    My favorite serum combo. I’ve started with Think C 15% a couple of months ago and immediately noticed the difference. Think C 25% helps to prevent break-outs, tightens pores, lightens skin pigmentation and adds a noticeable soft glow. Absolutely love it!

    I have been using Think C for over a year now and find it a really gentle product to either use straight up on my face, or mix with a moisturiser and feel a deeper impact. The pump bottle is great, and has an inner semi-pressurised bag that means you get great every last drop from the bottle, which means great value!

    I love this product and I’m a guy. I spend a lot of time outdoors and this really helps my face feel fresh and look good.
