Key Benefits of Goop Beauty Youth Boost Peptide Serum

 
These are the key benefits you can expect from using Goop Beauty Youth Boost Peptide Serum:
 

Lightweight Moisturizer Well-Suited for Combination and Oily Skin

According to CreamScan analysis, Goop Beauty Youth Boost Peptide Serum is quite moisturizing, with a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 2.3 out of 10 and a high humectancy of 7.8 out of 10, primarily due to the high content of Glycerin (est. ≈3.0%) and Niacinamide (est. ≈2.0%).

This type of moisturizer is well-suited for people with combination and oily skin who want significant hydration in a relatively lightweight, non-greasy formula. It combines a substantial amount of humectants with a limited amount of occlusive to enhance moisturizing efficacy without feeling too heavy.

This product may also be an option for people with normal skin who prefer fast-absorbing textures, as it balances significant moisturizing potential with a relatively lightweight texture.

A Humectant Enhancement for Any Skincare Routine

But it’s not limited to combination and oily skin - such a humectant enhancement will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Modest Anti-Wrinkle Efficacy

According to CreamScan analysis, Goop Beauty Youth Boost Peptide Serum has a modest level of anti-wrinkle efficacy, rated 3.0 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈2.0%), 
 one of the most effective and well-researched anti-wrinkle ingredients. A clinical study involving 30 participants (Kawada et al.) confirmed that a cream with 4% niacinamide reduced the average depth of wrinkles around the eyes by 9% after 8 weeks of use, compared to a vehicle (the same formulation without niacinamide).
 
Among others, Goop Beauty Youth Boost Peptide Serum also contains Gluconolactone, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Gluconolactone provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not contribute to the anti-wrinkle rating.
 
Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, can deliver some anti-wrinkle effects through its moisturizing action.
 

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

Rich in Skin-Protecting Antioxidants

We estimate that Goop Beauty Youth Boost Peptide Serum is rich (> 3%) in antioxidants, specifically Carthamus Tinctorius (Safflower) Oleosomes (est. ≈4.0%) and Niacinamide (est. ≈2.0%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.

Skin Soothing and Calming Potential

Based on the ingredient list analysis, Goop Beauty Youth Boost Peptide Serum is rich (> 5%) in soothing ingredients, particularly Bifida Ferment Lysate (est. ≈6.0%) and Niacinamide (est. ≈2.0%).

When applied to the skin, compounds of soothing ingredients, such as triglycerides, phospholipids, fatty acids, phenolic compounds, and antioxidants, work together to soothe the skin through various mechanisms: reducing inflammation, promoting wound healing, repairing the skin barrier, and providing antimicrobial and antioxidant activities.

Please note that this is not a complete list of benefits. We are in the process of enhancing our AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.
