Refine 10 (Glycolic Serum)

Refine 10 is a 10% glycolic acid exfoliating serum designed for skin that's ready for faster, more intensive resurfacing. Where mandelic acid takes its time, glycolic acid — the smallest AHA molecule — penetrates quickly and delivers among the most clinically proven exfoliation results available in topical skincare.

At 10%, Refine 10 sits at the upper end of over-the-counter AHA strength, targeting stubborn texture, deep congestion, dullness, and PIH that lighter acids address more slowly. This is the serum for experienced exfoliant users who have built tolerance and want more aggressive results.

What it does:
- Accelerates cell turnover for visibly smoother, brighter skin
- Deeply exfoliates persistent texture, rough patches, and uneven tone
- Fades post-acne dark marks and pigmentation faster than gentler AHAs
- Stimulates collagen production with consistent long-term use
- Clears surface congestion and keeps pores cleaner

Who it's for:
Refine 10 is best suited for normal-to-oily and combination skin types that have prior experience with AHA exfoliants and can tolerate stronger acids. It is not recommended for sensitive skin, active rosacea, compromised barrier skin, or anyone new to chemical exfoliants — start with Reset (Mandelic Serum) and build tolerance first. Not recommended for darker skin tones without careful patch testing, as high-strength glycolic has a higher PIH risk than mandelic.

How to use:
Apply to clean, dry skin 2–3 nights per week. Wait 5–10 minutes after cleansing before applying (dry skin reduces penetration speed and irritation risk). Do not use on the same nights as other acid exfoliants, retinoids, or benzoyl peroxide. Follow with a hydrating serum and barrier-supportive moisturizer. SPF every morning without exception.

Build-up protocol:
Start at 1–2 nights per week. After 2 weeks of tolerance, increase to 3 nights. For experienced users only: some use up to 4 nights per week with proper hydration support.

Pairs well with:
Balance Wash → Calming Mist → Refine 10 (PM, alternating nights) → Fonte → Repair

Frequently asked questions:

*What's the difference between Refine 10 and Reset (Mandelic Serum)?
Refine 10 uses glycolic acid — smaller molecule, faster penetration, stronger effect, higher irritation potential. Reset uses mandelic acid — gentler, slower, better for sensitive skin and darker tones. Start with Reset if new to acids.

*Can I use Refine 10 if I'm also using Resurfacer (Vitamin A)?
Do not use them on the same night. Alternate: glycolic serum on exfoliant nights, Resurfacer on retinoid nights. Never both simultaneously.
