What the product description says

“nourishes”

Source: N/A

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: alanine, arginine.

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: arginine, chondrus crispus extract.

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

Irritation risk: High

Oil of a very fragrant pink rose used as fragrance in cosmetics. Extensive research has shown it has mixed benefits. In the pro column, inhaling this flower’s scent seems to have relaxing properties and the plant’s petals contain skin-soothing and antioxidant compounds that can benefit skin. On the flipside, the numerous chemicals that create this rose’s distinctive fragrance pose a risk of causing skin aggravation.

A polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals

Product summary

Based on the ingredients included, "OSKIA - Rest Day Barrier Repair Balm" works well for moisturizing the skin. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. OSKIA - Rest Day Barrier Repair Balm ticks this box. Panthenol, alanine, arginine, avena sativa kernel flour and betaine 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 (avena sativa kernel flour, helianthus annuus seed oil unsaponifiables, oenothera biennis oil, arginine and chondrus crispus extract) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.

This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: gluconolactone, vitamin e, allantoin, oatmeal extract, butyrospermum parkii butter and caprylic/capric triglyceride
