Grapeseed extract in sunscreen could have anti-ageing benefits for Asians – Thai study

The addition of grapeseed extract in a sunscreen formulation has been found to have anti-ageing effects on Asian skin, improving the overall youthful appearance of skin.

It was noted that skin elasticity was difficult to determine given intrinsic and extrinsic factors including age.

Based on this review, the S. macrophylla​ seed extract could be an agent for anti-ageing and is photoprotective when tested across the UVA and UVB spectrum.

The extract could also potentially reverse UVB-induced damage because of its antioxidant and anti-inflammatory properties as shown in previous studies.
