The cornflower hydrosol does not require any specific usage precautions. For instance, it can be applied around the eye area or on the entire face without any risk of irritation. As for the use of cornflower hydrosol in pregnant or breastfeeding women and young children, there are also no contraindications.
However, 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. Make sure 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 means it is not well tolerated by the skin and it is better to avoid using it. If no reaction is observed, this means that the skin tolerates it well.
Furthermore, in order to minimize potential risks, it is crucial to be vigilant about the preservation of cornflower hydrosol. Primarily composed of water, hydrosols are indeed quite susceptible to bacterial contamination, which can cause adverse effects on the skin. To prevent the growth 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's also worth noting that it's advisable to use the cornflower hydrosol within six months of opening. However, if it shows a change in color or smell earlier, it is better to stop using it and discard it.
Recommendation : Before each use, it is advised to always check the condition of the cornflower hydrosol by analyzing its organoleptic characteristics, such as its smell, color, appearance, and texture.
