Few industry professionals respond with a positive answer, while focusing on the growing number of allnatural and organic products that avoid preservatives. On the other hand, there are multitasking lotions or creams that have a lot of chemical layers, which can raise instability and reduce the life span of the product. Dr. Joel schlessinger is a dermatologist in omaha, and the president and founder of lovelyskin.com. This site specializes in beauty products mostly available in the office of a dermatologist or a cosmetic surgeon. He said that companies end up with excess problems, while creating more complex products to simplify treatments of consumers. People can apply one cream instead of two, as certain products are not compatible with other products.
Dr. Schlessinger stated an example of benzoyl peroxide, which has 3 months shelf life after it is opened and is capable of damaging paired antibiotics despite being sealed. It may work, but eliminate the effect of the other product, if paired with an antibiotic. Vitamin c, antioxidants, plant extracts, glycolic acids and retinol are some common ingredients susceptible to heat and sunlight. Packaging is vital, as well.
A chemist in manhattan, ron robinson, who is a specialist in cosmetic ingredients technology and the founder and chief executive of beauytystat.com that provides reviews for new products, gave an example of an eye cream having high bacterial growth rate due to contents in jars. An internist in austin, texas, followed by being the creator of a product range made a patient&rsquos genetic makeup, called skinshift, dr. Ruthie harper, stated that ingredients with different ph levels may not share the same platform, as one may be too high or consist of more alkaline and the other may be low levelled or have more acidic content.
This blend may result in them becoming inactive or neutral. Moreover, there may not be any chemical compatibility with other ingredients. As a result, more ingredients can reduce the usage. The reduction is mostly unclear. For overthecounter cosmetics or skin care products, except sunscreen, a classified drug, the food and drug administration does not make a compulsion for expiration dates. Expiration dates do not feature on skinshift. However, dr. Harper specified that batch production is monitored and tracked. Stability tests can be performed by companies and products can be stamped in accordance. However, the process is timeconsuming and expensive.
Dr. Schlessinger claimed to have spent 70,000 on stability testing for his product line, fixmyskin balms, which had stamps on each items. He said that many companies dislike delaying their product launch, which could take around six months to a year. Dates are not reliable at all times, despite these measures. Like milk, improper storage or handling can disclaim dates.
The britainbased allnatural company, lush, takes a major selling point to be featuring manufacture and useby dates on every item in its catalog. Lush&rsquos lead product and brand trainer, erica vega, confirmed that the basis of lush, biofresh face masks, can expire post 21 days, invariable of a majority of other goods from lush displaying a shelf life of 14 months. She further said that they are freshly made on a weekly basis with contents of fruits, vegetables, essential oils and cleansing clays before being delivered to shops, where they are placed on ice in the form of a fresh buffet. They desire to offer complete effects of the vitamins, antioxidants and enzymes from the fruits and vegetables used in the making of the product.
Minimum packaging is used by lush, as compared to some companies that sell active ingredients in separate packages. Mr. Robinson explains that when the product is being used, air and bacteria reduce its purity level and efficacy. Product life can be extended with sterile packaging and innovative oneway pumps that do not allow air to enter the package. The month of january seen the release of life radiance double radiance 67 by decléor, wherein the company claims one part cream for radiance and one part gel to protect the skin, put in separate tubes, despite being presented together. Jan marini age intervention duality 90, remède intensive double serum 130, skinmedica tns essential serum 245, and la prairie skin caviar liquid lift 500 are included in such packaged items. The director of research and development for shiseido international france of decléor, michel sabadie, confirmed that as the customer mixes gel and cream before using, no shelf life risk is involved in this case. The shelf life would be less than a day, if they were mixed initially.
At mount sinai medical center in new york, the director of cosmetic and clinical research in the dermatology department, dr. Joshua zeichner, stated that scientific validity is available for separating active ingredients until the time of application. Companies can logically create new ways to distribute combination therapies and ingredients that have the potential to deactivate each other. Mr. Robinson claimed it to be clever marketing with a visual cue, as two products are offer in one consumer takeaway with two benefits. He further said that whether products have expiration dates or not, storing them in a cool place is better than storing in the bathroom, where it is hot, humid and wet, most of the time. This can extend the shelf life of the product. Bacteria can be decreased by the use of an applicator or cotton swab and not a finger. Water invites germs, so avoid adding it. People ought to know when to let go of a product like any relationship. Mr. Robinson stated that when a product separates, changes color or smells, it has to be discarded.
