Moisturizing

7 ingredients contribute at the levels below

Good evidence

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, caprylic/capric triglyceride.

BORAGO OFFICINALIS SEED OILRole: Key activeA plant oil that is effective in reducing irritation in skin, restore the barrier function and support its hydration~0.35–0.8%

BUTYROSPERMUM PARKII BUTTERRole: Key activeA great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals~1.7–2.6%

CAPRYLIC/CAPRIC TRIGLYCERIDERole: Key activeA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~3.7–5.5%

COCOS NUCIFERA OILRole: Key activeAn emollient. Found to be as effective as a moisturizer for dry skin as mineral oil. Could be comedogenic~1.3–1.9%

GLYCERINRole: Key activeOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~3.9–5.9%

LIMNANTHES ALBA SEED OILRole: Key activeThis oil's cmposition is closest to rapeseed oil. It is a very stable oil and serves as an emoillient~1–1.6%

TRANEXAMIC ACIDRole: Key activeAn amino acid that is effective in reducing hyperpigmentation and evening out the skin tone. It can also help in skin barrier recovery. It is used to treat melasma, especially with injections and when taken orally~0.2–0.75%

Anti-aging

3 ingredients contribute at the levels below

Partial evidence

This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.These ingredients - 3-o-ethyl ascorbic acid, butyrospermum parkii butter - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.

This ingredient 3-o-ethyl ascorbic acid might be able to help neutralize free radicals in skin and help it fight off some of the sun damage.

3-O-ETHYL ASCORBIC ACIDRole: HeroA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~2.7–4.1%

LIMNANTHES ALBA SEED OILRole: Key activeThis oil's cmposition is closest to rapeseed oil. It is a very stable oil and serves as an emoillient~1–1.6%

Evens skin tone

TRANEXAMIC ACID at ~0.2–0.75% delivers this without it being on the label

Quiet bonus

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

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: 3-o-ethyl ascorbic acid.

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.

GlycerinRole: Key activeOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~3.9–5.9%

Caprylic/capric triglycerideRole: Key activeA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~3.7–5.5%

Prunus amygdalus dulcis oilRole: Key activeAn emollient that softens the skin~2.1–3.1%

Butyrospermum parkii butterRole: Key activeA great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals~1.7–2.6%

Cocos nucifera oilRole: Key activeAn emollient. Found to be as effective as a moisturizer for dry skin as mineral oil. Could be comedogenic~1.3–1.9%

Limnanthes alba seed oilRole: Key activeThis oil's cmposition is closest to rapeseed oil. It is a very stable oil and serves as an emoillient~1–1.6%
