What the product description says
“Surrender to soft, smooth skin with this powerful yet gentle 3-in-1 resurfacing sérum comprised of 8% vegan lactic acid, a trifecta of bioactive flower acids and polyhydroxy acid to exfoliate, brighten, stimulate cell renewal and dramatically retexturize overnight.”
Source: Bluemercury

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: lactic acid.

Lactic acidKey activeEffect: HighAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~4.6–6.9%
GluconolactoneUnder-dosedA polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals~0.1–0.5%

What the product description says
“This transformative, maritime-rich formula is brimming with proprietary algae, microalgae and aqueous herbs that visibly tighten, strengthen the hydrolipidic barrier and retain moisture.”
Source: Bluemercury

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, lactic acid.

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, chondrus crispus extract.

Evens skin tone
Not advertised by the brand · Lactic acid, Gluconolactone
Works well

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

Product summary

"MARA - Flower Acid Algae Serum" is effective for: Exfoliation and Evens skin tone

This product could be helpful for: Anti-aging and Moisturizing, but its actives are not the most effective or are not well-studied.

Ingredient callouts

  • Exfoliating acids (lactic acid 4.60% - 6.90%). In this concentration, they will have a noticeable exfoliating effect. They can also have an anti-aging effect and stimulate collagen production in a long-run. PHAs (gluconolactone 0.10% - 0.50%) in this product also work for improving skin hydration. They might be even able to stimulate the production of skin's natural humectants and support the healthy skin microbiome.
  • Humectants (glycerin 0.55% - 1.30% and lactic acid 4.60% - 6.90%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
