FAQ about dietary supplements

Are dietary supplements used in cosmetics safe?

When taken as part of a balanced diet, cosmetic food supplements are safe, provided that the prescribed dosages are observed and a healthcare professional is consulted before commencing a course.

Which dietary supplements are most commonly used in cosmetics?

Dietary supplements containing biotin, zinc and iron are among the most widely used in cosmetics.

Are there any adverse effects associated with cosmetic dietary supplements?

Yes, in some individuals, dietary supplements used in cosmetics are liable to trigger digestive disturbances and allergic reactions, hence the importance of seeking advice from a healthcare professional before beginning a course.

Are cosmetic dietary supplements considered inadvisable for pregnant women?

This depends on the cosmetic dietary supplements in question. It is always preferable to seek advice from a healthcare professional, a fortiori during pregnancy.

How long does it take for dietary supplements to have an effect on the skin or hair?

Most dietary supplements claim to deliver cosmetic benefits after a three-month course.

Can supplements replace cosmetic treatments?

No, they do not act in the same way as topically applied treatments. Cosmetics target the skin’s surface directly, whereas supplements operate systemically. The two approaches are therefore complementary.

Can dietary supplements improve the appearance of wrinkles?

Certain antioxidant compounds and agents involved in dermal structure have been investigated for their potential roles. The results generally remain modest and require regular intake. They do not replace photoprotection strategies or topical care.

Are dietary supplements regulated?

Yes, they are governed by a specific regulatory framework distinct from that of medicinal products. Their safety and composition must adhere to defined standards.

Is it possible to take multiple dietary supplements simultaneously?

Some combinations may be appropriate, but others can lead to excessive intake. The overall coherence of supplementation should be assessed. Professional guidance is therefore advisable.

Is diet alone sufficient to meet the skin’s requirements?

A balanced diet generally provides the nutrients the skin requires. Supplements may be considered when needs increase or dietary intake is insufficient. They do not replace a varied diet.
