Ovum

1. Definition Ovum:

Ovum in cosmetics refers to the use of egg extract or egg-based ingredients in beauty products. Ovum is rich in proteins, vitamins, and minerals that can benefit the skin and hair.

2. Use:

Ovum is commonly used in skincare products for its nourishing and moisturizing properties. It can help to improve skin elasticity, reduce the appearance of fine lines and wrinkles, and promote a smoother, more radiant complexion. In hair care products, ovum can help to strengthen and condition the hair, leaving it looking healthier and more lustrous.

3. Usage Ovum:

When using ovum-based cosmetics, it is important to be aware of any potential allergies to egg proteins. Individuals with egg allergies should avoid using products containing ovum to prevent any adverse reactions. It is also recommended to perform a patch test before using ovum-based cosmetics to check for any sensitivity or irritation.
