What the product description says

“The result is a powerful preventative serum that effectively helps reduce the appearance of age spots and hyperpigmentation.”

Source: Regimen Lab US

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: ascorbic acid.

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: epigallocatechin gallate, ferulic acid, resveratrol.

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

Ascorbic acidHeroEffect: HighThe 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~3.7–5.6%

Epigallocatechin gallateKey activeEffect: MediumA polyphenol found in tea. This particular compound abbreviated EGCG is the most powerful antioxidant among those extracted from tea (usually green tea). Unfortunately, EGCG is unstable, requires a low pH (below 4) to prevent quick degradation, and does not penetrate the skin very well. This is why the full anti-oxidant effect of EGCG is typically not realized when it is added to topical skincare~1–1.5%

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%~0.85–1.25%

ResveratrolEffect: LowHelps neutralize free radicals in skin and might help reduce fine lines and wrinkles, as well as even out the skin tone~0.55–1.25%

Anti-aging

Side benefit · Ascorbic acid, Acetyl zingerone + 4 more

Works well

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains ascorbic acid.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: acetyl zingerone, epigallocatechin gallate, ferulic acid, resveratrol.

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.

Acetyl zingeroneKey activeEffect: MediumAn active compound sourced from ginger root. It can help neutralize free radicals in skin. It might be able to help reduce fine lines and wrinkles and improve the skin tone. In small concentrations, used as a chelating agent and helps preserve stability of product formulations.2%

ResveratrolKey activeEffect: MediumHelps neutralize free radicals in skin and might help reduce fine lines and wrinkles, as well as even out the skin tone~0.55–1.25%

TocopherolEffect: LowPure 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~1.2–1.8%

Side benefit · Ascorbic acid, Acetyl zingerone + 8 more

Moisturizing

Side benefit · Glycerin, Propylene glycol + 5 more

Works

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, caprylyl glycol.

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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

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~1.5–2.3%

Propylene glycol· HumectantEffect: LowHelps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritating~2.7–4%

Pentylene glycol· EmollientEffect: LowUsed to preserve products, dissolve other ingredients and create a nice product texture~1.8–2.7%

TocopherolEffect: LowPure 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~1.2–1.8%

Caprylyl glycol· Humectant, EmollientEffect: LowHelps preserve products and creates a nice product texture~0.05–0.25%

LecithinEffect: Low, below effective doseUsed mostly for creating emulsions - helping oil and water mix together. Helps soften the upper layer of the skin~0.15–0.7%
