📍넘버즈인 글루타치온C 흔적 필름패드 이 제품 추천드릴게요! 순도99% 글루타치온에 젤리면,거즈면으로 나뉘어져있어서 젤리면으로 5분 정도 부착해주면 확실히 얼굴 안색이 밝아지는게 느껴졌어요ㅎㅎ 민감성이신 분들도 사용 가능해요!
Has anyone seen whitening effects from Vitamin C products?
Vitamin C is consumed or applied topically.
For some reason, I felt that topical Vitamin C was a bit irritating.
I think it's because Vitamin C is an acid.
I stopped using it after only applying a sample because I was more concerned about skin troubles before I could see any whitening effects.
To achieve a whitening effect with Vitamin C products, what is the proper way to apply them, or what are some skin-friendly products?
