What the product description says
“Powered by Retin-less technology that safely mimics the properties of retinoids, the skin-brightening treatment helps to reverse signs of ageing and provide protection from sun-induced damage, without the negative effects of Retinol.”
Source: Lookfantastic

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

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~2.6–3.9%
BakuchiolKey activeEffect: HighA plant extract that is, though different in chemical structure, acts similar to retinoids. First studies show that it can help reduce fine lines and wrinkles, improve skin tone, reduce clogged pores and blemishes, and reduce inflammation. There is no conclusive evidence that bakuchiol is as effective as retinol however. The study that directly compared retinol with bakuchiol used bakuchiol applied twice daily compared to once per day for the retinol. According to this study, bakuchiol is less irritating than retinol. Bakuchiol is extracted from seeds of Babchi plant. Other parts of the plant contain coumarins that could cause allergic and irritant reactions. These compounds should be removed in the extraction process when bakuchiol is produced, but it is a good idea to be cautious and stay away from products that include the Babchi plant extracts other than purified bakuchiol to avoid irritation~0.45–1%
Decarboxy carnosine hclEffect: LowMight be able to protect the skin from free radicals, but further evidence of effectiveness is needed~0.2–0.8%

What the product description says
“The light, silky serum targets existing hyperpigmentation and age spots whilst minimising the formation of new ones; its blend of carefully selected active ingredients, including Niacinamide (Vitamin B3), Daisy Flower and Babchi Seed Extract, work in tandem to promote an even, more uniform skin tone.”
Source: Lookfantastic

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: alpha-arbutin, bakuchiol, niacinamide, tranexamic 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.

Alpha-arbutinKey activeEffect: HighMight help reduce hyperpigmentation when used regularly over a long period of time. Is more effective than beta-arbutin~2–3%
Tranexamic acidKey activeEffect: HighAn amino acid that is effective in reducing hyperpigmentation and evening out the skin tone. It can also help in skin barrier recovery. It is used to treat melasma, especially with injections and when taken orally~1.6–2.4%

Moisturizing

Works well

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, saccharide isomerate.

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.

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

Product summary

"Sepai - Flawless Dark Spots Serum" is effective for: Anti-inflammatory, Evens skin tone, Anti-aging, Moisturizing and Anti-blemish

Ingredient callouts

  • A good concentration of Niacinamide (2.60% - 3.90%). 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.
  • Bakuchiol in this product (the concentration is about 0.45% - 1.00%). Helps fight photodamage (wrinkles, elasticity loss and pigmentation) and can reduce clogged pores and blemishes. Bakuchiol is a compound extracted from a plant Babchi. It acts similar to retinoids, but with less irritation risk.
  • Humectants (saccharide isomerate 0.55% - 1.25% and glycerin 3.90% - 5.80%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Price

The product retails for 100.80$ in the United States, from 59.90£ up to 73.00£ in the United Kingdom and for 127.80CA$ in Canada.
