What the product description says
“A 5% vitamin C And niacinamide serum that visibly brightens skin, reduces the appearance of hyperpigmentation, and boosts overall glow.”
Source: Follain

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

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: 3-o-ethyl ascorbic acid.

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.

3-o-ethyl ascorbic acidKey activeEffect: MediumA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help 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~2.7–4%
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~2–3%
Anti-aging

What the product description says
“Niacinamide Helps reduce the appearance of pores, fine lines, and wrinkles”
Source: Credo Beauty

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

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.

Exfoliation
No ingredient credited for this claim
Not delivered
What the product description says
“Fruit-derived AHA Gently exfoliates skin, helps resurface texture, and helps refine pores”
Source: Credo Beauty

This product does not contain effective exfoliating ingredients. It might be able to deliver physical exfoliation, that is scrub off some of the dead cells on the surface of the skin. We do not recommend physical exfoliation, because it is not uniform (some bits of skin can get exfoliated too much while others not at all). It can also traumatize the skin and aggrevate acne and other skin conditions.

Anti-blemish
Side benefit · Niacinamide, Inulin
Works well

This product can help reduce breakouts and clogged pores because it contains the following ingredient: niacinamide. This ingredient is used for treating acne and can have a noticeable effect.

InulinEffect: LowHelps attract water to the upper layer of the skin. Is claimed to support the growth of "good" bacteria in skin (as a "prebiotic"), but the research is lacking~0.2–0.8%
Moisturizing
Side benefit · Niacinamide, Glycerin + 7 more
Works well

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

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).

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

May help

This product contains antioxidants (3-o-ethyl ascorbic acid) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.

Product summary

"Follain - BRIGHTENING SERUM: Vitamin C Boost" is effective for: Anti-blemish, Anti-aging, Evens skin tone and Moisturizing

Ingredient callouts

  • A good concentration of Niacinamide (2.00% - 3.00%). Niacinamide is a well-studied multi-tasking active. 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 improve the skin tone, reducing pigmentation marks.
  • Humectants (glycerin 0.20% - 0.80% and sodium hyaluronate 0.05% - 0.15%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
