Venus, 43, also turned heads in a stunning dress with a colorful ombre pattern and wavy hemline.

The multi-talented sisters had some fun trying on the new products, with Serena applying some makeup onto her sibling.

Venus also touched up her lips with a swipe of Serena’s lip gloss.

WYN Beauty officially launches on April 7 and includes mascara, lip serum, lipstick, concealer, eye makeup, and SPF-infused skin enhancing tint.

Serena founded and developed the beauty collection as ‘makeup you can move in,’ according to the company’s website.

WYN Beauty was inspired by Serena’s own post-match glam routine; the tennis pro was forced to quickly wash her face and apply makeup before speaking with the press after a game.

‘Those moments are the foundation of the brand,’ Serena recently told Brydie magazine.

‘After playing on center court in front of millions of people, I’d have to do press. There was a point where I was talking to the press every single day.

‘I had to figure out how I wanted to show up, but I only had a few minutes after a match to do my makeup.’

WYN Beauty’s first line consists of 10 items including skin tint, concealer, eyeliner and combined lip and cheek color which were Serena’s go to makeup items for those quick post match refreshes.

‘It all started with the skin tint,’ she shared. ‘I would often mix my foundation and sun cream because I couldn’t find a skin tint I loved.

‘I realized that if I’m having this problem, other people are as well. I also remember talking to beauty publications, and they’d ask me about the products I couldn’t live without.

‘I’d list products like eyeliner and lipstick, which I often used on my lips and cheeks. From there, I started thinking about how I could create functional and really cool products,’ she explained.

The brand has taken five and a half years to develop and contains vegan, cruelty-free products.

‘I wanted to create [a collection] people could use every day to enhance their natural beauty,’ Williams said. ‘I wanted to focus on long-wearing, “clean” formulas because that’s how I live my life. I have a farm and try to eat clean, so I also apply that approach to what I put on my face.’

These days, the Grand Slam winner isn’t working out as much as she used to but she’s just as active as a mom to two young daughters.

‘For me, it’s about creating a collection that speaks to me, whether I’m on the tennis court or picking my daughter up from school,’ Serena explained.

‘A little goes a long way with what we’ve created with WYN Beauty. If I wake up late, I can quickly put on our skin tint, concealer, and lip and cheek tint and look fully made up all day.

‘WYN Beauty wants you to understand you can be glamorous and active—and own it.’
