ALL YOUR QUESTIONS, ANSWERED
1. What hair type is the Full Conditioner for?
The Full Conditioner is best for anyone with fine, flat or thin hair.
2. Is the Full Conditioner fragrance-free, vegan-friendly and free from?
The Full Conditioner is vegan, gluten-free, sulfate free (SLS and SLES), and cruelty-free. It is not fragrance-free as it contains a light citrus scent.
3. Is the Full Conditioner safe to use with color-treated hair?
Yes, all Living Proof products are safe for color-treated hair. This means that they are gentle, non-stripping and help prevent color fade.
Can makeup be returned?
Makeup ships free with a 365-day return window. Opened products may have different return conditions — check the return policy.
How do I find the right foundation or concealer shade for my skin tone?
The most reliable method: swatch 2–3 closest shades on your jawline (not the back of your hand — the hand is rarely the same tone as the face) in natural light. The correct shade disappears into skin rather than sitting visibly lighter or darker. For online purchases, use your current foundation shade number as a reference point if you know it. When uncertain between two shades, the lighter one is typically more versatile — it can be warmed with bronzer, while a shade too dark is harder to correct. Quince product pages include undertone guidance (cool, neutral, warm) to narrow the selection.
How do I build a minimal makeup routine with maximum effect?
A four-product minimal routine that covers most skin concerns: (1) tinted moisturizer or light foundation — evens tone without full-coverage weight; (2) concealer — targeted coverage under eyes and on blemishes only; (3) one eye-defining product (mascara or a neutral brow pencil) — the single highest-impact eye product for most faces; (4) a lip product — balm with color for low-effort polish, or a lip stain for lasting wear. Everything else is additive. For those new to makeup, starting with these four and learning one at a time builds skill and prevents the common mistake of heavy layering that reduces rather than improves the overall look.
