Frequently asked questions

How does Alpha-Arbutin fade dark spots?

Alpha-Arbutin inhibits the enzyme tyrosinase, which drives melanin production. By blocking this pathway, it reduces the formation of new pigment, visibly lightening existing dark spots over time.

How long before I see results?

Clinical results show significant reduction in dark spots and melanin levels after 4 weeks of consistent use. Layering 2–3 times accelerates visible improvement.

Can I use this on acne scars?

Yes — this serum is specifically formulated to address post-acne discoloration. The multi-ingredient brightening complex targets all stages of hyperpigmentation including acne scarring.

Is it safe for sensitive skin?

Yes. It is hypoallergenic and formulated without common irritants. Patch test recommended for first use, particularly for those with very reactive skin.

Should I use SPF when using this serum?

Absolutely — daily SPF is essential when using brightening actives. UV exposure triggers melanin production which can counteract the effects of the serum.

I give this Company and products five stars

I give this Company and their products five stars because I am 100% happy with them. I have in the past tried everything on the market for the past thirty years and needless to say, wasted so much money but nothing worked. Then I stumbled upon this Company and their products and they worked instantly. Cleared my blemishes, controlling my acne. I use theAnya face wash in the morning and the medicube face cream. At night I cleanse and tone with the medicube cleanse net and toner and finally the medicube serum. I’m also using the Eastern Curlew eye cream am and pm. Amazing products! Hurry go get them!!
