标婷维生素E乳

A formulation based on Glycerin and Dimethicone for hydration, but compromised by the presence of Sodium Lauryl Sulfate and Fragrance.

Performance Rating: 2.6

This formula contains solid foundational moisturizers like Glycerin (humectant) and Dimethicone (occlusive), along with fatty acids like Palmitic Acid and Stearic Acid which help repair the skin barrier. Allantoin is an excellent addition for soothing skin. However, the inclusion of Sodium Lauryl Sulfate (SLS) is a significant drawback; SLS is a strong surfactant usually found in cleansers. In a leave-on moisturizer, it acts as an emulsifier but carries a high risk of drying out the skin or disrupting the moisture barrier over time, counteracting the benefits of the moisturizing ingredients.

Safety Rating: 2.3

The safety profile is compromised by several potential irritants. Fragrance is a leading cause of contact dermatitis. Triethanolamine can be sensitizing and has restrictions on concentration. Sodium Lauryl Sulfate (SLS) is a known skin irritant, especially when left on the skin rather than rinsed off. Additionally, Laurocapram is a penetration enhancer, which may inadvertently increase the absorption of the fragrance and SLS, heightening the risk of irritation. Ethylparaben is a safe and effective preservative scientifically, though some users prefer to avoid parabens.

Final Rating: 2.5

This appears to be a somewhat dated or economy formulation. While it covers the basics of hydration with Glycerin, Vitamin E (Tocopheryl Acetate), and Dimethicone, the choice of emulsifiers and additives is poor by modern standards. The presence of SLS in a leave-on product is the primary negative factor, making this product unsuitable for sensitive or dry skin despite its moisturizing claims. It is functional for hardy skin types but outclassed by gentler formulations.

Verdict

This facial moisturizer presents a complex and somewhat contradictory formulation that mixes beneficial skincare staples with ingredients typically considered red flags for leave-on products. At the very top of the list, the product appears promising. It utilizes a classic, effective base of Water, Glycerin, and Dimethicone. This triad is standard for a reason: glycerin acts as a humectant to draw water into the skin, while dimethicone provides a silky, occlusive seal that prevents that moisture from evaporating. The addition of Tocopheryl Acetate (Vitamin E) adds a layer of antioxidant protection, and Allantoin is a welcome inclusion known for its ability to soothe and calm irritated skin.

However, the safety profile of this moisturizer is significantly marred by the inclusion of Sodium Lauryl Sulfate (SLS). SLS is a strong anionic surfactant primarily used in cleansers, shampoos, and detergents to strip away oils and dirt. While it is sometimes used in small amounts as an emulsifier in creams, it is widely regarded as a significant irritant when left on the skin rather than rinsed off. Its presence in a product meant to act as a moisturizer is counterintuitive, as SLS can disrupt the skin’s natural lipid barrier, potentially leading to increased dryness and sensitivity over time.

Furthermore, the formula relies heavily on fatty acids and fatty alcohols, such as Palmitic Acid, Stearic Acid, Cetyl Alcohol, and Stearyl Alcohol. While these ingredients are excellent emollients that provide a rich texture and soften rough skin, they can be comedogenic for certain individuals, posing a risk of clogged pores for those prone to congestion. The inclusion of Laurocapram is interesting; it is a penetration enhancer designed to help other ingredients absorb more deeply. Unfortunately, in this context, it may simply facilitate the deeper penetration of potential irritants like the Fragrance or the SLS found in the mix.

Finally, the product uses Triethanolamine as a pH adjuster and Ethylparaben as a preservative. While generally deemed safe in regulated concentrations, these ingredients, combined with Fragrance, make the overall formula less suitable for reactive skin types. Due to the presence of a known stripping agent like SLS in a leave-on format, this product is difficult to recommend for maintaining a healthy skin barrier.
