Moisturizer or moisturiser is a cosmetic preparation used for protecting, moisturizing, and lubricating the skin. These functions are normally performed by sebum produced by healthy skin. The word "emollient" is derived from the Latin verb mollire, to soften.
Water constantly evaporates from the deeper layers of the skin, an effect known as transepidermal water loss (TEWL). By regulating its water content, skin maintains a dry, easily shed surface as a barrier against pathogens, dirt, or damage, while protecting itself from drying out and becoming brittle and rigid. The ability to retain moisture depends on the lipid bilayer between the corneocytes.
Emollients prevent evaporation of water from the skin by forming an occlusive coating on the surface of the stratum corneum. TEWL is normally about 4–8 g/(m²⋅h). A layer of petrolatum applied to normal skin can reduce the TEWL by 50–75% for several hours. Humectants also have an emollient effect, but they act differently, by drawing water into the stratum corneum. The more lipid in the formulation, the greater the emollient effect.
Ointments are more emollient than oily creams which are more so than aqueous creams, while most lotions have no emollient effect. Kinds Emollients are available as lotions, creams, ointments, bath oils, or soap substitutes. Petrolatum (White Soft Paraffin) is probably the most effective emollient.[citation needed] Other popular emollients are castor oil, cetyl alcohol, cetearyl alcohol, cocoa butter, isopropyl myristate, isopropyl palmitate, lanolin, liquid paraffin, polyethylene glycols, shea butter, silicone oils, stearic acid, and stearyl alcohol.
Mineral oils and waxes are insensitive to oxidation or rancidity. For this reason, they have essentially replaced vegetable oils in emollients and topical medication. Emollient cosmetics may additionally contain antioxidants, ceramides, emulsifiers, fragrances, humectants, penetration enhancers, preservatives, and solvents. Some products are marketed as having anti-wrinkle and skin enhancement effects. Many plant and animal extracts have been claimed to impart skin benefits, with little scientific evidence.

While there isn't a law requiring ecommerce stores to have a Return Policy, you may need one if you wish to enforce your terms and parameters of returns and refunds.
For example, in the state of New York, if a retailer does not provide a Return & Refund Policy, the retailer will be required to accept returns and give refunds for all merchandise returned within 30 days of purchase. If you wish to limit this in any way, you will need to create and post a Return Policy with your own custom terms.
Another reason for having a Return Policy even if not required by law is that most consumers prefer to shop at retailers with a clearly-posted Return Policy. This is especially important when shopping online, as more issues are likely when purchasing something without being able to see it in person first.
If you don't have a Return Policy, you may be at the mercy of state laws regulating return and refund time frames. You may also lose potential customers who are concerned about not being able to return a product if they need or want to.
