The 3 antiaging products everyone should start using after they turn 30, according to a celebrity facialist

• Celebrity facialist Candace Marino told BI the products people should use when they turn 30.  
• She said retinol is the "gold standard for antiaging" and can help acne. 
• Marino believes "neck cream is the new eye cream" and should be started earlier than you think.

Hyaluronic acid, niacinamide, tretinoin — if these words mean nothing to you, you're definitely not on skincare TikTok.

The popular app has become awash with clips filled with antiaging tips and tricks, and trying to decipher which routine is right for you might feel harder than chemistry class did.

But please, put the phone down. Candace Marino, a celebrity facialist, told Business Insider that the most common mistake she sees people make when starting an antiaging regimen is "piecing together a routine based on a TikTok or an influencer."

"Skin is our largest organ and should be respected as such," said Marino, whose clients include Kourtney Kardashian and Miranda Kerr. "Learning about beauty products online is fun, but what worked for your favorite influencer may not necessarily be good for you."

Marino recommends consulting with a facialist or skincare professional to develop a customized routine, but there are three products she believes everyone should start using once they turn 30.

Daily sunscreen is a no-brainer

"SPF is the most important antiaging product that everyone should be using daily," Marino said. "Without SPF, you're wasting money on all the other skincare products. It's like spending the money on a Ferrari and not insuring it."

Marino's "all-time favorite SPF" is the iS Clinical Extreme Protect SPF 30, which she said is "like a three-in-one product."

"It's packed with antioxidants to protect the skin, it's incredibly moisturizing, and it has SPF 30," she added.

Marino's other favorites include the Jan Marini Antioxidant Daily SPF 33 and Supergoop Glowscreen SPF 40, which she calls an "instant glow in a bottle."

Retinol can help both aging and acne

Retinol is frequently mentioned on skincare TikTok, and Marino says it's worth all the hype.

"Retinol is the gold standard for antiaging and is also a powerful anti-acne ingredient," she told BI. "Many women in their 30s experience acne for the first time due to hormonal shifts. Retinol will speed up cell turnover, preventing accumulation in the pores that plugs them and causes acne."

Marino recommends the SkinBetter AlphaRet Overnight cream for "all first-time retinoid users and anyone who wants to keep their skin youthful."

"This was the first retinol I was ever able to use," she said. "This formula is as effective as prescription tretinoin, without all the side effects."

Marino is also a fan of Jan Marini Age Intervention Duality MD, which is her favorite retinol for acne.

"This is retinol plus benzoyl peroxide — two superstar ingredients to treat and prevent acne," Marino said. "I've never seen a product clear up acne faster."

You should start using a neck cream earlier than you think

"Neck cream is the new eye cream," Marino told BI. "I recommend starting it before you actually see signs of aging on the neck."

"With the rise of social media, many women are complaining about tech-neck," she added. "Using a good neck cream will help strengthen the tissue and prevent deep line formation and laxity."

According to Marino, the best neck cream on the market is the Techno Neck Perfecting Cream from Skinbetter.

"This neck cream increases tissue nitric oxide uptake, which helps improve circulation to the area — warranting a tightening effect," Marino explained. "My clients will use this for the first time and call me three days later and be like, 'I swear I see a difference.'"
