Ingredients higher up in an ingredient list are typically present in a larger amount.
Retinol is a gold-standard ingredient for anti-aging. It is a form of Vitamin A and belongs to the class of retinoids that also includes tretinoin.
Why is retinol famous?
It has the most scientific studies backing up its skin benefits out of all the non-prescription ingredients.
Retinol is proven to:
This is why retinol is effective at removing wrinkles, fading dark spots, treating acne, and reducing the appearance of pores.
Studies show retinol is less effective when exposed to UV. Be sure to look for appropriate packaging to keep your retinol potent (similar to Vitamin C).
Using retinol or any retinoids will increase sun-sensitivity in the first few months. Though studies show retinoids increase your skin's natural SPF with continuous use, it is best to always wear sunscreen and sun-protection.
We recommend speaking with a medical professional about using this ingredient during pregnancy.
Retinol may cause irritation in some people, so be sure to patch test. Experts recommend 'ramping up' retinol use: start using this ingredient once a week and work up to using it daily.

As a surfactant, it helps collect dirt and oils for washing. Emulsifiers prevent oils and water from separating.
Polysorbate 20 also adds scent to a product. Since it is made using sorbitol, it has a sweet scent. Sorbitol can also be found in fruits such as apples and peaches.
The lauric acid used to create Polysorbate 20 is often derived from coconuts.
Polysorbate 20 may not be fungal acne safe.

This was genuinely one of those products that I'm not sure if I noticed any results. Aside from the uncertainty of this product and the ingredients. I also did not enjoy the consistency of this serum. It felt as if it never fully absorbed and made my skin feel rather oily. Not sure about the other products from this brand, but I feel unlikely to repurchase this.
UPDATE: their homepage actually says that it’s not retinol 2.5% but only 0.13%. That low percentage does nothing for your skin 😂 For me it’s misleading advertising and I have read they do that a lot with their products. Hence I m not buying anything more from them. Also in Germany a product that contains over 1% Retinol is considered medical care and usually needs prescription (EU regulations). So Show more
