28 Day Skin treatment serums | Skin repair serum

High-strength vitamin and mineral breakout repair formula​

5% niacinamide, 2% n-Acetyl glucosamine, 1% zinc, amino acid complex serum

How it works

28 Day Skin repair serum is specifically formulated to repair the skin's delicate protective barrier, reduce inflammation and fade acne scaring without the use of irritating ingredients.

We have formulated our serum using a hydrating and cooling aloe vera base and packed our serum with cooperating clinically proven actives at concentrations suitable for sensitive skin:

  • Vitamin B3 (niacinamide), MSM & Zinc PCA to reduce inflammation and decrease enlarged pores while regulating the amount of oil the sebaceous glands produce to help reduce future breakouts.

  • Vitamin B5 (Panthenol) & n-Acetyl glucosamine to help moisturise and hydrate the skin without oils or silicone.

  • Green tea to destroy free radicals, sooth inflammation and help balance the skin's microbiome.

  • Amino acid complex to heal the damage left behind by breakouts.

  • Sodium Hyaluronate to fade the appearance of scars and help build happier skin.

Directions & how to achieve best results

Apply to entire face before moisturising. If irritation occurs, cease use. Use only as directed on unbroken skin.
You should always patch test prior to using a new skincare product. Refer to our in-depth guide to patch testing.

Key ingredients explained: 

Aloe Barbadensis Juice Extract
What it is: Aloe Barbadensis leaf extract, commonly known as Aloe vera.

What it does: the high water content (99.5 per cent) means it's very hydrating, soothing and cooling. It's also an anti-inflammatory. 

Side effects: aloe is generally considered safe.

What it is: niacinamide is an active, water-soluble form of vitamin B3. Despite the similarities in names, niacinamide isn’t the same thing as niacin. 

What it does: anti-inflammatory; effective in repairing the skin’s barrier function; can also help brighten a dull complexion and even out discoloration; reduces enlarged pores; regulates the amount of oil the sebaceous glands produce.

Side effects: topical niacinamide is generally considered safe to use at a 5% concentration. Higher concentrations of 10% or more may cause mild skin reactions such as itching or burning, in some people.

What it is: a provitamin derived from pantothenic acid (Vitamin B5) and alcohol. A provitamin is a substance that is converted into a vitamin inside a living cell.

What it does: acts as a humectant: it draws water from the environment into skin to help maintain skin hydration; can improve signs of aging, such as hyperpigmentation and redness.

Side effects: can cause contact dermatitis in some people. 

N-Acetyl Glucosamine (NAG)
What it is: an amino acid sugar that’s the primary components of Hyaluronic Acid and mucopolysaccharides (these substances have great water-binding properties within the skin).

What it does: a natural moisturiser that keeps skin hydrated; can inhibit melanin production, lighten skin and fade hyperpigmentation spots; effective at healing wounds when used in high concentrations.

Side effects: generally considered to be safe.

Camellia Sinensis (Green Tea) Leaf Extract
What it is: a plant extract derived from the evergreen shrub Camellia Sinesis plant. 

What it does: rich in polyphenols including Epigallocatechin-3-gallate which provides anti-inflammatory properties, destroys free radicals and soothes inflammation. Epigallocatechin-3-gallate is more than two hundred times more effective than vitamin E. Clinically a 2% Green Tea Lotion is an effective treatment for mild to moderate acne with a 58.33% lesion count decrease after 6 weeks after treatment; prevents UVB-induced oxidative stress (the kind that causes wrinkles); prevents collagen breakdown; reduces sebum production.

Side effects: generally considered to be safe.

Dimethyl Sulfone

What it is: MSM (Methyl Sulphonyl Methane or Dimethyl Sulfone) is a natural form of organic sulphur.

What it does: MSM is an anti-inflammatory agent, an antioxidant and enhances the formation of collagen bundles which helps restore the foundation for healthy skin. 

Side effects: generally considered to be safe.

Zinc PCA

What it is: Zinc PCA is the Zinc salt of pyrrolidone carboxylic acid. 

What it does: Zinc PCA has been clinically shown to decrease sebum production.

Side effects: generally considered to be safe.

Sodium Hyaluronate
What it is: a large naturally occurring sugar molecule (polysaccharide) created from a safe bacterial strain called Bacillus subtilis. 

What it does: provides hydration to the skin; hyaluronic acid can hold up to 1000 times its weight in water.

Side effects: generally considered to be safe.

Histidine, Lysine,

What it is: These are essential amino acids.

What it does: Amino acids are the building blocks of peptides and proteins, and each has a specific role in skin care. Amino acids maintain skin’s hydration, texture, resilience, and an overall supple, healthy appearance. Histidine has antioxidant ability and can soothe skin. Lysine helps visibly firm skin’s surface by reinforcing its supportive elements.

Side effects: generally considered to be safe.

Arginine, Carnitine, Carnosine, Glycine, Proline
What it is: These are non-essential amino acids.

What it does: Arginine helps repair visible skin damage from acne scaring. Proline and glycine work with Sodium Hyaluronate in the formula to reduce the look of acne scaring, pock marks, fine lines and wrinkles. Carnitine assists with the breakdown of fats and lipids and has been clinically shown to reduce excess sebum production over 3 weeks of topical use. Carnosine fights oxidative damage to DNA and proteins, such as that caused by UV exposure and has been shown to protect proteins, primarily collagen, from glycation.  It also maintains the barrier function of the skin, both by simple hydration and complex effects in wound healing.

Side effects: generally considered to be safe.

Sclerotium Gum
What it is: Sclerotium Gum is is a polysaccharide produced through a fermentation process (basically fermented sugar)

What it does: Sclerotium Gum reduces the level of oil required in formulas and has natural skin soothing and smoothing properties.

Side effects: generally considered to be safe.

Xanthan Gum
What it is: Xanthan gum is a polysaccharide

What it does: Xanthan gum is used as a stabilizer to prevent products from separating in cosmetics.

Side effects: generally considered to be safe.

Sodium Citrate
What it is: Sodium citrate is the sodium salt of citric acid, a weak organic acid.

What it does: Sodium Citrate is used to control the pH level of a product and has antioxidant and preservative properties.

Side effects: generally considered to be safe.

What it is: Pullulan is a polysaccharide polymer. It is a good water-binding agent, thickening agent, and antioxidant.

What it does: Pullulan provides an instant skin-tightening effect as it adheres to the skin by forming a sheer film that temporarily improves skin's texture and appearance.

Side effects: generally considered to be safe.

What it is: Phenoxyethanol is a widely used synthetic preservative

What it does: Phenoxyethanol works as an antibacterial and/or a preservative in this formulation. It has been indicated to help reduce acne by up to 50% when formulated in combination with other ingredients. 

Side effects: A 100% concentration of phenoxyethanol has been linked to reactions ranging from eczema to severe, life-threatening allergic reactions. This formulation uses a concentration at less than 1%. As with many cosmetic ingredients, concentration matters. The European Economic Community (EEC) Cosmetics Derivative and the Cosmetics Regulation of the European Union approved phenoxyethanol in concentrations up to one percent. The incidence of a sensitised or allergic reaction to phenoxyethanol applied as used in the concentrations found in cosmetics is rare. But the truth is all preservatives, even the natural ones, carry some risk of sensitising skin.
