That is so wonderful of you to ask only serious suggestions.If you wisely use make up, it will become plus point to your personality. Now that you are growing up and very young, your skin is still going through many hormonal changes.
At such youthful age you should prefer less make up and cosmetics. Here I'm giving you basics of beautiful skin and make up which will make you look naturally beautiful.
You have beautiful brown eyes so for natural look use earthy hues like light and dark brown, chocolate, honey and dark shades. These colors will give natural look to your eyes. You can use peach and subtle shades of pink and red.
Always remember basic rule for choosing foundation is one shade darker than your skin tone. Use nice quality compact powder for fresh and natural skin. The basic need for good make up is moisturizer.
Here are simple steps to great make up. Clean your skin with good mild face wash. Apply light moisturizer with sunscreen. These days every product come with sun protection factor. Then apply mineral or liquid foundation, which ever suits your skin. Blend it carefully in skin with help of brush or finger tips. Later apply nice compact on skin. You can use light colors like peach, pink for blusher. Usually you don't need blusher in daytime. Use a good lip balm or liquid lip color of peach to pink spectrum.
For evening you can use bright and vibrant colors like red, orange and crimson. Apply mascara on eye lashes. This will have most natural effect. You can use mascara for day look. Bronze will look great for evening. Now very important tip, never use brown and shades of brown for lips. These colors on lips make you look mature. If you are afraid of hot weather then use some ice on your skin before applying moisturizer. This will help to maintain make up on skin for longer time.
Last thing for flawless skin and make up is to have good cleanser and make up remover. If you will not remove your make up, it will damage your skin. Always keep lip balm, moisturizer and compact with you. Hope this will give you natural look.
