Dear Sir/ Madam
As a personal care product developer It was one of my responsibilities to study on new trends, products and raw materials. I am fully aware of personal care raw materials and their characteristics, which is very useful in preparing marketing content and product informations.
I would be grateful if you could contact me to discuss further details.
Please see the below sample on skincare categories,
How to Determine Your Skin Type
Keep in mind that almost everyone at some time or another has combination skin. That's because the center area of your face naturally has more oil glands, so you are more likely to be oily or have clogged pores in the "T-Zone." Likewise, it is typical for some areas of your face (the eye area, around the nose) to be more sensitive.
Before you get out your mirror and have a close look,
1. Wash your face with a gentle cleanser.
2. Wait for two hours.
3. Dab your face with a tissue. Pay attention to the 'T-zone' the
area of your forehead and nose.
4. Determine your skin type
You may see any combination of the descriptions happening on your face. It bears repeating that anyone's skin can have multiple "types," and that these types can change due to hormonal cycle, season, stress levels, etc.
Best Regards
