What the product description says

“Stretina-RX Cream”

From product name

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: betaine, glycerin.

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: butyrospermum parkii butter, caprylic/capric triglyceride.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol

Irritancy

2 strong irritants: Retinyl palmitate, Parfum

Medium risk

We flagged 15 ingredients with irritancy potential. Severity depends on your sensitivity threshold; the table lists the worst offenders first.

IngredientFunctionIrritationEst. amount

Retinyl palmitateThree steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effectHigh~0.2–0.4%est.

ParfumAn aromatic blend of unspecified and possibly irritating ingredientsHigh~0.05–0.15%est.

Cetyl ethylhexanoateAn emollient that helps soften the skin and creates a thicker product textureMedium~3.1–3.8%est.

Polysorbate 60Helps oil and water mix togetherMedium~0.4–0.6%est.

Tocopheryl acetateA more stable but less bio-available form of vitamin E compared to Tocopherol. Might help moisturize and protect the skin from free radicals, but mostly used in low concentrations to stabilize other ingredients.Medium~0.25–0.45%est.

Glycine soja oilA good emollient that helps soften the skin and helps repair its barrier function. It can clog pores if used in high concentrations.Medium~0.25–0.45%est.

Laureth-23Helps oil and water mix togetherMedium~0.3–0.6%est.

Sodium ascorbyl phosphateA stable derivative of vitamin C. It is oil-soluble which means it is more likely to penetrate the skin compared to the pure form of vitamin C (which is water-soluble), but it is less bio-available and is way less effective in stimulating collagen and reducing wrinkles compared to the pure form of vitamin C (L-ascorbic acid) and its other derivatives (for example, magnesium ascorbyl phosphate). At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin CMedium~0.2–0.4%est.

TriethanolamineUsed to adjust pH of the product and can help improve the product's smellMedium~0.2–0.35%est.

Product summary

Based on the ingredient list, "TOSOWOONG - Stretina-RX Cream" can work well for skin moisturization. As we expect from a proper moisturizer, the formula includes a combo of effective humectants and emollients. These are the two different types of ingredients that are essential for improving the skin hydration and supporting a healthy skin barrier. Panthenol, betaine, glycerin, butylene glycol and caprylyl glycol in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Emollients in this formulation (glycine soja oil, limnanthes alba seed oil, butyrospermum parkii butter, caprylic/capric triglyceride and dimethicone) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.

Ingredient callouts

this moisturizer includes a form of Retinoids (vitamin A) - retinyl palmitate 0.20% - 0.40%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.

This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: sodium ascorbyl phosphate, lecithin, jojoba oil and stearic acid

Irritation risk

This moisturizer contains some common irritants, including those without a benefit for the skin. We assess the overall irritancy of this moisturizer to be medium. For a detailed overview of all potential irritants: click here
