The Gentle Solution to Wrinkles
DESCRIPTION: Citric acid is one of the most common organic acids and occurs in the metabolism of almost all living things.
HISTORY: In 1784, the German-Swedish chemist Carl Wilhelm Scheele was the first to isolate citric acid from lemon juice, hence the name ‘citric acid’. However, there is a theory that citric acid was discovered in the 9th century by a Persian alchemist named Jābir ibn Hayyān.
EFFECT: Citric acid is a weak organic acid that is popular due to be a natural preservative and conservative. Topical acidic treatments can brighten skin, shrink pores, treat mild acne and correct dark spots and fine lines. These acids can be applied to skin in the form of masks, scrubs, toners or peels. In cosmetics, citric acid has an astringent, keratolytic and naturally lightening effect. When applied to skin, citric acid can slough off dead skin cells and speed new cell turnover. The latter promotes new skin growth that can help alleviate the appearance of age spots, acne scars, small wrinkles and areas of uneven tone and texture. It also helps accelerate cell regeneration and reduces the depth of wrinkles.
