Start by using it every other evening to assess tolerance. If your skin adjusts well, you can use it nightly. It is recommended to use sunscreen in the morning.
Purging can occur when starting a new exfoliant, but it usually subsides within 2-6 weeks. If purging is severe or persistent, reduce frequency.
It is not recommended to use strong exfoliants and retinol together, as they can cause irritation. Use them on alternate nights or consult a dermatologist.

I've struggled with dull, textured skin for years. This glycolic acid serum has transformed my face. Within a week, my skin was smoother and visibly brighter. It's strong, so I only use it at night, but the results are amazing. Best purchase I've made in a long time.
Love this serum! It's potent but gentle enough for my sensitive skin if I don't overdo it. My pores look smaller and my skin tone is more even. Plus, at half price it's a no-brainer.
I like the results, but I have to be careful with how often I use it because it can be a bit irritating if I use it daily. I use it every other night and it works well. My skin looks clearer and more refined.
This is my holy grail exfoliating serum. I've tried many others and nothing compares. It smooths out my texture and gives me that glow everyone compliments. The sale price just makes it even better.
The serum is effective – my skin is smoother and brighter. However, it has a strong odor that some might dislike. I also had some initial stinging, but that faded. Overall, good value during the sale.
I've only used it for two weeks and my skin is visibly more radiant. My dark spots are fading too. It's a bit harsh if you use it too often, so follow the directions. Highly recommend!
This serum is too potent for my sensitive skin. Even using it once a week caused redness and peeling. I wanted to like it, but it's not for me. Maybe better for tougher skin types.
I am obsessed with this serum! My skin looks like I've been on vacation. It exfoliates without being too abrasive if you start slow. I've already repurchased twice.
This is a solid exfoliating serum that does what it says. My skin feels smoother and looks healthier. It's a bit pricey normally, but with the discount it's a great deal. Will probably buy again.
Best serum for my acne-prone skin. It cleared my breakouts and faded the marks. My skin is now smooth and glowing. The half-off price is incredible.
