Science: Garnier Nutritioniste Ultra-Lift Pro Deep Wrinkle Roller Reviewed by NvWah

First of all I think roller is a clever idea. There are many good ingredients in this product which I will elaborate later for a modest price. But, there is a huge turn-off too.

The fourth abundant ingredient, propylene glycol (PG), is derived from petroleum and used in cosmetics as solvents, surfactants, and wetting agents. It is used to enhance ingredient penetration and as a humidifying agent. It is easily absorbed through skin and is a potent skin irritant. PG could easily provoke skin irritation and sensitization at concentration as low as 2%. In fact U.S. Environmental Protection Agency (EPA) has issued a warning to avoid skin contact to prevent brain, liver, and kidney abnormalities. To be listed as the fourth abundant ingredient just worries me about how much of this harmful ingredient I would absorb from daily use.

Also be cautious that another main ingredient PEG-60 hydrogenated castor oil is not safe for use on injured or damaged skin.

There are indeed many noteworthy ingredients in it. For example rosa canina oil is rose hip oil which is richly moisturizing and could enhance the natural rebuild of skin cell.

This product does indeed may have some wrinkle rescue and anti-aging properties. Two ingredients, saccharum officinarum (Sugar cane) extract and sugar maple (Acer saccharum) extract are both rich in AHA, which provides moisturizing and anti-aging effect. AHAs is alpha hydroxy acid. AHAs exfoliate the surface skin by breaking up cell-connecting materials. As a result fresh and smoother skin is revealed. AHAs, including glycolic and lactic acid, are widely used to treat aged skin by normalizing thickened skin and increasing skin water content. But the exfoliating properties may also irritate skin. Overdose of AHAs may make users more sensitive to UV radiation. Always wear sunscreen when using AHA products.

In the same category soy protein actively protects against free radicals. So it's a potent anti-oxidant and anti-inflammatory agent. It also stimulates collagent production and affects skin thickness and elasticity. Another ingredient, ginger root extract has long been used in Asian herbal therapy and is believed to have youth-renewing effect. It has anti-inflammatory and anti-carcinogenic activity when eaten. It is believed to act as antioxidant topically.

The claimed ingredient hydroxypropyl tetrahydropyrantriol (trade mark "Pro-Xylane") is shown to stimulate GAG synthesis, restoring water and nutrients to the dermal epidermal junction. GAG is short for glycosaminoglycans which are any of a group of compounds occurring chiefly as components of connective tissue. But according to enviromental working group (EWG), Pro-Xylane has not been assessed for safety in cosmetics by industry panel.

It would be better without the alcohol and fragrance content.

Overall I have mixed feelings for this product. But due to the too-much propylene glycol amount, I personally would stay away from it.

Safety alert: Elevated
review based on scientific information of the product ingredients.

1st ingredient		is water.
2nd 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.
3rd ingredient		dimethicone is silicone that imparts instant but temporary smooth feeling to skin.
4th ingredient		propylene glycol is derived from petroleum and used in cosmetics as solvents, surfactants, and wetting agents. It is used to enhance ingredient penetration and as a humidifying agent. It is easily absorbed through skin and is a potent skin irritant. PG could provoke skin irritation and sensitization at concentration as low as 2%. In fact U.S. Environmental Protection Agency (EPA) has issued a warning to avoid skin contact to prevent brain, liver, and kidney abnormalities.

But this is a harsh chemical that can cause skin irritation even at miniscule amount. contains citrus aurantium dulcis (Orange) fruit extract which is bitter orange extract. It has antioxidant properties when eaten but topical use is potentially irritating to skin due to its methanol content.
