Kiehl’s Powerful Strength Line Reducing, Analysis And Alternative

Kiehl’s Vitamin C Serum contains 12.5% ​​vitamin C, in the form of L-ascorbic acid and ascorbyl glucoside. It also has the presence of hyaluronic acid, a good vitamin supplement.

The brand has improved the formula to create a cosmetic capable of visibly reducing fine lines, brightening the skin and improving its texture.

According to the brand, its safety has been tested by dermatologists, so we hope not to find any potentially dangerous ingredient for our health.

To check this, we will analyze your INCI. When you finish reading the analysis, I recommend that you take a look at this other article with the Best Serums with Vitamin C that you can find right now on the market.

Kiehl’s Powerful Strength Line Reducing Analysis

  • Propylene Glycol : Analyzed in the eye contour Revitalift Laser X3 of L’Oreal .
  • Dimethicone : Tested in Shiseido Men’s Anti-Wrinkle Cream for Men .
  • Glycerin : Tested in Clarins Men’s Anti-Wrinkle Cream .
  • Ascorbic Acid (10.5%) : Analyzed in the Lancaster Skin Therapy eye contour .
  • Ethylhexyl Palmitate : Analyzed in Filorga’s Ultralifting Lift Designer serum .
  • Cetyl Peg / Ppg-10/1 Dimethicone : A silicone, also known as cetyl dimethicone copolyol or by its trade name Ambil EM 90. It is a skin and hair conditioning agent, emulsifier and delivery agent. As a silicone, it provides emolliency, water binding properties, good glide and a silky feel on the skin. It maintains the separation of the water and oil parts of an emulsion and has a great trapping capacity that allows it to prolong the release of active molecules, especially pigmented ones. It also conditions the skin, gives it a smooth and smooth appearance and removes any adhesion. It is considered safe for use in cosmetic products, although PEGs are believed by many to act as toxic carcinogens.
  • Dimethicone Crosspolymer : Same as the Dimethicone ingredient, discussed above.
  • Ascorbyl Glucoside (2%) : Analyzed in the anti-wrinkle cream Vita Lift 5 from L’Oreal Men Expert .
  • Cyclohexasiloxane : Analyzed in the anti-wrinkle cream Vita Lift 5 from L’Oreal Men Expert .
  • Hydroxyethylpiperazine Ethane Sulfonic Acid : Analyzed in the Revitalift Laser X3 eye contour from L’Oreal .
  • Lauroyl Lysine : An amino acid derivative that is made from natural coconut fatty acids (coconut oil). It is most often used as a hair and skin conditioning agent, although it is also used in product formulation as it contributes to the texture of the product by assisting in the formation of gel solvents. Some studies have shown that the component may also be useful in the treatment (but not cure) of colds, as it inhibits the reproduction of the herpes virus.
  • Acrylonitrile / Methyl Methacrylate / Vinylidene Chloride Copolymer : A type of microsphere plastic that becomes moldable at higher temperatures and solidifies on cooling, generally used as a filler. If filled with gas (such as isobutane), it improves the skin feel of aqueous gel formulas and makes them very comfortable and smooth.
  • Polysilicone-11 : Analyzed in the Lancaster Skin Therapy eye contour .
  • Adenosine : Analyzed in the eye contour Génifique Yeux Light Pearl De Lancome .
  • Hydrolyzed Hyaluronic Acid : Analyzed in the Revitalift Laser X3 eye contour from L’Oreal .
  • Limonene : Tested in Clarins Men’s Anti-Wrinkle Cream .
  • IsobutaneAlso called methylpropane, isobutane is a colorless, odorless gas derived from petroleum and natural gas. It is used as a substitute for CFCs in cosmetic products such as hair sprays. It is also a foaming agent, which is why you will find it in mousses and shaving creams. It also has solvent properties, which means it can also show up in your cleaning products, hair conditioners, and makeup. In this case, it will most likely be used as a filler for the Acrylonitrile / Methyl Methacrylate / Vinylidene Chloride Copolymer microspheres mentioned above. Isobutene is listed as a moderate hazard, primarily because it can cause allergic reactions. However, because it is a gas, the evidence is limited for its effects on the skin. Up to now,any evidence of adverse effects on the skin is limited to the liquid form, which is only available at very cold temperatures and can cause frostbite. Inhalation can cause coughing, wheezing, and shortness of breath. So far, there is no evidence that isobutene causes cell damage or promotes cancer.
  • Citrus Aurantium Dulcis (Orange) Peel Oil : Analyzed in Vichy’s Liftactiv anti-wrinkle cream for men .
  • Citrus Limon Peel Oil / Lemon Peel Oil : Analyzed in Vichy’s Liftactiv anti-wrinkle cream for men .
  • Citral : Tested in Clarins Men’s Anti-Wrinkle Cream .
  • Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate : Analyzed in Kiehl’s Facial Fuel anti-wrinkle cream for men .

Kiehl’s Powerful Strength Line Reducing Analysis Summary

Vitamin C (the star of the serum) is in fourth and eighth places in its two types (L-ascorbic acid and ascorbyl glucoside), which means that it is in a good concentration (in fact, the brand already indicates us the proportions).

What is not in such a good proportion is hyaluronic acid, which is at the bottom of the list. This means that the benefits of serums that have to do with the visible reduction of expression lines, are surely the work of silicones.

For my taste, it has too many silicones, and they are in a high proportion, which gives a fuller, firmer look to the skin, but this sensation is only temporary, it does not last long.

Rightly, the serum does not contain any irritating, sensitizing, or toxic ingredients. I have only found one ingredient that can generate free radicals in the presence of oxygen, something that would not be beneficial for our skin, since we seek precisely the opposite, to eliminate them.

Alternative

If you prefer a serum without silicones, irritants and that does not contain any ingredient that can produce free radicals, try Nezeni Cosmetics vitamin C serum.

Its assets are in a higher concentration, and its effectiveness will be more actively noticed than that of Kiehl’s. In addition, it has the advantage that its level of preservatives is very low, which helps to avoid the combined effect of cosmetics.
