The claim “Vaseline and cornstarch make you a 16-year-old girl no matter how old you are” is false. No topical mixture can reverse aging or make adult skin biologically equivalent to teenage skin.
Here’s what each ingredient can actually do:
- Vaseline (petroleum jelly):
- Forms a protective barrier that helps prevent water loss from the skin.
- Can make skin feel softer and smoother.
- Helps protect dry or irritated skin.
- Does not stimulate collagen production or erase wrinkles.
- Cornstarch:
- Can absorb moisture and oil.
- May leave the skin feeling temporarily smoother or less shiny.
- Provides no proven anti-aging benefits.
- Can irritate some people or worsen certain skin conditions if used regularly.
If you see a video where someone mixes the two, any “younger-looking” effect is usually temporary:
- The petroleum jelly hydrates the outer layer of skin, making fine lines less noticeable.
- The cornstarch creates a matte, blurred appearance.
- These cosmetic effects disappear after washing your face.
For healthier-looking skin with evidence behind it, the strongest options are:
- Daily broad-spectrum sunscreen (SPF 30 or higher).
- A moisturizer suited to your skin type.
- A topical retinoid or retinol, if appropriate.
- Vitamin C serum for some people.
- Avoiding smoking and excessive sun exposure.
So, while Vaseline can be an effective moisturizer, the claim that Vaseline and cornstarch can make someone look like a 16-year-old is not supported by scientific evidence.
