My first time using Donginbi products, what can I say? It's been a revelation! Ok, I haven't really taken care of my skin so far and since I'm now on the wrong side of 45 I decided to take the plunge. I have combination skin with a particularly oily T-zone, and after trying some mattifying lotions which made the oiliness worse than before, I just gave up.Skin concerns- very oily skin, small pimples on and around my chin, and deep laughter lines on the sides of my mouth. I really didn't expect to see any changes at the end of the day.With my limited budget I bought this Upgraded Anti-aging Daily Defence Serum EX as well as the Donginbi Red Ginseng Moisture & Firming Facial Emulsion lotion; and twice daily I have applied the serum, then the lotion after cleansing and toning. A little goes a long way.ResultsAfter about a week I started noticing some changes in my skin tone and texture - my face looks brighter, pores definitely are reduced; and best of all the laughter lines are not as deep. My infamously oily T-zone still gets oily but not as quickly and as much. No fresh breakouts on my chin.After 3 weeks -almost smooth chin, and the T-zone has not changed much from week one. The laughter lines are now about an inch and some down from the sides of my nose. They used to reach a little past my bottom lip. If I had known my face would change for the better I would have taken before and after pictures, but I really didn't expect much beyond maybe some well moisturized skin.I am very happy with Donginbi so far, and I am thinking of buying more of the brand's products. Definitely.
