Laminaria Ochroleuca (Kelp) Extract
A type of kelp that helps soothe skin and offers hydration-enhancing properties, it can also play a role in reinforcing skin’s barrier and warding off environmental stressors. Researchers note that this ingredient is particularly useful for those prone to sensitive skin. It is in the class of Algae Extract which also include ahnfeltia concinna extract, alaria esculenta extract, algae exopolysaccharides, algin, alteromonas ferment extract, alteromonas ferment extract, ascophyllum nodosum extract, asparagopsis armata extract, chlorella protothecoides, chlorella vulgaris extract, dunaliella salina (green algae) extract, hydrolyzed f-fucoidan, macrocystis pyrifera (kelp) extract, and marine extract.
L-Ascorbic Acid
Part of the Vitamin C family of ingredients, L-ascorbic acid is Vitamin C in its purest form, and the active form required by the body to result in the many skin skin benefits of Vitamin C. The issue with L-ascorbic acid is in the delivery, as it is very unstable in water, and needs a pH 4 or below for it to penetrate the skin. That being said, when it can be stabilised in a formula and is able to penetrate the skin, it provides the highest potency of any form of Vitamin C currently available. Vitamin C can also be found on ingredients lists as ascorbic acid, ascorbyl glucoside, ascorbyl palmitate, ethyl ascorbic acid, magnesium ascorbyl phosphate, sodium ascorbyl phosphate and tetrahexyldecyl ascorbate.
Carnitine is a naturally occurring amino acid derivative found in the body. In skincare, L-Carnitine is used for its potential skin-soothing, antioxidant, and revitalizing properties.
Lecithin
Lecithin can be classed as a phospholipid, which occurs naturally in eggs, soybean, sunflower oil and corn. It contains a high concentration of fatty acids, which support the skin’s natural barrier by creating a lipid film to prevent transepidermal water loss (TEWL). Lecithin also has lipophilic & hydrophilic properties, meaning it can function as an emulsifier and skin penetration-enhancer, helping to deliver actives deeper into the skin. Lecithin is in the class of essential lipids, and can be found on ingredient lists as caprooyl phytosphingosine, caprooyl sphingosine, cholesterol, glycolipids, glycoproteins, glycosphingolipids, linoleic acid, linolenic acid, phospholipids and phytosphingosine.
Leucine
Leucine is an amino acid that has anti-aging properties. It is used in anti-aging skin care products and is thought to help regenerate aging skin and reduce fine lines and sagging skin. It is said to create firmer, more supple skin and increase elasticity by repairing aging skin tissue. Amino acids are a class of ingredients. They can also be found on ingredients lists as acetyl glucosamine,acetyl tyrosinamide, alanine, arginine hcl, arginine pca, histidine, isoleucine, lysine, phenylalanine, proline, serine, taurine, threonine and valine and yeast amino acids.
Licochalcone A is a naturally occurring compound found in the root extract of the licorice plant (Glycyrrhiza glabra). It is used in skincare for its potential anti-inflammatory, antioxidant, and skin-soothing properties.
Glycyrrhiza Glabra (Licorice) Root Extract
It has been shown to prevent and reverse UV-induced skin damage, to provide visible skin-lightening properties to the skin. Its second active component, glycyrrhetinic acid is used in skincare for its anti-inflammatory benefits. It works by inhibiting the production of inflammatory substances, such as cortisone, within the body, with some research showing results to be comparable to prescription hydrocortisone cream. Licorice is a family of ingredients and can also be known as ammonium glycyrrhizate, dipotassium glycyrrhizate (licorice), glycyrrhetinic acid, glycyrrhiza glabra (licorice) root extract, glycyrrhiza glabra root extract or glycyrrhiza inflata root extract.
Lilium Candidum Flower Extract
Lily extract is derived from various species of lilies, particularly Lilium candidum (also known as Madonna lily) or Lilium longiflorum. In skincare, lily extract is used for its potential skin-soothing, moisturizing, and brightening properties.
Linoleic Acid
Linoleic Acid is an Omega 6 essential fatty acid (EFA), found in many plant oils: corn, safflower & sunflower. Linoleic acid forms the fatty acid based of Ceramides EOH, EOS and EOP, which are essential for the normal functioning of the skin barrier. Applying linoleic acid topically helps to support ceramide functioning within the skin, leading to improved skin hydration and smoothness. Research also shows that sebum in acne-prone skin can be lacking in Omega 6 (with too much Omega 3), so there is evidence to suggest applying this topically can help to balance the sebum composition and in turn reduce acne lesions. Linoleic Acid is in the class of essential lipids, and can be found on ingredient lists as caprooyl phytosphingosine, caprooyl sphingosine, cholesterol, glycolipids, glycoproteins, glycosphingolipids, Lecithin, linolenic acid, phospholipids and phytosphingosine.
Linolenic Acid
Alpha Linolenic Acid (ALA) is a plant-based Omega 3 fatty acid, found in plant oils such as flaxseed and soy. ALA provides anti-inflammatory effects by inhibiting the production of inflammatory mediators in the body. ALA also supports healthy skin barrier functioning, by inhibiting levels of trans-epidermal water loss (TEWL), and therefore maintaining adequate levels of hydration in the epidermis, resulting in smooth, soft & moisturised skin. Linolenic acid is in the class of essential lipids, and can be found on ingredient lists as caprooyl phytosphingosine, caprooyl sphingosine, cholesterol, glycolipids, glycoproteins, glycosphingolipids, Lecithin, linoleic acid, phospholipids and phytosphingosine.
liquorice extract
loofah extract
Luffa Cylindrica Extract, also known as sponge gourd or loofah, is derived from the fruit of the Luffa cylindrica plant. In skincare, this extract is used for its potential exfoliating, cleansing, and skin-smoothing properties.
Lysine
Lysine is an amino acid that helps build collagen in the skin and will therefore help treat fine lines, wrinkles and sagging skin. Amino acids are a class of ingredients. They can also be found on ingredients lists as acetyl glucosamine,acetyl tyrosinamide, alanine, arginine hcl, arginine pca, histidine, isoleucine, leucine, phenylalanine, proline, serine, taurine, threonine and valine and yeast amino acids.
Macrocystis Pyrifera (Kelp) Extract
Macrocystis pyrifera extract is a type of seaweed rich in multiple beneficial ingredients. Its primary value in skin care comes from its antioxidant properties. It is in the class of Algae Extract which also include ahnfeltia concinna extract, alaria esculenta extract, algae exopolysaccharides, algin, alteromonas ferment extract, alteromonas ferment extract, ascophyllum nodosum extract, asparagopsis armata extract, chlorella protothecoides, chlorella vulgaris extract, dunaliella salina (green algae) extract, hydrolyzed f-fucoidan, laminaria ochroleuca (kelp) extract, and marine extract.
