Don’t fall for these skincare scams
The skincare world is booming. Everywhere you look there’s a new serum, cream, or mask promising flawless, glowing skin. Honestly, I’ve been there myself, scrolling through Instagram or TikTok and thinking, “Oh, maybe this will work for me…”
You buy the product, spend weeks religiously applying it, and… sometimes, nothing happens. You end up wasting your money and, let’s be real, skincare isn’t exactly cheap.
Dermatologists and clinical research repeatedly reveal a sobering truth: Many popular products deliver far less dramatic results than marketing claims, and some barely work at all.
The skin is a complex organ with a carefully balanced barrier, microbiome, and renewal cycle. Any product that claims transformations should immediately raise an eyebrow.
Here are four widely loved skincare products that often fail to live up to the hype.
Collagen face creams for elasticity
Collagen creams are some of the most convincing products in the skincare aisle. The idea sounds simple and logical: If our skin loses collagen as we age, then applying collagen directly should help restore firmness and elasticity.
But skin science doesn’t quite work that way. Research published in the Journal of Cosmetic Dermatology explains that large molecules like collagen cannot easily pass through the outer layer of the skin. This means they don’t reach the dermis where the skin’s collagen network actually lives.
Eye creams
The skin around the eyes is indeed thinner and more delicate than the rest of the face, which is why some dermatologists recommend gentler formulations in that area. However, multiple dermatology sources note that many eye creams do not contain fundamentally different ingredients from regular facial moisturizers, especially when hydration is their sole purpose.
A 2021 review in the International Journal of Women’s Dermatology found that humectants (like glycerin and hyaluronic acid), emollients, and occlusives—the core components of moisturizers—are just as effective around the eyes as they are on the rest of the face when properly formulated. What makes an “eye cream” is often packaging and marketing.
Stretch mark and cellulite creams
Creams promising to erase stretch marks or smooth cellulite are everywhere, but science suggests their effects are limited. Stretch marks form deep in the dermis when collagen and elastin fibers tear during rapid skin stretching, meaning most topical creams—which act mainly on the outer skin layer—cannot prevent or repair the structural damage underneath.
A clinical study published in the National Library of Medicine found that common ingredients marketed for stretch marks, such as cocoa butter or olive oil, do not prevent their development.
Cellulite is also difficult for creams to treat because it forms beneath the skin, where fat pushes against fibrous connective tissue bands. Since most cosmetic products cannot penetrate deeply enough to alter these structures, improvements from topical creams tend to be minimal or temporary. While ingredients like caffeine or retinol may slightly smooth the skin’s surface, they rarely produce lasting reductions in cellulite.
Blue light protection products
A review published in the Journal of Cosmetic Dermatology on blue light protection, ingredients, and testing methods found that no topical “blue light protection” products have been shown to prevent aging or pigmentation from device use.
Moreover, there is no standardized testing for blue light protection in skincare, allowing brands to make claims without the rigorous oversight required for SPF products.
Dermatologists recommend sticking with broad-spectrum sunscreen, which provides well-established protection against environmental stressors rather than paying extra for products marketed specifically for blue light protection.
