COSRX Vitamin C 13 20ml - SALE❗️

WAS $160 - NOW $140

- 13% Pure L Ascorbic Acid. We all know Vitamin C is a superstar ingredient with tons of empirical data backing it. It has been shown to build collagen, brighten skin tone and protect against environmental stressors

- This lightweight vitamin C serum is a must have if you are targeting hyperpigmentation (dark spots), dullness/dull tone, textured skin or just want an overall brightening. The lower ascorbic acid percentage allows for daily use and sensitive skin. It also has calming and soothing ingredients to offset any irritation

- The effective power blend of brightening ingredients in the formulation is, Vit C and Tocotrienol (more potent Vit E), which enhances eachother in brightening

- Also a Vit C derivative (3-O-Ethyl-Ascorbic acid) which is a stable gentler form of pure ascorbic acid

- Acetyl Glucosamine is a multi purpose antioxidant that has been shown to fade discolourations, offer skin calming properties, works particularly well with niacinamide at evening out skin tone, and is a derivative of hyaluronic acid but helps the skin make it's own HA naturally. It is also more stable than HA

- Glutathione is a powerful antioxidant that can help brighten skin

- Niacinamide controls sebum and helps brighten hyperpigmentation

- Licorice root extract helps fade hyperpigmentation

- Caffeine wakes up tired looking skin

- Sodium hyaluronate, Pathenol and Squalane hydrates and repairs the skin barrier

- Allantoin calms down any irritation and soothes the skin

- Arginine has antioxidant and hydrating properties

- Adenosine has anti wrinkle effects by smoothening out skin cells

- Use this serum before your sunscreen to boost protection. Can also use it after an acid exfoliator like a salicylic acid toner to increase absorption.

- Since pure Ascorbic acid is unstable when exposed to heat and air, store in a fridge to increase its lifespan. If it has turned dark brown in colour discontinue use as this means it has denatured

- No fragrance, no essential oils, no alcohol denat
