Water is a great solvent. It’s neutral and doesn’t provide any strong positive or negative effects. It just helps components to mix better and to transport active components.
Butylene Glycol is a very popular synthetic alcohol. It helps the product to absorb deeper and faster. It is also a solvent for other ingredients. As for the skin benefits, it helps to attract water and helps to make the skin softer.
Lactic Acid is the most popular and the least aggressive acid among all the AHAs. Unlike Salicylic and Glycolic acids which can irritate your skin, Lactic Acid will hardly cause any problems. The combination of its soft action and effectiveness makes it a real brilliant. It exfoliates dead cells, makes the skin tone even, clears pores, kills bacteria, moisturizes the skin and helps to keep water, helps the cells to produce Hyaluronic Acid. It also works as a strong antioxidant and anti-aging component.
It's a great acid for getting familiar with the world of AHAs. If you want to start using "fruit acids" but struggling for some reason, try to use Lactic Acid first. If your skin accepts it well, you can try stronger acids.

Citric Acid is one of the AHAs and it is a super useful component! It’s a great antioxidant. It acts as a soft peeling that removes dead cells and kills bacteria. It becomes even more effective if used with other cosmetic acids. Combined formulations are more active, but can irritate sensitive skin if used too often. The component can also whiten the skin and remove dark areas.
It can be an irritator due to its naturally lower pH level of 2.2. But manufacturers also use it as a pH adjuster so in most cases you will not have any issues.
Sodium Benzoate doesn’t have any great skincare effects and is used for formulation purposes. It’s a corrosion inhibitor, fragrance ingredient, and preservative. It is not a broad-spectrum preservative and it’s used with other preservatives for good efficiency. It’s safe, but people with eczema or a history of skin allergies should use this component with attention.

Phenoxyethanol
Roles: Fragrance, Preservative
Antiseptic
Phenoxyethanol is one of the most popular preservatives. It kills bacteria and makes the product live longer. Manufacturers like this ingredient because it can dissolve in any liquid, even in oils.
Another purpose of this component is the fixation of aromas in perfumery. Phenoxyethanol is also used as a strong antiseptic and a good antibacterial agent. It is widely used in dermatological cosmetics alongside natural antiseptics such as chamomile, sage, and calendula.
