Science: Olay Reviews by NvWah_Olay Definity Night Restorative Sleep Cream

This is good-for-the price moisturizer for slightly mature skin. Though the formulation is very similar to Olay Definity Facial Cream.

The product is richly moisturizing and may not be suitable for oily skin. The ingredient acetyl glucosamine is an amino acid sugar. It is the primary constituent of mucopolysaccharides and hyaluronic acid, both of which have excellent water-binding properties for skin.

Many Olay products contain niacinamide (vitamin B3). Niacinamide (vitamin B3) increase fatty acid contents and prevent skin from dehydration, and improve microcirculation. It may also be a cell-communicating factor. According to Olay’s own research, this ingredient reduces the appearance of wrinkles, skin discolorations, less redness, a reduction in sallowness, and improved elasticity.

The product contains large amount of silicone therefore gives a great deal of slip on the skin. It also helps minimize the look of pores. But the smooth feeling is only temporary and overdose may cause pore-clogging.

There are vitamin C and E, both potent anti-oxidants that eliminate free radical damage and prevent aging. Also the collagen content helps rebuild skin structure and fill in wrinkles.

Safety alert: Cautious

1st ingredient		is water.
2nd ingredient		cyclopentasiloxane is silicone that imparts smooth and velvety feeling to the skin.
3rd ingredient		glycerin transports water from the environment and from the lower layers of skin (dermis) to surface skin (epidermis). It softens the skin. Glycerin is a substance naturally present in skin which helps maintain the epidermis and prevent dryness or scaling.
4th ingredient		niacinamide (vitamin B3) increase fatty acid contents and prevent skin from dehydration, and improve microcirculation. It may also be a cell-communicating factor. According to Olay’s own research, this ingredient reduces the appearance of wrinkles, skin discolorations, less redness, a reduction in sallowness, and improved elasticity.

Skin irritation	Contains hedychium coronarium, a strongly scented ginger that can irritate skin.
Illness		Contains triethanolamine which is used in cosmetics as a pH balancer. Like all amines, it has the potential for creating nitrosamines. Nitrosamines are readily absorbed through skin and they have been proved to be strong carcinogen. Whether or not the concentrations used in cosmetics should be of concern is still a matter of debate.
