Environmental engineering science is the study of the principles and concepts of environmental engineering, including the scientific understanding of environmental systems and processes. It focuses on the theoretical and scientific aspects of environmental issues, such as air and water quality, pollution control, and waste management. On the other hand, environmental engineering involves the application of engineering principles to solve environmental problems and design solutions for sustainable development. It includes the practical implementation of technologies and strategies to address environmental challenges, such as designing and constructing water treatment systems, developing renewable energy sources, and implementing pollution control measures. In summary, environmental engineering science is the theoretical foundation, while environmental engineering is the practical application of that knowledge. **

Both Vitamin C serum and serum with Niacinamide offer unique benefits for the skin. Vitamin C is known for its antioxidant properties, helping to brighten the skin, reduce hyperpigmentation, and protect against environmental damage. On the other hand, Niacinamide is great for improving the skin's texture, reducing redness, and minimizing the appearance of pores. The choice between the two would depend on your specific skin concerns and goals. It may be beneficial to incorporate both into your skincare routine for a well-rounded approach to skin health. **

Serum is produced by collecting blood from a donor and allowing it to clot. The clot is then removed by centrifugation, leaving behind the liquid portion of the blood, which is the serum. This serum contains various proteins, hormones, electrolytes, and other substances that can be used for diagnostic testing or research purposes. Serum can be stored at low temperatures to preserve its stability and integrity for future use. **

Using serum instead of primer can be a great alternative for those looking for a more lightweight and hydrating option. Serums are packed with active ingredients that can help improve the overall health and appearance of the skin, while also providing a smooth base for makeup application. However, it's important to note that serums may not provide the same level of pore-filling or mattifying properties as a traditional primer, so it's best to choose a serum that specifically targets your skin concerns and makeup needs. **

The permissibility of using eyelash serum in Islam depends on the ingredients used in the product. If the serum contains any haram (forbidden) ingredients, such as alcohol or animal-derived substances not slaughtered according to Islamic guidelines, then it would be considered haram to use. However, if the serum is made from halal (permissible) ingredients, then it would be permissible to use. It is important for individuals to carefully check the ingredients of the eyelash serum and consult with a knowledgeable religious authority if they have any doubts about its permissibility. **

Eyelash serums can potentially be dangerous if they contain harmful ingredients or if they are not used according to the instructions. Some serums may contain prostaglandin analogs, which can cause eye irritation, discoloration of the eyelids, and even change the color of the iris. It is important to carefully read the ingredients and instructions of any eyelash serum before using it, and to consult with a healthcare professional if there are any concerns about its safety. **

Yes, environmental education should be introduced as a new subject in schools.
