Ingredients

Antioxidants protect the skin and the formula itself from oxidative damage. In skincare, antioxidants serve a dual purpose: 1. For the skin: They neutralize free radicals caused by UV exposure and pollution, helping to prevent premature aging, dullness, and support skin health. 2. For the formula: They stabilize other ingredients (like oils and active compounds) by preventing them from breaking down and oxidizing, thereby maintaining the product's potency, color, and scent over time.

Astringent ingredients produce a temporary tightening or toning sensation on the skin by causing a mild contraction of the skin's proteins. This function can help refine the appearance of pores and reduce excess surface oil, providing a smooth, mattified finish.

Buffering ingredients or a system of ingredients are used to adjust and stabilize the pH level of a product. Buffering agents help maintain the product within an optimal, skin- and formula-friendly pH range, ensuring both the comfort of the skin upon application and the stability and effectiveness of the active ingredients in the formula.

Chelating agents bind to and deactivate metal ions (like calcium and iron) in water or within a formula. This prevents these minerals from destabilizing the product, causing discoloration, or reducing the efficacy of other ingredients.

Emollients soften, smooth, and condition the skin's surface by filling in the gaps between skin cells. Emollients improve the skin's texture and flexibility, creating a smooth, supple feel and helping to reinforce the skin's natural barrier.

Emulsifying ingredients allow two normally immiscible substances – typically oil and water – to combine into a stable, uniform mixture (an emulsion). Emulsifiers work by reducing surface tension, preventing the phases from separating.

Emulsion stabilising ingredients help maintain the long-term stability and uniform texture of an emulsion (a mixture of oil and water). While emulsifiers are responsible for the initial blend, stabilizers work to prevent the mixture from separating over time.

Fragrance is an ingredient (or blend of ingredients) added to a formula primarily to provide a specific scent. In skincare, fragrances can be derived from natural essential oils or created synthetically. At Lumessentials, we formulate for skin health first. We use only minimal, skin-safe natural fragrance components where absolutely necessary for product integrity.

An ingredient that creates a semi-solid, cohesive network within a liquid, giving the formula a distinct gel-like texture and structure. This function provides unique sensory properties, such as a smooth, non-greasy application and a fresh, lightweight feel.

Humectants attract and bind moisture from the air and from the deeper layers of the skin, drawing it to the skin's surface. Humectants work by increasing the water content of the top layer of the skin (the stratum corneum), resulting in improved hydration, a plumped appearance, and a softer feel.

Occlusives form a protective, hydrophobic (water-repelling) layer on the skin's surface. This physical barrier primarily functions to slow down transepidermal water loss (TEWL), helping to seal in hydration and support the skin's natural moisture barrier.

An ingredient or system that establishes, adjusts, and maintains a product's acidity or alkalinity (pH) to an optimal, stable level. This ensures formula stability and efficacy, as well as skin compatibility.

Preservatives prevent the growth of harmful microorganisms (like bacteria, mold, and yeast) in a product. This function is critical for ensuring the product remains safe, stable, and effective throughout its shelf life and during consumer use.

Skin conditioning ingredients are a broad functional category that improves the overall appearance, texture, and feel of the skin by enhancing its suppleness, smoothness, and softness.

Solvents are typically liquids used to dissolve or uniformly disperse other substances within a formula. Solvents are fundamental to the creation process, as they ensure the even distribution and stability of active compounds, oils, waxes, and preservatives.

Surfactants lower the surface tension between two substances, such as oil and water. The specific function of a surfactant depends on its molecular structure and application, including cleansing and emulsifying.

Viscosity controlling ingredients control the thickness of the product. Some ingredients make a product thicker (like a rich cream). Others keep it thin (like a lightweight serum).
