when will i see results?

Retinal works up to 11x faster at the skin level than retinol. Many people notice smoother texture and a brighter tone within 4 weeks of consistent use, with firmer skin and softened lines becoming more visible over 8–12 weeks. Results continue to build with regular nightly use and daily SPF protection.

will this irritate my skin?

Retinal is often better tolerated than retinol because it requires fewer conversion steps to become active in the skin. Our 0.1% retinal is encapsulated for slow release, meaning it penetrates deeper with less surface irritation. Most users experience smoother, firmer skin without peeling or redness — but as with any Vitamin A, it’s best to start 2–3 nights per week and build up as your skin adjusts.

how to use?

1. If you are new to using retinol or retinal, apply it every other night for the first two weeks.

 

2. Apply a small amount to the targeted areas. If irritation occurs, reduce the amount and frequency, and use a moisturizer containing soothing ingredients to alleviate irritation.


 

3. The morning after using retinol, ensure you apply sunscreen as the final step in your skincare routine to protect your skin.


 

4. Once your skin has adjusted to retinol or retinal, you can use it every evening.


 

5. Apply an appropriate amount evenly over your entire face.

what is retnal?
& how it works?

Retinal (Retinaldehyde) is a potent form of Vitamin A that works up to 11 times faster than traditional retinol. It requires only one conversion step in the skin to become retinoic acid—the active form responsible for visible skin renewal. This makes it both highly effective and less irritating.

Frequently asked questions

Can I use this with other products?

Yes. Retinal pairs well with hydrating ingredients like hyaluronic acid, ceramides, and niacinamide. If you use strong acids (AHA/BHA) or exfoliants, alternate nights to avoid over-sensitizing the skin

Can I use this on sensitive skin?

Our 0.1% encapsulated retinal is designed for gradual release, which makes it gentler than traditional retinol. If you have very sensitive skin, start 2 nights per week and build up as your skin adjusts. Always follow with a moisturizer.

Does this help with sunken eyes?

Retinal improves the look of fine lines, wrinkles, and texture around the eyes, but it won’t replace lost volume. It helps refresh and smooth the eye area so crow’s feet and surface lines look softer.

Is this suitable for all skin tones?

Yes. Retinal is effective across all skin tones and does not cause bleaching or uneven lightening. Instead, it helps even out discoloration and promotes clarity.

Is it tested by dermatologists?

Yes. The formula has been dermatologist-tested for safety and tolerability on different skin types.
