“Formulated with the unique SYNBRIGHT® complex to visibly correct dark spots and stabilised vitamin C brighten the skin and protect from free radical damage and premature signs of ageing.”
Source: N/A

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains acetyl glucosamine, niacinamide.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: ascorbyl glucoside, ferulic acid.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

Ascorbyl glucosideKey activeEffect: MediumA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Has a potential to boost collagen production, nutralise free radicals and reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~5.7–8.6%
NiacinamideKey activeEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~3.7–5.5%
Acetyl glucosamineKey activeEffect: HighAn effective moisturizing ingredient that also has been shown to be effective in evening out the skin tone and reducing hyperpigmentation. It can help somewhat reduce wrinkles in skin~1.3–1.9%
Ferulic acidKey activeEffect: MediumA potent anti-oxidant that has been shown to be effective in neutralizing free radicals in skin. There seem to have a synergetic effect of ferulic acid, vitamin E and C, meaning that when the ingredients are used together, they enhance each other's ability protect the skin against free radicals. Ferulic acid also helps to stabilize other ingredients - including vitamins C and E. It can help to even out the skin tone. Ferulic acid is approved for use as a sunscreen ingredient in Japan in concentrations up to 10%~0.5–1.15%

What the product description says
“Niacinamide for skin hydration”
Source: Swisse

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: glycerin, bis-peg-18 methyl ether dimethyl silane.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: caprylic/capric triglyceride, helianthus annuus seed oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl glucosamine, niacinamide

NiacinamideHeroEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles.

Product summary

Judging from the ingredient list, "Swisse Skincare - Vitamin C 5% Niacinamide 5% Brightening Day Cream" works well for improving skin hydration The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Humectants in this product (acetyl glucosamine, glycerin and bis-peg-18 methyl ether dimethyl silane) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Caprylic/capric triglyceride, helianthus annuus seed oil, coco-caprylate, bis-peg-18 methyl ether dimethyl silane and c13-14 isoparaffin in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

Ingredient callouts

  • We particularly like that there is a good concentration of Niacinamide (3.70% - 5.50%) in this moisturizer. Niacinamide is a well-studied multi-tasking active. It is a great ingredient to have in a moisturizer. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and help improve the skin tone, reducing pigmentation marks.

Irritation risk
