Zinc is an essential trace element involved in many enzymatic reactions in the body. It is naturally present in the skin and plays a documented role in maintaining its balance.
Authorized health claims (EU Regulation 432/2012): zinc contributes to the maintenance of normal skin; zinc contributes to the maintenance of normal hair; zinc contributes to the maintenance of normal nails; zinc contributes to normal collagen synthesis for the normal function of the skin. These claims are authorized when the daily intake provides at least 15% of the NRV.
In scientific literature, zinc is also documented for its role in regulating the activity of certain enzymes involved in sebum metabolism, notably 5-alpha-reductase, an enzyme involved in converting testosterone to dihydrotestosterone (DHT). This modulation is linked, according to available data, to the appearance of blemishes and the visible reduction of shine on combination or blemish-prone skin.
Zinc is associated, according to available data, with documented soothing properties that contribute to skin comfort, resulting in skin that appears calmer and more comfortable.
It is also linked to supporting mechanisms involved in maintaining skin structure, consistent with the EFSA-authorized claim on normal collagen synthesis for normal skin function.
Its versatile profile and documented good tolerance make it an active ingredient suitable for formulas targeting blemish-prone skin as well as those supporting the visible quality of skin over time.
