Glossary
A concentrated preparation of plant-derived compounds obtained by soaking plant material in a solvent (water, alcohol, oil, or glycerin) to extract its active components. Botanical extracts appear in skincare as antioxidants, anti-inflammatories, colorants, and fragrance ingredients.
A botanical extract is a concentrated preparation of a plant's active compounds, separated from the bulk plant material through a solvent-based extraction process. The goal is to capture the specific bioactive molecules (polyphenols, flavonoids, terpenes, alkaloids, vitamins) while leaving behind the fibrous structural material of the plant. The result is a concentrated ingredient that delivers the plant's beneficial properties at much higher levels than the whole plant could provide topically.
Water extraction (decoction, infusion) produces hydrosols and aqueous extracts, capturing water-soluble compounds. Alcohol extraction (tinctures) is more effective at dissolving a broader range of compounds including those that are not water-soluble. Oil infusion captures fat-soluble compounds and produces botanical oils used directly in skincare. CO2 extraction uses pressurized carbon dioxide as a solvent, producing very pure extracts without solvent residues. Each method captures a different spectrum of the plant's chemistry.
Chamomile extract (Matricaria chamomilla): anti-inflammatory bisabolol and apigenin for soothing sensitive skin. Green tea extract (Camellia sinensis): catechin polyphenols providing potent antioxidant protection. Calendula extract (Calendula officinalis): triterpene anti-inflammatory and wound-healing compounds. Licorice root extract (Glycyrrhiza glabra): glabridin for skin brightening and anti-inflammatory activity. Centella asiatica (cica): asiaticoside and madecassoside for barrier repair and collagen stimulation.
Not all botanical extracts are effective at the concentrations used in commercial products. A product listing an extract at the end of its ingredient list (indicating a very low concentration) may contain too little to provide meaningful benefits. Effective botanical ingredients appear higher in the ingredient list and are used at concentrations supported by clinical evidence.
Most botanical extracts used in skincare have long safety histories. However, concentrated plant compounds can cause allergic reactions, photosensitivity, or irritation in some individuals. Always patch test new products containing botanical extracts you have not used before, especially if you have sensitive skin.
Check where it appears in the ingredient list (higher = more concentrated). Look for specific, named compounds rather than vague 'proprietary blends.' Research whether the specific botanical has clinical evidence supporting its claimed benefits at cosmetic-use concentrations.
