“Physicians Formula 24-Karat Gold complexion-enhancing and plumping Collagen Serum with elasticity-restoring Vegan Collagen and complexion-enhancing 24 Karat Gold.”
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 lactate.
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: palmitoyl tetrapeptide-7, palmitoyl tripeptide-1.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1
Anti-agingNiacinamide, Palmitoyl tripeptide-1 + 1 moreWorks well
“Why It's Good for You: Skin-rejuvenating serum with collagen and 24-Karat Gold delivers firmer, plumper and more youthful-looking skin.”
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: palmitoyl tetrapeptide-7, palmitoyl tripeptide-1.
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.
Evens skin toneSide benefit · NiacinamideWorks well
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide
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.
Anti-blemishSide benefit · NiacinamideWorks well
This product can help reduce breakouts and clogged pores because it contains the following ingredient: niacinamide. This ingredient is used for treating acne and can have a noticeable effect.
