Tested for you: Setting Spray „Boost“ from Beautyblender

Boost 4-in-1 Firming Peptide Setting Spray sounds promising, but what is it exactly? It is a multitasking spray that sets makeup for up to 18 hours. In the process, it is supposed to plump up the skin, make pores disappear and reduce an unsightly shine. Micro-powders are at work as pore refiners and against shine. Peptides and mimosa flower extract are said to make the skin appear firmer in the long term. Caffeine helps the complexion feel more invigorated and soft. Setting spray with peptides And what about the peptides, which are already promised in the product name. These tiny molecules are particularly powerful and help to reduce the appearance of wrinkles, fine lines, discoloration, as well as loss of firmness. According to the chemical definition, peptides are smaller proteins. Their building blocks are several amino acids linked by peptide bonds. This is where the name comes from. Peptides have numerous functions in nature – some act as messengers in plants, others are hormones in the human body. In the skin, peptides can strengthen the cells by ensuring that the proteins can better develop their effect. At the same time, UV rays, pollutants and bacteria are kept away. Because peptides stimulate the production of collagen, the skin looks firmer and younger over time. My spray test The spray from the pink bottle does not need to be shaken, but is already ready for use. I close the eyelids so that nothing gets into the eyes when spraying. If so, wash out immediately with clean water! The setting spray smells delicately of mimosa and lays weightlessly on my skin. In fact, I think I feel an immediate slightly tightening surface effect as soon as the evaporation of the liquid begins. The skin feels plump and supple. The makeup or whatever color you wear on your skin stays in place all day long. I also use Boost over my tinted sunscreen, which otherwise likes to shine a bit. Nothing at all smudges with the Setting Spray, as the texture is moisture resistant and waterproof. In addition, vegan, free of animal testing, oil- and gluten-free. „Boost“ from Beautyblender, 100 ml, 40 Euro… weiterlesen

What Exactly Are Peptides?

Written by Margit Rüdiger on . No Comments on What Exactly Are Peptides?

The term peptides is used time and again in skin care products. If you believe the advertising, true power molecules are hidden behind it, which smooth wrinkles, tighten and refresh the skin. And they also make the muscles grow. “First and foremost, peptides help to form the collagen and elastin fibers that are everywhere in our skin. It’s short chains of amino acids that tell the body to produce more collagen.” This is how Ron Robinson, my favorite cosmetic chemist in New York, who has an answer to every beauty question, explains the phenomenon of peptides. Roger that. Peptides are something like little messengers that deliver messages. Roger that. In this case, they signal the cells to start the skin’s natural regeneration process.But why are there so many different peptides? Robinson has an explanation for that too. „Since peptides are composed of up to 50 amino acids, they are incredibly changeable. All you have to do is add, remove or replace an amino acid and you have already created a new peptide that again fulfills new functions.“ This can be smoothing or strengthening, it can have an anti-inflammatory effect or keep the moisture in the skin for longer. Chain reaction To go a little deeper: Proteins such as collagen consist of chains of peptides, which in turn consist of amino acids. There are hundreds of peptides, and each peptide is made from a combination of amino acids. If peptides are combined in a certain way, they form proteins. Proteins in turn are composed of one or more polypeptide chains. The length of these chains can vary from approx. 40 to over 4,000 amino acids. To speak of the one peptide would be wrong. Peptides are rather a whole group with a wide variety of tasks and functions. Of the many peptides, tetrapeptides (they have four amino acids) and hexapeptides with six amino acids are often used in skin care. Due to their special chemical structure, both perform a wide variety of tasks: Hexapeptides can reduce stubborn expression lines, while tetrapeptides promote elasticity and firmness of the skin. Molecules which have at least ten amino acids are generally classified as polypeptides. Shorter polypeptides are called oligopeptides. The individual amino acids are linked by so-called peptide bonds. Incidentally, this was researched in 1902 by the German chemist and later Nobel laureate Emil Fischer. Peptides instead of botox Agireline (INCI name: Acetyl-Hexapeptide 3), which is said to have a botox-like effect, is one of the best known oligo- or hexapeptides.… weiterlesen
