These are the cosmetic ingredients that do work, say the experts


There are so many cosmetic ingredients that we sometimes wonder which ones to choose. Dermatologists are clear: Those who present proven scientific evidence. We have spoken with several experts and here is the list of the essential ones:

Titanium dioxide and zinc oxide

Are particles that act as physical or mineral filters and they act by reflecting the sun’s rays and preventing them from entering our skin. Titanium dioxide blocks UVB and UVA better and zinc oxide, infrared. Both are safe and do not irritate the skin.

Vitamin C

His more potent and antioxidant version is ascorbic acideither. In addition to protecting against oxidation, Dr. Carlos Suárez, a dermatologist at the Clínica Sánchez del Río (Oviedo-Asturias), affirms that “it has demonstrated its depigmenting efficacy and a repairing action against sun damage”, which leads to a notable improvement in the luminosity of the skin. The main problem with vitamin C is its instability, which makes it easily oxidized, “which is why it is essential to select the right product that penetrates the skin in its active form,” recommends the doctor.

ferulic acid

It is an antioxidant of plant origin that belongs to the group of hydroxycinnamic acids. It has anti-inflammatory, depigmenting and regenerative properties, and protects from oxidative stress. In addition, it provides stability to vitamin C, which is why it is common to see them together in formulas.

Hyaluronic acid

It is an essential component of our skin. When its concentration decreases, the skin wrinkles and relaxes. There is High molecular weight HA that acts on the surface, filling and moisturizing the skin. The low molecular weight HA penetrates, acting in depth and causing a filling effect from within.

ceramides

Postbiotic assets

It is a very new scientific term. They are substances (enzymes, proteins, lipids, sugars) that produce probiotics (by fermentation) with a beneficial action on our immunity or metabolism”, explains Isabel González Pastor, who states that “there are already studies that show how they balance and maintain the skin’s barrier function”.

Glycolic Acid

It is the most prominent of the alpha hydroxy acids (AHA) and comes from sugar cane, although there are also others such as mandelic (almonds) or lactic (milk). “They have an exfoliating effect that makes the skin brighter, improves superficial wrinkles and blemishes, and evens out skin tone,” explains dermatologist Carlos Suárez.

Retinoic acid

This active ingredient in its pure state, also called tretinoin, comes from vitamin A and is, in the words of Dr. Suárez “the most effective anti-aging active principle”. But if we have very sensitive skin, it can irritate us excessively, so “in cosmetics it is more common to find less effective derivatives such as retinol or retinaldehyde (also known as retinal) that are better tolerated,” says Dr. Suárez. Dr. Lola Conejo-Mir, a member of GEDET, agrees: “Of the anti-aging active ingredients, retinol is the king: it stimulates the formation of collagen in the skin, combats wrinkles and improves dark spots…”. For sensitive skin, the doctor proposes “other alternatives that can help us achieve the same effect as retinol without irritating, such as bakuchiol, of plant origin, azelaic acid, or alpha hydroxy acids such as glycolic acid”.

Bakuchiol

It is a trend in cosmetics. It’s about a vegetable ingredient that comes from the plant known as Babchi (Psoralea corylifolia). It is considered the natural alternative to retinol because it is an anti-aging active ingredient that stimulates collagen in the skin, like it, but with the advantage of not irritating or being photosensitive. Other effects? Reduces wrinkles, unifies skin tone, is sebum-regulating and anti-inflammatory.

azelaic acid

Introduceresults similar to retinol (evens skin tone, reduces spots, improves luminosity…), and it is an alternative for sensitive skin that does not tolerate it. In addition, it is sebum-regulating and antibacterial, so it works very well on oily skin.

growth factors

Dr. Truchuelo highlights them within the group of skin stimulators. And Isabel González Pastor, co-founder of Mila Bonis, says that these active ingredients, which reactivate the skin’s own rejuvenating mechanisms, “are at the top of the beauty pyramid of a true pro.” The Growth factors are molecules, mainly proteins, which is present in our body, but can also be obtained from nature. “New technologies allow the synthesis of these factors that seek to imitate the actions of the young skin’s own molecules”, explains Dr. Truchuelo, who gives as an example “the new formulation technologies of Cryptomphalus aspersa or the epidermal growth factor”. The different types of growth factors have shown efficacy in “reducing wrinkles, recovering the capacity to produce collagen and hyaluronic acid, protecting the skin barrier and improving elasticity and appearance of all skin types”, lists Isabel González Pastor.

Peptides

Are chains made up of amino acids and, depending on the number of these, they receive a name (oligopeptide, polypeptide, hexapeptide…) and perform certain functions. They are present in our body and also (synthetic) in our cosmetics. They work by sending signals to the skin to regenerate, calm down, synthesize collagen and elastin… To be effective they must be combined with other active ingredients such as antioxidants, hyaluronic acid or alpha hydroxy acids.
