Moisturizing
What does the product description say?
Revitalise the complexion with the 111Skin Y Theorem Concentrate, a seven-day skincare program delivering the power of the NAC Y² complex to help hydrate and renew the skin.
Source: SpaceNK US
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, aloe barbadensis extract.
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.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol

Traditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin
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
Anti-oxidation
This product contains antioxidants (pyridoxine) 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.
Might help neutralize free radicals in skin, but evidence of effectiveness in skin is lacking. It might be irritating
Plant extract. Might have some anti-oxidant properties. Can be irritating

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
Anti-aging
What does the product description say?
Designed as an effective seven-day program, the treatment works to repair and rejuvenate damaged skin, reducing the appearance of fine lines and wrinkles, while boosting elasticity for a radiant, renewed complexion.
