Guru spotlight: Skin Obsessed Mary, and the products she rates highest

Skin Obsessed Mary has reviewed 328 products in The Guru Index, and she knows her way around a serum. Most often, in fact: 54 of her reviews cover serums, the category she digs deepest into.

Who is Skin Obsessed Mary?

Mary is an American living in Dublin, Ireland, who started sharing her skincare journey on social media during the Covid lockdown to connect with other enthusiasts. By day she works in marketing, but her real expertise comes from lived experience. At 15, a car accident left her with facial scarring, and she went through a series of plastic surgeries to address the damage. Through high school, she relied heavily on makeup to cover the marks, until she made peace with them and shifted her focus entirely to skin care instead. Now at 55, she says she has the best skin of her life, though she still carries a few wrinkles and age spots from sun exposure in the 1970s without sunscreen. Her mantra is simple: less makeup, better skin care.

Which products does Skin Obsessed Mary rate highest?

Three of Mary's top-rated products also earn strong support from the wider panel of experts. The Bioderma Sensibio H2O Micellar Water carries a Guru Score of 96%, and Mary said she prefers Bioderma's version. The Ordinary Lactic Acid 10% + Hyaluronic Acid scores 95%, and she reports she used it every day for years as a great product. La Roche-Posay Cicaplast Baume B5 scores 93%, and Mary calls it highly effective, saying she has relied on it for all of the skin stresses she has faced over the years.

Where does Skin Obsessed Mary disagree with the other experts?

One place Mary breaks from the wider expert consensus is the EltaMD UV Clear Broad-Spectrum SPF 46, which the other experts rate highly at a Guru Score of 82%. Mary passed on it, noting it was her first real sunscreen and dermatologist recommended, but she has not repurchased it. She points to the simple fact that so many more options exist now, plus the product is kind of hard to find and she heard they reformulated. One trusted voice matters most when you are starting out, but the Guru Score tells you whether the rest of the panel agrees. Mary's full takes are worth reading on her guru page to see which products earned her stamp of approval and which did not quite make the cut.
