After 1 week, a 16% reduction in oiliness (Statistically significant change from baseline (p≤0.05). Protocol: A 12-week, single-center clinical studies conducted on 60 men and women ages 18-50 with oily and blemish-prone skin. Silymarin CF was applied once daily in conjunction with a sunscreen. (Brazil, 2020)).

At 4-weeks 12% improvement in overall appearance, 13% improvement in clarity, and 13% improvement in Post-Inflammatory Hyperpigmentation. After 8 weeks, a 25% improvement in clarity, 38% improvement in texture, 24% improvement in fine lines, 38% improvement in radiance, 28% improvement in skin tone evenness, 41% improvement in overall appearance (Statistically significant change from baseline (p≤0.05).

How To Use

Gently press 4-5 drops of the vitamin c serum onto skin after cleanser and toner, focusing on the facial canvas, neck and chest before completing your skincare routine for oily skin.

Ingredients

  • L-Ascorbic Acid L-ascorbic acid is a potent form of Vitamin C that provides skin with effective protection against free radical damage, in addition to minimising the signs of visible ageing. This l-ascorbic acid serum contains 15% of the powerful antioxidant ingredient to refine skin texture, enhance skin radiance and reduce oxidative damage.
  • Silymarin Silymarin is an antioxidant derivative of milk thistle, ideal for oily and acne-prone skin types as it works to prevent oil oxidation and is non-comedogenic so prevents the formation of clogged pores. The Silymarin CF Antioxidant Serum contains 0.5% silymarin, boosting antioxidant benefits for protection against free radicals.
  • Ferulic Acid Ferulic acid enhances the effects of other antioxidants such as Vitamin C, to neutralise free radicals and provide preventative protection against visible signs of ageing such as fine lines, wrinkles and dark spots. This antioxidant serum is formulated with 0.5% ferulic acid to protect skin from external aggressors such as UV radiation.
  • Salicylic Acid Salicylic acid is a BHA that offers skin a chemical exfoliation to refine pores and prevent the formation of blemishes, making the ideal ingredient for oily and acne-prone skin. The Silymarin CF vitamin c serum is formulated with 0.5% salicylic acid for effective oil-control and decongestion.

Science & Proof

Growing research shows a link between oil oxidation and the formation of blemishes. When skin’s oils oxidize, this specific type of free radical damage can cause a cycle of inflammation and bacteria that is linked to blemish formation. Daily environmental aggressors like sun and pollution can generate free radicals that further oxidize skin oils. Silymarin CF is scientifically demonstrated to reduce oil oxidation by up to 76%. This combination antioxidant serum is formulated under the Duke Antioxidant patent.

Vitamin C is a highly-potent antioxidant that by its structure has difficultly being effectively absorbed by skin. The Duke Antioxidant patent outlines the formulation parameters required for effective delivery of vitamin C to skin: 1) pure l-ascorbic acid (vitamin C); 2) an acidic pH within the 2.0-3.5 pH range and; 3) a concentration between 10%-20%. SkinCeuticals is the only brand to formulate antioxidants according to these parameters.

Intensive exposure - 68% protection from Erythema at 3x MED (One exposure of x3 minimum erythema doses represents a more intensive exposure one would receive on a sunny day at the beach). Daily exposure - 79% protection from erythema at 1x MED (three consecutive daily exposures of one mimum erythema dose represents chronic inflammation from UV exposure one would encounter in daily life) (Protocol: 10 subjects received application of Silymarin CF on the back for four consecutive days followed by UV-irradiation with one exposure of 3x MED or three consecutive daily exposures of 1x MED. Measurements of erythema and photography were taken 24 hours after the final exposure.)

X-Large is about a size 12-13 shoe size foot USA.
Material Type: Black - 3 Pairs, Size: X-Large
I love them they work fantastic. I am a big guy with swollen feet. Wear size 12 to 13 USA Shoes. They fit me just fine not tight. My feet felt good after wearing them for two days. Some dry skin pulled off with them and it says to wash by hand. I dont know about the durability but I am hoping to get about 5 uses per pair. Before they become unusable.

Comfortable
Material Type: Black - 2 Pairs, Size: X-Large, Material Type: Black - 2 Pairs, Size: X-Large
I have very sensitive skin, so I usually need to wear socks at all times. These are especially comfortable because they don’t cover the toes, which helps with temperature control. The material is well-balanced—not too thick or too thin—and has just the right amount of stretch. I also appreciate the large traction area, which adds stability. Another plus is that they are completely fragrance-free.

Great Heel Socks
Material Type: Black - 3 Pairs, Size: Large
I don't know how they work but it's wonderful. I've had rough heel problems for a long time. I wear these everyday and my heels are not rough. They're not baby bottom smooth, but they are not ever going to be. These heel socks also oncce they are properly positioned snap onto the heel. Properly positioning them is easy when you put them on your foot with the heel cup in the correct orientation.

Too small
Material Type: Gray - 3 Pairs, Size: X-Large
Too tight! Even size large used for a man with smaller feet is too tight. Also, no instructions for use or care.

Good fit
Material Type: Black - 3 Pairs, Size: X-Large
My husband just started using these and they feel comfortable. Hasn't used them long enough to see if his heels are better. He has a high arch so I bought him the XL and they fit perfectly.
