You've just found the most famous vitamin C serum in the world of K-Beauty. Formulated with natural ingredients, suited to treat very sensitive skin, this revitalising serum will give you a rejuvenating glow up, thanks to its formula rich in vitamins. It's formulated with 5% concentrated and pure vitamin C, which is an average-high amount! It's suitable for all skin types. At MiiN, we think every skin care routine should include vitamin C to prevent spots and fine lines. But be careful, as this ingredient is rapidly oxidised, so we recommend you keep the serum in its original box. When exposed to sunlight, even if indirectly, it changes colour (it turns yellowish) and smell, and the formula can go bad. We also recommend you use it in the evening — if you use it in the morning, make sure to apply broad-spectrum sunscreen. Don't mix vitamin C with AHAs (like malic, citric, lactic or glycolic acid), as it might cause irritation. An excellent ingredient to pair up with vitamin C is vitamin E: we recommend thehttps://miin-cosmetics.com/mascarillas/313-freshly-juiced-vitamin-e-mask-8809115024046.html in the same routine for best results.
