WHY WE LOVE IT

Gently smooth and refine your skin with the Nine Less 5% Mandelic Acid Serum.

Formulated with 5% Mandelic Acid (AHA), this mild yet effective exfoliating serum works on the surface of the skin to dissolve dead cells, unclog pores, and improve texture without the irritation common to stronger acids. Mandelic acid’s larger molecular size makes it ideal for sensitive or beginner users, or acne-prone skin, helping to brighten dullness, fade dark marks, and support a clearer, more even complexion over time.

The formula is supported by soothing and hydrating ingredients that help maintain balance and keep skin calm while exfoliation takes place. With consistent use, skin looks smoother, clearer, and fresher, and other skincare products absorb more effectively.

This is Level 3: Balanced Exfoliation according to Nine Less's rating system. Can be used daily if you've used acids before; otherwise start at every second day or less frequently if you have sensitive skin.

30ml

What it does: Gently exfoliates dead skin cells, smooths texture, refines pores, brightens dull tone, and helps fade post-acne marks with minimal irritation.

Who it’s for: Perfect for beginners, sensitive skin, combination or acne-prone skin, and anyone wanting a gentler chemical exfoliant that still delivers visible smoothing and brightening results.

Cool
Color: Black
Been wearing these for about ten years! Nothing better to keep a bald head warm than these. The mesh up top lets your head breathe and dissipate heat. I will miss the wider bland then the thin one now because your head does slip out of it instead of it securing comfortably to your scalp! But I don't know maybe the cost of materials dropped the headband width to what it is now! Anyway, still a great piece!

Great product!

Use this under my hard hat to keep from sliding everywhere. I have bought several over the years and this have been my favorite so far. Will definitely buy again.

Good but if the elastic band were wider it would be great
Color: Black
This is a great under helmet or perspiration barrier for the face during heavy spinning workouts. Sadly to avoid an indentation to your forehead, you must wear it inside out because the sewing band is narrow and tight.

Too damn small
Color: Black
Way too small for an adult. It doesn't even fit my 11 year old. Unfortunately I didn't open it immediately or I would have returned it. Now I'm stuck with something nobody in my house can use.
