What are the benefits of zinc for the skin?

Zinc ensures the proper functioning of the immune and nervous systems. It also promotes growth. Beyond these benefits, this trace element possesses other properties beneficial to the skin. It combats excess sebum and stimulates the regeneration of skin cells. At Typology, we have developed several skin care products containing zinc.

The essentials to know about zinc.

Zinc is a metallic particle, symbolised as "Zn" and holds the atomic number 30 in the periodic table of elements. In metallurgy, it is a component of brass (zinc and copper), but it is also present in the human body, albeit in small quantities (around 2 to 3g), distributed in the muscles, bones, liver and skin. It is a trace element, that is to say a component essential for the proper functioning of the body. Zinc plays a role in DNA synthesis, ensures the production of certain proteins and contributes to the balance of cognitive functions.A deficiency in zinc would exacerbate inflammatory phenomena.

It should be noted, this trace element cannot be stored by the body. Therefore, to reap its benefits, regular consumption of zinc-rich foods is essential. The food richest in zinc is the oyster, but there are others such as the offal, red meat, wholemeal bread and eggs.

When applied topically, zinc provides several benefits to the skin.It is included in the composition of certain skin care products in various forms such as zinc oxide, zinc gluconate, or even zinc PCA.

The cosmetic properties of zinc.

When applied topically, zinc possesses several properties that are essential for skin health.

  • Zinc, a comprehensive anti-spot active ingredient.

    Zinc is a trace element that possessesanti-inflammatory, antibacterial and healing propertiesthat are highly beneficial for acne. Indeed, it inhibits the growth of the bacteria responsible for acnePropionobacterium Acnes, which is the bacteria primarily involved in this skin condition. Furthermore, zinc reduces the activity of the sebaceous glands due to its anti-androgenic activity. Thus, it helps to regulate sebum production and therefore prevents blemishes.

  • Zinc, an effective UV filter when combined with oxygen.

    Zinc oxide is primarily aUV protective filter. It is used in sun creams, acting as a shield on the skin's surface. Indeed, it iseffective in blocking and deflecting UVA and UVB rays, thus protecting the skin from the harmful effects of the sun.

    Beware, in some products, it may be of nanometric size. The health risks are as follows: psuspected percutaneous penetration, suspected reproductive toxicity, suspected genotoxicity, suspected carcinogenicity. Furthermore, regarding the environment, there is also suspected aquatic ecotoxicity. Despite this, this UV filter remains bio-compatible according to the COSMOS standard.

    At Typology, we apply the precautionary principle and exclude nanoparticles from our formulas. Our sun cream for the face with SPF50 and aloe vera contains non-nanometric zinc oxide.

    However, it is important to clarify that whether zinc oxide is nano or not, exposure to high concentrations of this mineral compound is likely to cause a respiratory tract inflammation as well as lung problems. For this reason, the European regulation has banned the presence of zinc oxide (nano or not) in spray formulas since 24th February 2018.

    Furthermore, zinc oxide is listed in ANNEX VI of the European regulation that governs UV filters. Whether it is nanometric or not, its maximum permitted concentration as a UV filter is 25%.

  • Zinc, an anti-microbial agent.

    Thanks to its antimicrobial action, it is also found in toothpastes (anti-plaque properties) as well as deodorants and antiperspirants. Moreover, it is also effective in sanitising oily scalps and thus limiting the appearance of greasy dandruff.

The role of zinc in Typology skincare.

At Typology, we use zinc derived from beetroot. It is then combined with L-PCA. The latter is a physiological vector, that is, an active ingredient that facilitates the assimilation of zinc by skin cells.

To take advantage of the properties of zinc for your skin and scalp, you can select one of our treatments.

  • Thepurifying cleansing gelcontains 2% zinc PCA combined with bamboo extract. Bamboo naturally contains porous particles that absorb excess sebum on the skin. This high absorption capacity contributes to reducing skin shine. Therefore, this compound is particularly recommended for combination to oily skin types.

  • Specifically designed for oily skin, thematifying serumis concentrated in zinc PCA, azelaic acid (10%) of plant origin, and organic bamboo extract to reduce excess sebum. Of plant origin, azelaic acid is known for its anti-comedogenic and anti-bacterial effects. Indeed, this molecule works to unclog pores and reduce the formation of "open" comedones (otherwise known as blackheads). It also helps to combat the bacteria involved in acne.

  • Due to its content of sebum-regulating and antibacterial actives, ourpurifying face creammade with 4% zinc PCA and bamboo extract is ideal for moderating sebum secretion, refining skin texture and preventing the appearance of unsightly blackheads. It should be applied daily to clean, dry skin and over yourface serum, using small circular movements during application until the cream is fully absorbed. However, this cream is not recommended for pregnant and breastfeeding women due to the essential oils it contains.

  • Formulated without talc, silicones and nanoparticles, our translucent mattifying loose powder specifically targets shiny and oily skin. A true hybrid product between skincare and makeup, it contains up to 1% of zinc PCA. This element helps to absorb excess sebum for an immediate and lasting matte finish, thus helping to extend the wear of tinted treatments. It also includes 0.1% ofhyaluronic acid (INCI name: Sodium Hyaluronate): this hygroscopic compound can hold up to 1,000 times its weight in water, making it a powerful skin care ingredient for instant hydration.

  • The local blemish serum contains 2% salicylic acid and 1% zinc, for a anti-bacterial and purifying overall action. It is typically used as a treatment, over a limited period of time, in local application: a single drop is enough for an isolated spot.
