The Ex On The Beach star had shared a snap online of her soaking up the rays in Miami, Florida by the pool, but eagle-eyed fans spotted the low factor oil at the side of the image.
But Megan's now responded via Snapchat, saying: "So apparently skin experts and people are complaining about the fact I'm using factor four out here, but I do actually use a factor 30 too so chill your beans, babes, it's all sweet. I'm safe. Safe sun."
The NHS advises buying sunscreen that blocks both UVA and UVB radiation, with at least 4-star UVA protection and SPF15. (You can read the full NHS guidelines on sun exposure here.)
Megan flew to Florida following the TOWIE series 17 finale last weekend, and has been sharing a slew of photos to social media showing her having a glam, chilled out holiday with lots of shopping, eating out and relaxing by the pool.
Lucky Megan, right?
While she's been having fun in Florida, boyfriend Pete Wicks has been living it up in Mexico on a lads' holiday with friends including James 'Lockie' Lock.
Megan began dating Pete earlier this year and took their romance public when Megan joined TOWIE mid-way through the 17th series.
The series ended last weekend with Megan and Pete making it official and confirming they are very much girlfriend and boyfriend. They also spoke about their separate holidays, saying neither needed to worry as they both trusted each other and only had eyes for each other.
