Many factors contribute to the visible signs of ageing. On the surface of our skin, environmental aggressors, such as Australia’s harsh climate of heat, humidity, drying air and smog. It all can impact our skin’s protective barrier, leaving it drier and vulnerable to fine lines, wrinkles and premature ageing. In the deeper layers of our skin, the skin’s building blocks, such as collagen and elastin, decline over time, resulting in fewer oils and lower hydration. Hormonal changes can add to the mix, making skin thinner, drier, and less resilient over time.
At Dr. LeWinn’s, we understand you want to look and feel your best at any age. That’s why our formulations use scientifically tested ingredients and advanced key ingredients like peptides.
What are peptides?
You can think of peptides as tiny messengers that can remind the skin to do what it naturally does best: protect, renew, and revitalise. They’re short-chain amino acids, the same building blocks that make up proteins like collagen and elastin. Peptides work to help maintain the skin’s protective barrier and skin hydration.
