I think this product is good because it helps firm the skin and improves its elasticity. The collagen leaves the face feeling firmer, hydrated, and smoother. After removing it, the skin looks more even, radiant, and youthful.
I wouldn’t say this product is bad, because it truly delivers what it promises. I didn’t have any irritation, and my skin felt much better after using it. It’s an effective product, and I have no reason to consider it bad.
