L-Ascorbic Acid

Many forms of vitamin C are unstable which can result in products losing their efficacy over time. Vitamin C is a powerful antioxidant, aids collagen synthesis, improves skin tone, and also has a brightening effect. L-ascorbic acid is a stable form of vitamin C. It usually comes in the form of a powder which is then combined with other serums before applying to the skin. For best results, apply in the morning as this is when vitamin C can work its magic, protecting your skin from UV rays, pollutants and other stressors.

Lactic Acid

Lactic acid is an alpha hydroxy acid that gently exfoliates the skin by melting the intercellular glue that binds cells together allowing the dead skin cells to easily shed. It comes from milk and is the softest out of all of the acids.It is also a humectant, which means it attracts water to the skin, giving it hydrating properties. Lactic acid has a larger molecular size than glycolic and is not able to penetrate as deeply so it’s less irritating and more suitable for sensitive and dry skin types. Lactic acid is naturally produced by the body so there is a low chance of a reaction.

Lanolin

Lanolin is a wax sourced from the sebaceous glands of woolly animals such as sheep, goats, camels and rabbits. Lanolin is an emollient and creates a barrier on the skin, trapping hydration and preventing dryness. As lanolin is sourced from animals, there is a danger of toxicity if the animals have been sprayed or treated with pesticides.

Lavender Essential Oil

Lecithin

Lecithin is a fat found in cells. In skincare it’s a bit of an all-rounder - it is used as an emollient to assist moisture retention and as a penetration enhancer- it can deeply penetrate into the skin and can carry other ingredients with it. It can also be used to emulsify ingredients that usually wouldn't combine.

LED

LED light therapy is a non invasive treatment that harnesses specific wavelengths of light to treat a multitude of skin conditions as well as promoting healthy skin function. Clinically proven wavelengths of light promote a natural response in the skin known as photobiomodulation- a similar process to photosynthesis in plants. These wavelengths are absorbed by skin receptions that convert the light into celluar energy, resulting in better skin function and faster renewal. LED light also has regenerative, anti-bacterial and anti-inflammatory properties. At Pfeffer Sal, we use the Dermalux LED devices which are registered as a CE medical device. 

Lemongrass Oil

Lemongrass oil is derived from the lemongrass plant and is known for its antiseptic and astringent properties. It is used to control oil production and to kill bacteria making it a great ingredient for acne and oily prone skin.

Lipid Barrier

The lipid barrier is a part of the epidermis. It is a protective layer that consists of fatty cells like cholesterol, fatty acids and triglycerides. Its main function is to protect the skin from external aggressors and prevent excess water loss (known as transepidermal water loss) from skin layers.

Liquorice Root Extract

Used in traditional Chinese medicine for centuries, liquorice root has been proven to be a powerful anti-inflammatory which is fantastic for calming and soothing irritated skin. It is particularly beneficial for conditions such as rosacea and psoriasis

Lycopene

Lycopene is a natural pigment that is responsible for fruit and vegetables’ red colour. It’s a potent antioxidant that protects skin from free radical damage from UV rays, pollutants and other environmental stressors. Internal sources of lycopene include tomatoes and watermelon.

Lymphatic Drainage Massage
