Lemon water to give a healthy glow to dull skin?

A dull skin, lacking radiance and with imperfections can result from the accumulation of dead cells on its surface, when the skin's natural cell renewal lacks efficiency. The skin then becomes less smooth and does not reflect light properly, resulting in a less luminous complexion. Several factors can be responsible.

• Fatigue or lifestyle hygiene.

  When the body is weakened, due to fatigue or an unbalanced diet, it is not uncommon to observe a slowdown in various biological processes, including cellular renewal. The skin's desquamation becomes less efficient and dead cells accumulate on its surface.

• Pollution.

  The impurities that accumulate throughout the day on the skin can prevent it from "breathing" and mix with sweat, sebum or existing makeup, giving the skin a dull, greyish appearance.

• Inadequate cleansing of the skin.

  It is recommended to cleanse your skin once or twice a day depending on its type. This action will help to remove impurities present on its surface and will subsequently facilitate the application of other following treatments. We also advise you to carry out one or two exfoliations per week in order to remove dead cells and unclog pores.

Lemon water is a colourless liquid obtained by the condensation of water vapour in a still during the extraction of its essential oil. Although not as concentrated as the essential oil, lemon hydrosol still has several interesting properties for the skin and hair due to its composition. Lemon hydrosol has a characteristic scent common to all citrus derivatives. Fruity and refreshing, its aroma makes it a choice ingredient for perfumes and treatments. From a biochemical perspective, lemon hydrosol contains limonene, alpha and beta-pinenes, geranial, linalool and traces of vitamin C and flavonoids.

Please note : one should not confuse lemon juice and lemon hydrosol. The former is highly acidic and extremely photosensitising, due to its high concentration of furocoumarins. On the other hand, lemon water is a gentle treatment suitable even for pregnant or breastfeeding women and young children.

Several sources suggest that lemon water possesses intriguing properties, among them, the ability to provide a "healthy glow" effect. Indeed, lemon hydrosol is attributed with lightening and depigmenting effects. According to some sources, its application on the face could restore radiance and even out the complexion. However, it is important to note that to date, no scientific study has demonstrated a direct link between the application of lemon hydrosol and a brighter complexion.

In fact, the notion that lemon water is a complexion-enhancing ingredient stems from its composition. Indeed, it contains traces of vitamin C, a compound known for its brightening properties. Its mechanism of action is based on the inhibition of tyrosinase, an enzyme responsible for the conversion of the amino acid tyrosine into melanin. However, the amount of vitamin C contained in a lemon hydrosol is very low, and is probably insufficient to induce a real effect. Therefore, it is recommended to combine it with a treatment containing more vitamin C to achieve results.

To combat dull skin, you can also turn to active ingredients with keratolytic properties, such as glycolic acid. This fruit-derived exfoliant indeed helps to renew the skin surface, to restore its radiance. At Typology, we have incorporated it into our peeling mask. Applicable one to two evenings per week, it removes dead cells to unclog pores and refine the skin texture.
