Key Benefits of Earth Harbor Celestine Hydra-Plumping Peptide Serum

 
These are the key benefits you can expect from using Earth Harbor Celestine Hydra-Plumping Peptide Serum:
 

Lightweight Moisturizer Perfect for Combination and Oily Skin

According to CreamScan analysis, Earth Harbor Celestine Hydra-Plumping Peptide Serum is highly moisturizing, with a moisturizing rating of 6.0 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 2.0 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Aloe Barbadensis Leaf Juice (est. ≈6.0%) and Glycerin (est. ≈3.0%).

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

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

A Humectant Boost for Any Skincare Routine

But it’s not limited to combination and oily skin - such a humectant boost 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.

Slight Anti-Wrinkle Efficacy

According to CreamScan analysis, Earth Harbor Celestine Hydra-Plumping Peptide Serum has a slight anti-wrinkle rating of 0.4 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈0.3%), 
 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).
 
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.

Rich in Skin-Protecting Antioxidants

We estimate that Earth Harbor Celestine Hydra-Plumping Peptide Serum is rich (> 3%) in antioxidants, specifically Punica Granatum Fruit Juice (est. ≈80.0%), Aloe Barbadensis Leaf Juice (est. ≈6.0%) and Punica Granatum Seed Oil (est. ≈4.0%).

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, Earth Harbor Celestine Hydra-Plumping Peptide Serum is rich (> 5%) in soothing ingredients, particularly Aloe Barbadensis Leaf Juice (est. ≈6.0%).

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.
