Anti-aging
What does the product description say?
Meet the clock-stopping serum that future-proofs your skin to help combat early signs of ageing.
Source: 111skin
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: centella asiatica extract.
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.
Is 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
A 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.
A stable derivative of vitamin C. It is oil-soluble which means it is more likely to penetrate the skin compared to the pure form of vitamin C (which is water-soluble), but it is less bio-available and is way less effective in stimulating collagen and reducing wrinkles compared to the pure form of vitamin C (L-ascorbic acid) and its other derivatives (for example, magnesium ascorbyl phosphate). At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin C

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.

Moisturizing
What does the product description say?
Upon application, the cooling, velvety texture absorbs effortlessly into skin, leaving it feeling immediately nourished, softer, and more hydrated.
Source: 111skin
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, caprylyl glycol.
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: beta-sitosterol, glycosphingolipids.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide
