The cornflower hydrosol does not require any specific usage precautions. For instance, it can be applied around the eye area or over the entire face, without any risk of irritation. Regarding the use of cornflower hydrosol in pregnant or breastfeeding women and young children, there are also no contraindications.
Nevertheless, as with any cosmetic product or ingredient, it is recommended to perform a skin test before the first use. To do this, simply apply a small amount of cornflower hydrosol to the crook of your elbow, behind the ear, or on the inner side of your wrist. Ensure to spread the product well and allow it to properly penetrate the skin. After 24 to 48 hours, you can observe if the product has caused a skin reaction at the site of application. If the cornflower hydrosol has caused tingling or redness, this indicates that it is not well tolerated by the skin and it is advisable to avoid using it. If no reaction is observed, this means that the skin tolerates it well.
Furthermore, in order to minimise potential risks as much as possible, one must be vigilant about the preservation of cornflower hydrosol. Essentially composed of water, hydrosols are indeed quite sensitive to bacterial contamination, which can cause adverse effects on the skin. To prevent the proliferation of pathogens, it is recommended to store the cornflower hydrosol in a completely airtight container and keep it away from moisture, heat and light. It should also be noted that it is advisable to use the cornflower hydrosol within six months of opening. However, if it shows a change in colour or smell earlier, it is better to stop using it and discard it.
Recommendation : Prior to each use, it is advised to always check the condition of the cornflower hydrosol by analysing its organoleptic characteristics, such as its smell, colour, appearance, and texture.
