Why skin spots occur and how to treat them

An even skin tone is usually associated with healthy skin. In contrast, skin subject to premature aging caused by UV light (photoaging) experiences an increase in the production of melanin, the pigment controlling skin colour. And this results in the appearance of skin spots.   History and origins In ancient Egypt, as well as in…

Ingredientes para la formulación de protectores solares

Sunscreens

What are the effects of sunlight on skin? Visible sunlight covers the wavelengths from 400 to 780 nm, and is a small part of the entire spectrum of radiation emitted by the sun. So-called infrared radiation corresponds to wavelengths longer than 780 nm, while ultraviolet radiation is defined as having a wavelength shorter than 400…

tensioactivos sostenibles: alquilpoliglucósidos

Sustainable surfactants

Sustainability is about promoting economic and social progress while respecting natural ecosystems and the quality of environment. The consumption of products whose raw materials come from renewable or natural sources, and which are readily biodegradable, is commonplace. Alkylpolyglucosides (APG) are sustainable surfactants that meet these characteristics and are suitable for the EU-Ecolabel. Alkylpolyglucosides (APGs): the…

Antioxidante protector del sol

Ferulic Acid, the sun-protective antioxidant

Prolonged exposure to ultraviolet rays is the major cause of skin damage, leading to injury and premature aging. Photons from solar radiation activate a chain reaction that leads to the interaction of free radicals with proteins and lipids. In cosmetics several strategies are followed to fight against the damage produced by solar radiation, one of…

cosméticos naturales

Natural cosmetics

In the formulation of cosmetics, it is very common to use ingredients of recognized efficiency obtained by chemical synthesis. Many of these ingredients are also found in vegetables, and with the substitution of synthetic components by those of vegetable origin, it is possible to “naturalize” cosmetics, and achieve a higher percentage of ingredients of renewable…
