"Works wonders..!"

I have been using this along with Cos-IQ's Vit C. Been 2 weeks that I have been following a routine. Day time:- COSIQ 10% Glycol facewash+ COSIQ VIT C+ Cetaphil moisturizer+ Nykaa sunscreen Nighttime:- Cetaphil Face Cleanser+ Cos-IQ Niacinamide+ Moisturizer+ Face oil to seal the deal. It has significantly reduced the dark spots n pigmentation. My skin feels much more moisturized and radiant. First is the before picture and after picture

    "Reduced prominent pores"

    I had prominent pores, as I have oily skin. It has reduced the appearance of pores and reduced oiliness on skin as well.

    Have been using it for 3 weeks consistently in the morning and pores have vanished, skin oiliness has reduced. It takes time to work the magic, but it definitely works. Must try.!!!
