Dot & Key Vitamin C + E Sunscreen SPF 50+ (50g)

Dot & Key Vitamin C + E Sunscreen SPF 50+ PA++++ with New-Age UV Filters — 50g

This is the upgraded version of Dot & Key's Vitamin C sunscreen line — same brightening actives, but with a more advanced UV filter system that delivers higher photostability and a cleaner, more fluid finish. Where older sunscreen formulas rely on basic chemical filters that degrade in sunlight, the new-age filters here (Uvinul A Plus and Uvinul T 150) maintain their protective efficacy throughout the day without breaking down. Combined with a triple Vitamin C blend and Vitamin E, it protects against future UV damage while actively correcting existing dullness and pigmentation.

At a Glance

What It Does

Two things happen simultaneously with each application: the UV filters block incoming radiation, and the antioxidant actives work on existing damage. This dual-direction action is what separates a brightening sunscreen from a standard one.

New-Age UV Filter System

Most basic sunscreens use first-generation chemical filters like Ethylhexyl Methoxycinnamate, which absorb UV energy but degrade relatively quickly in sunlight — meaning protection weakens throughout the day. This formula uses photostable next-generation filters: Diethylamino Hydroxybenzoyl Hexyl Benzoate (Uvinul A Plus) for UVA, Ethylhexyl Triazone (Uvinul T 150) for UVB, and Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (Tinosorb S) for broad-spectrum coverage. These maintain their efficacy under prolonged sun exposure without degrading, and their fluid-soluble nature contributes to the formula's light, non-chalky finish.

Triple Vitamin C Blend

Three distinct Vitamin C sources work at different levels of the skin. Ascorbyl Glucoside is a stable, slow-release derivative that converts to active ascorbic acid in the skin, providing sustained brightening and collagen stimulation. Kakadu Plum extract (Terminalia Ferdinandiana) is one of the highest natural sources of Vitamin C known, contributing additional antioxidant density. Citrus Sinensis (Blood Orange) extract adds flavonoids that complement the UV defence and support skin radiance. Together they address dullness, uneven tone, and post-sun pigmentation more comprehensively than a single Vitamin C source alone.

Vitamin E — Tocopheryl Acetate

Vitamin E and Vitamin C have a well-documented synergistic relationship in photoprotection. Vitamin E neutralises free radicals that survive UV filtration, and it also helps regenerate oxidised Vitamin C back into its active form — meaning the two actives effectively extend each other's efficacy in the skin.

Niacinamide

Niacinamide (Vitamin B3) is included here at a supporting dose for its melanin-transfer inhibiting effect — gradually fading existing hyperpigmentation and post-acne marks with consistent daily use — and its mild oil-regulating properties.

Additional Actives

Fructooligosaccharides (a prebiotic) support the skin's microbiome and barrier function. Beta Vulgaris (Beet) Root Extract contributes additional antioxidant coverage and a subtle natural pigment that reduces the likelihood of any white cast on deeper skin tones.

How to Use

1. Apply as the final step of your morning skincare routine, after cleanser and moisturiser.
2. Use the two-finger rule — squeeze two lines of sunscreen along your index and middle fingers for a full-face and neck dose.
3. Dot across forehead, cheeks, nose, chin, and neck, then blend in upward strokes until fully absorbed.
4. Apply 15 minutes before sun exposure to allow the UV filters to form a uniform protective layer.
5. Reapply every 2–3 hours when outdoors or after sweating. No sunscreen maintains full efficacy all day without reapplication.

Pro tip: This formula works well as a makeup base. The dewy, non-sticky finish holds foundation without pilling. Allow 2 minutes to fully set before applying makeup on top.

Safety & Suitability

Dermatologist-tested, non-comedogenic, and free from chalky mineral-heavy formulations. Notes by concern:

• Oily skin: The fluid, water-light texture absorbs cleanly without adding grease. It won't eliminate midday shine entirely but sits comfortably without congesting pores.
• Sensitive skin: The advanced chemical filters in this formula are generally better tolerated than older-generation filters, which can cause sensitivity in some people. Patch-test first if you have a history of sunscreen reactions.
• Deeper skin tones: The Beet Root Extract and fluid-soluble filter system mean zero white cast — it absorbs transparently across all skin tones.
• Vitamin C sensitivity: Ascorbyl Glucoside is one of the gentler, more stable Vitamin C derivatives. It is significantly less likely to cause tingling or irritation than pure ascorbic acid formulations.

Frequently Asked Questions

What makes the "new-age" UV filters different from standard sunscreen filters?

Standard filters like Ethylhexyl Methoxycinnamate absorb UV and convert it to heat, but degrade with prolonged sun exposure — meaning SPF protection weakens throughout the day. New-age filters like Uvinul A Plus and Tinosorb S are photostable: they maintain their UV-absorbing structure without breaking down, providing more consistent protection over longer outdoor exposure. They also dissolve in lighter carrier systems, which is why this formula has a fluid finish rather than a thick, cream texture.

Does this replace a Vitamin C serum in my routine?

It reduces the need for one in a morning routine, but doesn't fully replicate a dedicated serum. The Vitamin C concentration in a sunscreen is necessarily lower than in a targeted serum. For mild brightening and maintenance, this alone is sufficient. For active treatment of significant hyperpigmentation, pairing with a dedicated Vitamin C serum at night gives better results.

Can I use this every day, including indoors?

Yes. Blue light from screens contributes to oxidative skin damage with prolonged daily exposure. The broad-spectrum filters and antioxidant actives in this formula are beneficial even on indoor days.

How long before I see brightening results?

UV protection is immediate from the first application. The Vitamin C brightening effect on dullness and uneven tone is typically noticeable within 3–4 weeks of consistent daily use. Fading of deeper pigmentation spots takes longer — 6–8 weeks or more, and is faster when combined with daily SPF reapplication.

Is there a white cast on darker skin tones?

No. This formula uses only chemical filters — no Zinc Oxide or Titanium Dioxide — and the Beet Root Extract adds a very subtle warm pigment. It absorbs completely transparently across all skin tones.

Is this product original?

Yes. usmart.com.bd sources directly from authorised importers of Dot & Key products. Every unit is verified for seal integrity, correct UV filter labelling, and valid expiry before dispatch.
