This product offers a good level of protection against both UVB and UVA rays.

This sunscreen uses organic (so-called "chemical") sunscreen filters. Organic, or "chemical" filters usually provide reliable sun protection and rarely leave a white cast. Sunscreens with organic filters can sting eyes.

This product can be considered "reef safe" because it does not contain the UV filters (oxybenzone and octinoxate) that can be harmful to coral reefs when present in the water in high concentrations.

What the product description says
“The luxurious, non-whitening lotion glides on fast and blends easily, helping to lock in moisture with a unique blend of ceramides and humectant ingredients.”
Source: MD Solar Sciences

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: caprylic/capric triglyceride, dimethicone.

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: ceramide ap, ceramide eop, ceramide np, phytosphingosine

Ceramide apHero· EmollientEffect: HighA type of lipid similar to ceramides naturally present in skin. Helps to soften the upper layer of the skin and supports the skin barrier function to keep it hydrated. Can help to prevent inflammation in skin~1.4–2.1%
Ceramide eopHero· EmollientEffect: HighA type of lipid similar to ceramides naturally present in skin. Helps to soften the upper layer of the skin and supports the skin barrier function to keep it hydrated. Can help to prevent inflammation in skin~1.1–1.6%
Ceramide npHero· EmollientEffect: HighA type of lipid similar to ceramides naturally present in skin. Helps to soften the upper layer of the skin and supports the skin barrier function to keep it hydrated. Can help to prevent inflammation in skin~0.9–1.4%
PhytosphingosineHero· EmollientEffect: HighA type of lipid that is naturally present in skin. It might help in repairing skin barrier function and has anti-bacterial effect~0.8–1.25%
DimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~23–34%
Caprylic/capric triglycerideKey active· Emollient, OcclusiveEffect: HighA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~7.1–10.6%
Dimethicone crosspolymerKey activeEffect: MediumUsed to create a thicker product texture. Helps soften the upper layer of the skin and might be able to prevent moisture loss from its surface~5.9–8.8%

Camellia sinensis leaf extractEffect: LowCan contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation~0.5–1.15%

This product contains antioxidants (camellia sinensis leaf extract, punica granatum extract) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.

    This was smothering feeling and really irritated my skin. I might have an allergy/sensitivity to one of the ingredients but still didn't like how heavy it felt on my skin. Had to return it after a couple uses.

  • Kathybama· Sep 2022Recommends

    This is my favorite sunscreen to wear under makeup. It is very moisturizing. If you have dry skin you will like this.

  • Matahari· Jul 2022Recommends

    I also like the feel of the application of this sunscreen. Very “silky,” smooth, and not greasy or oily.

Product summary

We believe that this product can provide reliable sun protection based on the ingredients listed. It can protect from both UVA and UVB rays. This is great news because not all sunscreens with SPF ratings give UVA protection. (UVA rays do not cause sunburn, but still damage our skin and lead to early aging).

Because it includes good moisturizing ingredients, it can also work as a hydrating day cream. This product prevents early signs of aging by protecting against sun damage (all broad spectrum sunscreens do that).

Sunscreen filters

This sunscreen uses a mixture of both mineral and organic (so-called "chemical") UV filters. The organic filters in the product are: polysilicone-15. As for the mineral filters, this sunscreen uses both polysilicone-15.

Irritation risk

There are some common irritants in this product, including ingredients that do not have benefits for the skin. We assess the overall irritancy of this sunscreen to be low. For a detailed overview of all potential irritants: click here
