up&up Sensitive Skin Body Lotion - Fragrance Free

A robust, fragrance-free formula combining Ceramides, Amino Acids, and Petrolatum to deeply hydrate and restore the skin barrier.

Performance Rating: 4.8

This formula is exceptionally well-engineered for hydration and barrier repair. It features a complete Natural Moisturizing Factors (NMF) profile, including Urea (Hydroxyethyl Urea), Sodium PCA, and a comprehensive list of Amino Acids (Serine, Alanine, Glycine, etc.), which naturally hold water in the skin. The inclusion of the ‘golden ratio’ of lipids—Ceramides (NP, AP, EOP), Cholesterol, and Phytosphingosine—is crucial for restructuring the skin barrier. Furthermore, Petrolatum and Dimethicone provide superior occlusive properties to prevent transepidermal water loss (TEWL), while Glycerin and Sodium Hyaluronate ensure deep hydration.

Safety Rating: 4.5

The safety profile is excellent, particularly because it appears to be fragrance-free, significantly lowering the risk of irritation for sensitive skin. The preservatives used (Phenoxyethanol, Ethylhexylglycerin) are standard and safe. While Petrolatum and PEGs (PEG-100 Stearate) are highly effective and safe for skin use, they are synthetic ingredients that some users preferring strictly ‘natural’ products may avoid, though this does not detract from their clinical safety. Sodium Hydroxide is present merely as a pH adjuster and is safe in the final formulation.

Final Rating: 4.7

This is a top-tier body moisturizer that rivals high-end dermatological brands. It successfully bridges the gap between heavy-duty occlusion (thanks to Petrolatum) and advanced skin repair (thanks to the Ceramide complex and Amino Acids). The addition of Tapioca Starch is a smart formulation choice to mitigate the greasy feel often associated with intensive moisturizers. It is an ideal choice for dry, compromised, or eczema-prone skin.

Verdict

This body moisturizer represents a sophisticated approach to skin hydration, focusing heavily on barrier repair and mimicking the skin’s natural biology. At its core, the formula relies on a classic, reliable base of Water, Glycerin, and Petrolatum. Petrolatum is widely considered the gold standard of occlusives, preventing transepidermal water loss more effectively than almost any other ingredient. However, to ensure the product doesn’t feel overly greasy or sticky, the inclusion of Dimethicone and Tapioca Starch provides a silky slip and a matte finish, improving the overall cosmetic elegance.

What truly elevates this moisturizer is its impressive array of skin-identical ingredients. It features a comprehensive Ceramide complex (Ceramide NP, AP, and EOP) paired with Phytosphingosine and Cholesterol. This trio is essential for maintaining the “mortar” between skin cells, making this an excellent choice for individuals with compromised barriers or conditions like eczema. Furthermore, the inclusion of Sodium Hyaluronate and Hydroxyethyl Urea ensures deep water retention within the stratum corneum.

The formulation goes a step further by incorporating a blend of Natural Moisturizing Factors (NMFs), including Sodium PCA, Sodium Lactate, and a long list of Amino Acids like Arginine, Glycine, and Proline. These ingredients work synergistically to maintain hydration elasticity and overall skin health. The absence of fragrance and drying alcohols makes it a safe haven for sensitive skin types.

While the formula is non-comedogenic for most, the presence of Isopropyl Palmitate and Petrolatum might be too heavy for those prone to body acne (such as “bacne”). However, for the vast majority of users dealing with dryness, flakiness, or sensitivity, this ingredient list is top-tier. It strikes a difficult balance between being heavy-duty enough to heal cracked skin and cosmetically elegant enough for daily use.
