Product Summary

Ingredient callouts
- this product includes a form of Retinoids (vitamin A) - retinyl palmitate 0.10% - 0.35%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.
- Humectants (hyaluronic acid 1.30% - 1.90% 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 774.90A$ in Australia, for 603.53$ in the United States and from 249.99£ up to 390.00£ in the United Kingdom.

Anti-oxidation
This product contains antioxidants (arbutin) 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.
Beta-arbutin. Can help to reduce hyperpigmentation and has an anti-oxidant effect when used in high enough concentration. Is less effective compared to alpha-arbutin
Pure 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
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
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.
Evens skin tone
What does the product description say?
The hyaluronic acid in the serum penetrates deep into the skin to combat signs of ageing, while the active ingredients brighten the complexion, even out skin tone and make skin tauter and firmer.

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: arbutin.
Beta-arbutin. Can help to reduce hyperpigmentation and has an anti-oxidant effect when used in high enough concentration. Is less effective compared to alpha-arbutin
Three steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect
Moisturizing
What does the product description say?
111SKIN Celestial Black Diamond Serum also protects the skin from the damaging effects of environmental pollutants, as well as giving the skin a hydrated and plumped up appearance that goes a long way in making it look more youthful, radiant and supple.

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, hyaluronic 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: isopropyl myristate.
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin. Naturally present in skin. Typically has large molecule size unless advertised otherwise on the product label. Helps support skin's barrier function and may help to reduce inflammation

This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.This ingredient - hyaluronic acid - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.
This ingredient arbutin might be able to help neutralize free radicals in skin and help it fight off some of the sun damage.
