Dullness • Uneven Tone • Dryness • Fine Lines • Normal to Dry Skin
HOW TO USE
Apply a few drops to clean skin in the evening. Massage gently over the face and neck. Use alone or as the final step after water-based serums.
If using multiple active products, introduce them gradually and adjust your routine based on your skin's tolerance.
WHY THD ASCORBATE?
Tetrahexyldecyl Ascorbate is a lipid-soluble derivative of vitamin C. Unlike L-ascorbic acid, which is water-soluble and typically formulated at an acidic pH, THD Ascorbate can be incorporated into oil-based formulas and used without the same low-pH formulation requirements.
L-ascorbic acid remains the most extensively studied form of topical vitamin C. THD Ascorbate offers a different formulation approach for people who prefer an oil-based nighttime vitamin C product.
INGREDIENTS
Squalane, Pistacia Lentiscus (Mastic) Gum, Rosa Damascena Flower Extract, Tetrahexyldecyl Ascorbate, Caprylic/Capric Triglyceride, Geraniol.

Reviews
I love this product and have been using it for a couple of years but I have been purchasing from Amazon since it arrives quickly. But, I do not like the new packaging and prefer the amber glass Please keep this option available and I’ll be purchasing from this site in the future. Thank you
Really like this product!
Makes my face feel super soft.
What NOT to dk5- apply & then use red light therapy mask . I got a chemical burn. The lesson in it is, the grade of product is phenomenal. The burn is pretty co trolled but I would compare it to a chemical damage I would pay for . The end result will be fabulous but don’t do that. Just use it in the evening, it’ll transform your skin beautifully.
This is a product that is new to me and I really like it. I feel that it is doing a great job of deeply hydrating my skin as I sleep. It's clearly occlusive, but not heavy or goopy. It feels light and yet rich.
The serum is light and smells nice, but it's oily and doesn't absorb well, so I stopped using it after three tries.
