Can I use these pads morning AND evening?
Yes, provided you apply SPF 30+ in the morning. The pure 99% retinol remains at 500 ppb (0.0005%), a gentle concentration that allows twice-daily use. If you notice redness or tightness, limit use to nighttime on accustomed skin.
What is the difference compared to a classic retinol serum?
The pad distributes the active ingredient evenly thanks to liposomal impregnation, whereas a serum concentrates locally. The micro-net stretch fabric fits contours (temples, jawline) for targeted treatment without waste. Plus, you get gentle mechanical exfoliation + anti-aging actives.
How long does a jar of 100 pads last?
Daily toner use: about 3 months. Intensive mask use 3 times/week: 8 to 10 months. Each pad is sufficiently soaked to treat both face AND neck.
Can I combine them with a vitamin C serum in the morning?
Yes, but in the right order: after the pad (slightly acidic pH favorable to retinol), wait 2-3 minutes, then apply your vitamin C serum if its formulation is stabilized (derivatives like SAP or THDA). Avoid pure L-ascorbic acid the same day if you are just starting.
Are the pads suitable for sensitive skin?
According to MEDIHEAL hypoallergenic tests, yes — but retinol remains an exfoliating active. Start with 2 applications/week in the evening on clean, dry skin. If no reaction after 10 days, gradually increase. Avoid if you have atopic dermatitis flare-ups.
Should I rinse after using the pad as a toner?
No. The essence must penetrate so the actives (300 Dalton collagen, ceramides) can work. Gently pat excess without rubbing, then continue your routine. If sticky, you are using too much product afterward — lighten your following layers.
