Contains natural ingredients like Apple fruit water instead of plain mineral water to maximize exfoliating and brightening benefits without any irritation It’s the - sodium form - cousin of the famous NMF, hyaluronic acid(HA). If HA does not tell you anything we have a super detailed, geeky explanation about it here. The TL; DR version of HA is that it's a huge polymer (big molecule from repeated subunits) found in the skin that acts as a sponge helping the skin to hold onto water, being plump and elastic. HA is famous for its crazy water holding capacity as it can bind up to 1000 times its own weight in water. The most researched and well-known AHA exfoliant. It gently lifts off dead skin cells to reveal newer, fresher, smoother skin. In larger concentration (>10%) it's a proven collagen booster. An easy-to-formulate, commonly used, nice to have ingredient that’s also called pro-vitamin B5. As you might guess from the “pro” part, it’s a precursor to vitamin B5 (whose fancy name is pantothenic acid).

Formulated with 7% Glycolic Acid (AHA), this Whitehead Liquid gently exfoliates the skin to naturally brighten uneven, dull skin and promoting a faster cell turnover process.

After cleansing, soak a cotton pad and swipe a thin layer of the liquid over the skin, avoiding the eye and mouth area.Choose a product where you know the concentration and pH value because these two greatly influence effectiveness Increases ceramide synthesis that results in a stronger, healthier skin barrier and better skin hydration

I decided to try a leave-on exfoliator rather than an exfoliating cleanser because I noticed I kept getting irritation from exfoliating cleansers. This Cosrx one is really gentle and pleasant. It takes a few minutes for it to absorb into my skin, but afterwards I get very little irritation and my skin texture and pore appearance have definitely improved. Research also shows that it might be useful for wound healing as it promotes fibroblast (nice type of cells in our skin that produce skin-firming collagen) proliferation. BG’s main job is usually to be a solvent for the other ingredients. Other tasks include helping the product to absorb faster and deeper into the skin (penetration enhancer), making the product spread nicely over the skin (slip agent), and attracting water (humectant) into the skin. 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. After cleansing, soak a cotton pad and swipe a thin layer of the liquid over the skin, avoiding the eye and mouth area. For use during the daytime, follow with a broad-spectrum sunscreen rated SPF 30 or greater.Sodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid. Another benefit is the anti-inflammatory abilities. This means that it's great for sensitive, irritation-prone skin. 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.

Pro-Vitamin B5 is a goodie that moisturises the skin, has anti-inflammatory, skin protecting and wound healing properties. Like hyaluronic acid, it is great at holding water and acts as a humectant. This makes it a great skin hydrating ingredient. Hexanediol is a multi-tasker ingredient. It acts as a preservative to increase shelf-life and can aid other preservatives in preventing microbe growth. 1,2-Hexanediol also helps the skin retain moisture as a humectant. The unfancy name for it is lye. It’s a solid white stuff that’s very alkaline and used in small amounts to adjust the pH of the product and make it just right. I love this..the consistency is runnier than I expected so a little goes a long way. I cant use cotton pads so I drop some onto my skin and rub in.Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells. Pump the product onto a cotton pad and gently wipe it across the face, avoiding the lip and eye area For example, in case of AHA or BHA exfoliants, the right pH is super-duper important, and pH adjusters like sodium hydroxide are needed.
