What the product description says
“Instantly hydrating, cooling and refreshing, Mustela After Sun Lotion spray offers skin a boost of moisture after it’s been exposed to the sun.”
Source: Escentual

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: simmondsia chinensis seed oil, persea gratissima fruit extract.

Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).

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

Product summary

"Mustela - After Sun Lotion" is a well-rounded moisturizing product. The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Butylene 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 (paraffinum liquidum, persea gratissima fruit extract, simmondsia chinensis seed oil, dicaprylyl carbonate and glyceryl caprylate) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.

Irritation risk

This formulation includes some common irritants, including ingredients that do not provide 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
