Why Sunscreen Alone Won’t Stop Your Tan - Rashmi Shetty Explains

“Applied sunscreen but still got tanned?” If that’s you, you’re not alone! In a recent instagram post, celebrity dermatologist Rashmi Shetty explains why sunscreen sometimes fails and what you might be missing. From common mistakes like under-applying to skipping reapplication, she shares how to protect your skin better, both from the outside and from within.

A single morning application isn’t enough. Sunscreen loses its effectiveness with time, sweat, and exposure. To stay truly protected, you must reapply every 2-3 hours, especially if you’re outdoors, at the beach, or even driving. Consistency is the golden rule of sun safety.

Most people apply only a pea-sized amount, which is far less than required. The correct quantity is the two-finger rule, one strip of sunscreen along your index finger and one along your middle finger. This much ensures your face and neck are fully covered and safe from UV rays.

Think sunscreen is only for sunny days outdoors? UV rays easily filter through glass windows and even on cloudy days, about 80% of UV rays reach your skin. That’s why dermatologists, including Shetty, insist that sunscreen must be applied daily, indoors and out, 365 days a year.

Not all sunscreens are made equal. SPF mainly protects against UVB rays that cause burns and tanning, while PA+++ or UVA circle logos defend against UVA rays responsible for pigmentation and premature aging. Always look for broad-spectrum sunscreen that covers both UVA and UVB for complete protection.

You might come across “TPA” on sunscreen products. While it isn’t an official scientific rating, it generally points to a product’s tan protection ability. The higher the SPF and UVA protection, the better the defense. Still, remember: sunscreen only prevents further tanning, it doesn’t remove the tan you already have.

Topical protection is just one part of the puzzle. Rashmi Shetty highlights the importance of internal care through supplements. They act as an “inner sunscreen,” neutralizing damage from UV rays, regulating pigmentation, and strengthening your skin barrier. This combined approach offers longer-lasting, all-round protection.

Skin supplements can be smart add-ons to your daily routine, offering targeted support for healthier, more resilient skin. RA Defense is rich in antioxidants that work to combat UV-induced free radicals, protecting skin from environmental damage, RA Vitamin C+ enhances collagen production, strengthens the skin barrier, and improves overall skin resilience, giving you a radiant and well-protected complexion.
