Is this gentle enough for daily use?

This is a results-driven exfoliant designed for regular use, not a peel. The combination of AHAs and BHA smooths and refines skin, while ceramides, squalane, and polyglutamic acid help support hydration and barrier function so skin doesn’t feel stripped over time.

How often should I use the AHA + BHA Milk Serum?

Start with 2–3 nights per week, then work up to nightly use as your skin adjusts. Apply to clean, dry skin in the evening and follow with moisturizer if needed.

What did the clinical study actually show?

We commissioned an independent 8-week clinical study at Essex Testing Clinic (30 participants). Here is everything it showed: 93% reported smoother, softer skin 97% said it's gentle enough for everyday use 97% skin looked softer 93% saw improved skin clarity 93% skin looked brighter 90% pores looked smaller / more refined

Can I use this if I have sensitive, dry, or combination skin?

Yes. This formula pairs exfoliating acids with ceramides, squalane, and polyglutamic acid to support the skin barrier during use. If you’re new to exfoliation, we recommend starting slowly and adjusting based on how your skin responds.

Can I use this with vitamin C, retinoids, or other active products?

Use this at nightAvoid layering with other exfoliating acids or retinoids in the same routineVitamin C is best used in the morning, exfoliation at nightWhen in doubt: alternate nights

My Holy Grail for Exfoliation

I have combo skin that changes with the seasons. I’m oilier in the summer and drier in the winter, so I like to keep my routine gentle and balanced without using too many actives. My goal is graceful aging, and I feel like overdoing strong ingredients can backfire. I use this once a week and have had no irritation, which makes me even more interested in it. It makes my skin feel really soft, gives me immediate hydration, and even seems to help with blackheads. Milky serums and cleansers are already my favorite, so this really appeals to me. The non-toxic, natural angle makes it even better. Give it a try! 😇
