What the product description says
“Made with highly active tetrahexyldecyl ascorbate (AKA supercharged Vitamin C), this serum supports collagen and evens skin tone.”
Source: Dr Loretta

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

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.

Tetrahexyldecyl ascorbateKey activeEffect: HighBeing a lipid soluble form of vitamin C, it is more stable than ascorbic acid, but still degrades quickly and needs to be stabilized in a formulation with another ingredient. It is claimed to penetrate skin better than pure vitamin C and have the the similar benefits, but solid studies of its effectiveness are lacking. Is likely to require a higher concentration in a product than pure vitamin C to be effective. It might be able to help reduce pore clogging.~4.3–5.3%

What the product description says
“Even your skin tone by tightening, toning, and reducing the appearance of fine lines with Antioxidant Repair Serum.”
Source: Dr Loretta

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

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.

What the product description says
“Paired with organic lilac stem cells that balance oily skin and firming marine algae extracts to boost hydration, you’ll be surprised at how effective antioxidant serums can be.”

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, sodium hyaluronate.

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, dimethicone.

GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~4.7–5.8%
Caprylic/capric triglycerideKey active· Emollient, OcclusiveEffect: HighA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~3.4–4.2%
DimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~1.9–2.3%
CyclopentasiloxaneKey active· EmollientEffect: MediumA silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on the skin~1.5–1.8%
Helianthus annuus seed oilKey active· Emollient, OcclusiveEffect: HighA great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function~0.25–0.5%
Undaria pinnatifida extractKey activeEffect: HighA seaweed extract that helps attract water to the upper layer of the skin and might have an anti-oxidant effect~0.25–0.45%
PhospholipidsKey activeEffect: MediumEmollients that are naturaly present in skin. In addition, they help water and oil mix together in the product~0.25–0.45%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.15–0.25%

Side benefit · Tetrahexyldecyl ascorbate, Tocopheryl acetate + 4 more
Works well

This product contains antioxidants (tetrahexyldecyl ascorbate) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
