Q1. How long does the hydration last?
A. Through the day for most skin — hyaluronic acid draws water in, ceramide NP and panthenol keep it there. Very dry skin can layer a cream on top at nightafter the gel melts in.
Q2. Is the cooling effect irritating?
A. It's a physical cooling effect from erythritol, xylitol and eucalyptus, not a tingling active. Skin surface temperature dropped 8.9°F immediately after use intesting,* and the formula scored 0.00 on a primary irritation test. If you react to eucalyptus, patch-test first.
Q3. Can I use it after sunburn or a long day in the sun?
A. Yes — it's the after-sun step: a generous layer before bed as an overnight cooling mask. Avoid blistered or broken skin.
Q4. Should I keep it in the fridge?
A. You can — chilling the gel (and your gua sha or roller) makes the cooling even stronger. Keep it above freezing.
Q5. Does it leave residue or feel sticky?
A. It has the lightest texture in the Booster Gel line. Like the others, give it 3–5 minutes to melt in — no wiping needed.
Q6. Does it work with facial devices?
A. Yes: gua sha, rollers, ice globes and microcurrent devices. The cool glide is a favorite with chilled tools.
Q7. Which skin concerns is it best for?
A. Dryness, tightness, heat and redness after sun, morning puffiness, and dehydrated combination skin. If your main concern is oiliness, look at Phyto-PDRNinstead.
