Defense system, selectively allowing certain substances to pass through. Molecules with a lower molecular weight, like VOCs, have an easier time penetrating this barrier, while larger molecules are typically confined to the skin's surface. This explains why low molecular weight compounds found in many synthetic fragrances can be particularly concerning.
Essential Oils: Friend or Foe?
Not all VOCs are detrimental to skin health. Essential oils, for example, contain VOCs in the form of terpenes, which can offer a range of therapeutic benefits when used appropriately. Lavender essential oil, which contains compounds like linalool and linalyl acetate, is well-known for its calming and anti-inflammatory properties. In such cases, deeper skin penetration is beneficial, helping to soothe irritation and reduce redness. However, essential oils must be handled with care. When used in high concentrations or improperly formulated, they can cause sensitivity or irritation, particularly in those with sensitive skin. At Dr. Crazy, we meticulously formulate our products, using essential oils at concentrations designed to maximize their benefits while minimizing the risk of adverse reactions.
