Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.

A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.

As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.

Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.

Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.

In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.

This ingredient is organic, colorless, odorless, and non-toxic.

Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

What it does: Smoothing
Community Rating: Loved

Niacinamide has emerged as an all-star ingredient due to its many benefits.

It is known to treat acne by reducing inflammation. It also helps fade dark-spots and strengthen the skin by promoting the growth of the ceramide barrier.

Other benefits include smoothing wrinkles and minimizing redness.

The cherry on top? Niacinamide can also help build keratin, a protein that keeps skin firm.

When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.

Niacinamide can be mixed with other ingredients to boost benefits. For instance, it has shown to be effective when used with copper, folic acid, and zinc to treat acne.

What it does: Skin Conditioning

Retinol is a form of Vitamin A and proven to help with anti-aging.

It promotes collagen production, increases new cell turnoever, and protects your skin as an antioxidant.

Retinol boosts collagen production and increases cell turnover. This makes retinol effective in removing wrinkles, fading dark spots, and reducing the appearance of pores.

Retinol is less effective when exposed to sun. Be sure to look for appropriate packaging to keep your retinol potent.

Using retinol and retinoids will increase sun-sensitivity in the first few weeks of use. 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.

Very good and gentle retinol serum
My retinol journey began with this gentle serum with a concentration of 0.3% retinol: 0.1% pure retinol combined with 0.2% retinol palmitate that ensures gradual release of the active ingredients. It din't irritate my skin or cause any major break-outs, just some slight purging in the beginning, but that is concidered a normal reaktion that fades as soon as the skin gets used to it. I recommend it for retinol beginners and people with sensitive skin. [Edited]
