WIMJ summary

This product offers broad spectrum sun protection, but it is weak. We recommend to use a broad spectrum sunscreen with at least SPF 30.

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.

WIMJ summary

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

WIMJ summary

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

This product can also help with skin tone because it offers sun protection. Sun damage is the main factor causing age spots, darkening of post-acne marks and other discolorations. This is why sun protection is the best strategy for maintaining an even skin tone. We, however, do not recommend using this product as a sunscreen because the protection it offers is not strong enough).

WIMJ summary

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: 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, dimethicone.

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