These ingredients make it possible for your skin to absorb the sunblock components of sunscreen, and they can only be manufactured in a lab. Of course, use common sense about the limits of what sunscreen can do. Even water-resistant sunscreen should be reapplied every two hours for best results. Sitting in the shade, wearing sun-protective clothing and a hat, and limiting your total sun exposure time should be additional parts of your sun-protection plan.
It takes entire teams of chemists years or even decades to tweak and perfect sunscreen products that the FDA finds safe and acceptable.
The chances of you perfecting a safe and effective sunscreen to compare with the products on the market are slim. New natural products are coming out every year, and the FDA has shown concern over possibly harmful ingredients in sunscreens by updating their guidelines. With a proactive, educated consumer base and the strength of the wellness and natural product trends, we can expect better sunscreen options to hit shelves in the summers to come.

But we also take things to a whole other level, because we like to consider the following things too before we start cooking things up in the lab. Before we formulate anything, we ask ourselves about the following things, and the answers will always impact which ingredients we use and why.
Stay tuned for more chemistry lessons — and if you have a question about how sunscreen is made, then just leave it — or your comments — below! Sunscreen products may be manufactured, bottled, and shipped from a single facility, or portions of this work may be handled out-side of the company.
The fully automated manufacturing process described here uses some of both approaches. Sanitized plastic scraps from the container molding process are reground and used again in molding. Containers which have been through the printing process and have flaws are passed on to other companies and made into products such as patio furniture.
Researchers look to nature in search of the next wave in sunscreen development. Some plants have natural defenses against the damaging rays of the sun. For example the single-cell alga called Dunaliella Bardawil that thrives in the Dead Sea and the Sinai desert makes its own sunscreen. Scientists at the Weizmann Institute of Science in Rehovot, Israel, isolated the protein that this plant produces when sunlight gets too intense. The protein acts as a solar deflector by funnelling light down to where photosynthesis takes place.
Excess light which could interfere with photosynthesis is shunned by a yellow-orange pigment produced by the algae. The human body also has a natural defense called melanin. Melanin is the brownish-black pigment found in skin and hair. It reflects and absorbs ultraviolet rays to provide a broad spectrum of protection. Dark-skinned people have a higher concentration of melanin and, as a result, have a lower incidence of skin cancer as well as less physical and medical signs of aging skin.
However it can now be made in an inexpensive procedure using fermentation jars. One technology being used as a method of incorporating melanin into sunscreen lotions is to encapsulate it into microsponges which hold the melanin on the surface of the skin where it is most effective.
The microsponges are invisible to the eye, and can only be seen under a microscope. Researchers continue to gain approval for the many uses of natural and synthetic melanin as an ingredient in sunscreen formulations. Conry, Tom, ed. Consumer's Guide to Cosmetics. Winter, Ruth.
