What is zinc oxide and why is it used in cosmetics and healthcare?
Zinc oxide is a natural mineral compound widely used in dermatology, cosmetics and pharmaceuticals for its protective, purifying and soothing properties. Known for its antibacterial and anti-inflammatory action, it is particularly prized for the care of sensitive, irritated or blemish-prone skin.
Present in many sun protection products, healing creams and baby ointments, it forms a protective barrier against external aggression while promoting skin regeneration.
What are the benefits of zinc oxide for the skin?
Zinc oxide is an essential ingredient for treating and protecting the skin, thanks to its many virtues:
Why is zinc oxide used in sun creams?
Zinc oxide is one of the best mineral filters for protecting skin from ultraviolet rays. Unlike chemical filters, which absorb UV rays and can cause allergic reactions, zinc oxide forms a physical barrier that reflects sunlight.
It is particularly recommended for :
Sensitive and reactive skin.
Babies and children, as it is safe and non-irritating.
Skin prone to sun allergies.
Fans of natural cosmetics, as it is biodegradable and environmentally friendly.
Is zinc oxide effective against acne?
Yes, zinc oxide is an excellent natural remedy for acne, thanks to several complementary actions:
It reduces inflammation, soothing painful redness and pimples.
It dries out blemishes, promoting their rapid disappearance.
It regulates sebum production, preventing the appearance of new pimples.
It limits bacterial proliferation, responsible for inflammatory acne.
It can be found in anti-acne creams, mattifying powders and purifying skincare products to help restore clear, balanced skin.
Why is zinc oxide used in baby care products?
Zinc oxide is a key ingredient in baby ointments, particularly those designed to treat diaper rash. It works by forming a protective barrier that :
Insulates the skin from moisture and diaper friction.
Soothes irritation and redness, limiting skin inflammation.
Promotes healing in sensitive areas.
Its gentle, non-aggressive efficacy makes it an essential ally in protecting the fragile skin of infants.
Is zinc oxide suitable for sensitive skin?
Yes, zinc oxide is ideal for sensitive and reactive skin. It is often recommended for :
Skin prone to redness and irritation (eczema, rosacea).
Skin intolerant to chemical sunscreens.
Fragile skin of babies and the elderly.
Thanks to its anti-inflammatory and protective properties, it helps soothe and strengthen fragile epidermis.
Can zinc oxide be used in make-up?
Absolutely! Zinc oxide is present in many foundations, powders and BB creams thanks to its properties:
Matifying, ideal for oily or shine-prone skin.
Covering, to mask imperfections and redness.
Protective, thanks to its UV filtering action.
It's an essential ingredient in natural and organic cosmetics, often used as an alternative to silicones and other occlusive agents.
Does zinc oxide present any risks or contraindications?
Zinc oxide is generally well tolerated, but a few precautions should be taken:
It can be slightly drying, especially on very dry skin.
As a loose powder, it should not be inhaled, as it can be irritating to the respiratory tract.
Zinc oxide nanoparticles are controversial, as they can penetrate deeper into the skin. It is therefore preferable to choose nanoparticle-free products.
