Skin feels like glass

- This product I have used for nearly 3 months I think it is good for all skin types and fades hyperpigmentation however for individual dark-spots it takes too long to fade them . However I think it's a little sticky at the finish .

Lasts long and smells nice

This serum works magic. I literally felt like it erased spots in a week, and I was completely acne-free.

Helped smooth out my pores

my go-to product when I feel a breakout coming. love how lightweight this ampoule is. It absorbs quickly and helps calm down active breakouts while working on pigmentation over time.

This ampoule is packed with glutathione, vitamin C, and niacinamide — the perfect trio for targeting hyperpigmentation. It’s been helping fade my dark spots and even out my skin tone without irritation.

No scent

I'm not sure if this serum hides dark spots, but it is supposed to. I haven't used it everyday maybe that's why, but it is affordable. There's no scent and it's not sticky.
