@natalie_oneillll: You can have both dehydration lines and/or forehead lines from repeated movement, even in your early to mid twenties. This is completely normal, but many still want to improve the appearance. In the first instance, especially if they're simply dehydration lines. here's what to try: 1. Make sure you have a hydrating serum in your routine. So many people have tonnes of acids/exfoliants, but no simple hydrators. This should be separate from a moisturiser. 2. Make sure your routine isn't overly drying, even with a hydrating serum. For example, reducing exfoliation from 2-3x a week to 1-2x can help here. 3. Always wear sunscreen so to protect your skin generally, but also to prevent premature collagen breakdown from sun exposure, which can contribute to premature ageing. ib @ large baj
