What the product description says
“DESCRIPTION KSecret Vita Collagen Secret Whitening Bar 110g Contains 12 kinds of Vitamin complex and Niacinamide to help boost the radiance of your skin.”
Source: Lila Beauty

This product contains folic acid. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

Folic acidKey activeEffect: MediumCan help stimulate collagen production in skin. While available studies are promising, more research is needed to confirm the efficacy in skin~0.2–0.7%
TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.2–0.75%
Ascorbic acidUnder-dosedThe most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging~0.45–1.05%
Centella asiatica extractUnder-dosedA plant extract that has been shown to be able to reduce inflammation in skin, support restoration of skin barrier function, as well as support collagen production. Contains active compounds called centelloids: asiaticoside, madecasosside, asiatic acid and madecassic acid. Might be helpful in preventing stretch marks. It can be itself be irritating though.~0.35–0.85%
NiacinamideUnder-dosedIs 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~0.15–0.55%
Retinyl palmitateUnder-dosedThree steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect~0.15–0.55%

What the product description says
“Deeply hydrates, soothes and improves the skin barrier of your skin.”
Source: Lila Beauty

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, hydrolyzed collagen.

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: helianthus annuus seed oil, hydrolyzed collagen.

GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~22–34%
SucroseKey active· HumectantEffect: HighCan help attract water to the upper layer of the skin. In crystal form, it can work as a gentle exfoliant, gentler than the salt scrub. Helps stabilize the emulsion~0.6–1.4%
Olea europaea fruit oilKey active· EmollientEffect: MediumAn emollient that helps soften the skin but is not effective for restoring its barrier function. Might be helpful to calm down inflammation~0.35–0.85%
Hydrolyzed collagenKey active· Humectant, EmollientEffect: HighA typically plant-derived compound that is supposed mimic human collagen. Cannot penetrate the skin barrier so is not particularly useful in skincare products beyond attracting water to the upper layer of the skin~0.3–0.7%
Helianthus annuus seed oilKey active· Emollient, OcclusiveEffect: HighA great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function~0.2–0.8%
CyanocobalaminKey activeEffect: HighCan support skin barrier function and reduce inflammation in skin~0.15–0.7%
Pantothenic acidKey activeEffect: HighHelps attract water to the upper layer of the skin and may help reduce inflammation in skin~0.15–0.6%
Propylene glycol· HumectantEffect: LowHelps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritating~4–6%
Sorbitol· HumectantEffect: LowHelps attract water to the upper layer of the skin and improves the product texture~0.5–1.15%
BiotinEffect: LowMight have some moisturising properties. Is not effective when applied topically beyond some moisturizing effect~0.1–0.5%

TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.2–0.75%
Simmondsia chinensis seed oilUnder-dosedSoftens the upper layer of skin and helps restore the healthy skin barrier. Has shown to help calm down inflammation in skin. It is a stable oil, meaning that it retains its properties even when exposed to air.~0.4–0.9%

Product summary

"K-SECRET - Buy Vita Collagen Secret Whitening Bar in Australia - Korean Skincare Online" could be helpful for: Anti-aging and Moisturizing, but its actives are not the most effective or are not well-studied.

Ingredient callouts

  • This product also contains Vitamin C (Ascorbic Acid). It can be an effective active for anti-aging and evening out the skin tone, but in this product it is used for stabilizing other ingredients in the formulation. In this concentration (0.45% - 1.05%) it cannot have a noticeable benefit for the skin.
  • This product includes a form of Retinoids (vitamin A) - retinyl palmitate 0.15% - 0.55%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.
  • Humectants (hydrolyzed collagen 0.30% - 0.70%, sucrose 0.60% - 1.40% and glycerin 22.00% - 34.00%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Price

The product retails for 16.95A$ in Australia.
