FAQ about dietary supplements

Are dietary supplements used in cosmetics safe?

When taken as part of a balanced diet, cosmetic dietary supplements are safe, provided that recommended dosages are respected and a healthcare professional is consulted before starting a regimen.

What are the most commonly used dietary supplements in cosmetics?

Biotin-, zinc- and iron-based dietary supplements are among the most widely used in cosmetics.

Are there any side effects associated with cosmetic dietary supplements?

Yes, in some individuals, dietary supplements used for cosmetic purposes can cause digestive disturbances and allergic reactions, underscoring the importance of consulting a healthcare professional before starting any regimen.

Are cosmetic dietary supplements inadvisable for pregnant women?

This depends on cosmetic dietary supplements. It’s always best to consult a healthcare professional, all the more so during pregnancy.

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

Most dietary supplements claim cosmetic efficacy after a three-month course.

Can dietary supplements replace cosmetic skincare treatments?

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

Can dietary supplements improve the appearance of wrinkles?

Certain antioxidant compounds or molecules involved in dermal structure are being studied for their potential role. The results are generally modest and require regular intake. They do not replace sun-protection strategies or topical care.

Are dietary supplements regulated?

Yes, they are governed by a specific regulatory framework distinct from that of medications. Their safety and composition must meet defined standards.

Can you take multiple dietary supplements simultaneously?

Some combinations may be appropriate, but others can lead to excessive intake. The overall consistency of supplementation should be evaluated. Professional guidance is therefore recommended.

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

A balanced diet ideally supplies the skin with the necessary nutrients. Supplements can be considered when needs are elevated or intake is inadequate. They do not replace a varied diet.
