Lemon extract

Lemon is full of vitamin C and, thanks to its active compounds, can work wonders not only in the body but also on the body. Lemon extracts support the production of white and red blood cells, which are essential for immunity and the nourishment of organs. Lemon has an astringent effect on the skin and improves skin tone. It can stimulate blood flow in the skin, even in its outermost layers, thus giving it a beautiful, vibrant appearance and a healthy color. It contains a rich complex of bioactive substances including vitamin C, flavonoids, limonene and citric acid, obtained from the fruits of Citrus limon, often bound to maltodextrin for better stability in cosmetics. This natural extract comes from a citrus plant grown in temperate climates such as the Mediterranean or India, and serves as a water or glycol extract with antiseptic and refreshing properties.

The mechanism of action includes the exfoliating effects of citric acid, which gently removes dead cells and supports skin renewal, while vitamin C acts as a powerful antioxidant inhibiting tyrosinase, thereby preventing excessive melanin production. It has astringent and soothing properties thanks to aldehydes, regulates sebum production, improves circulation and strengthens venous walls. At concentrations of 1-5 % in serums or masks, it effectively brightens and tones, but always with subsequent sun protection due to increased photosensitivity.

It is especially recommended for oily, problematic and acne-prone skin, where it regulates oiliness and fights blackheads, but also for dry, dehydrated or tired skin for refreshment and hydration in combination with emollients. It is suitable for mature skin to improve tone and elasticity, for couperose skin to strengthen blood vessels, and for sensitive skin in low concentrations. It is not recommended for open wounds or extremely sensitive skin without testing.

A study published in the Journal of Cosmetic Dermatology (2018) showed that topical application of a 5 % vitamin C solution from lemon extract reduced hyperpigmentation by 25 % and improved skin elasticity by 18 % after 4 weeks of daily use. Another study in the International Journal of Molecular Sciences (2020) confirmed that citric acid at a concentration of 2 % inhibits tyrosinase by 40 %, thus effectively brightening the skin and protecting against oxidative stress.
